Be afraid? Is no secret safe today?In WireIN, we often cover electrically related security, such as access control, burglar-alarms, security control panels and CCTV cameras. What we have not done is to look at digital security - fast becoming a big risk for businesses everywhere. Companies today have to adapt to a world where no secret is safe, because almost all data today is digital, and digital information, in whatever form unless highly encrypted, is especially susceptible to unauthorised access and theft.

Consider WikiLeaks, the international non-profit organisation that publishes submissions of private, secret, and classified media from anonymous news sources and leaks. We all know now that WikiLeaks has released thousands of US State department diplomatic cables, but did you know that the organisation is soon to publish files from an unnamed financial institution? Bankers are worried, but are you? You should be, especially if everything is not completely above board and transparent, because in the digital age, commercial secrets are no longer safe. And now, WikiLeaks supporters are cyber attacking those organisations, such as PayPal, that have refused to deal with it.

Businesses large and small are continually storing ever more digital corporate data, but this often just makes them more vulnerable to attack or theft. Moreover, more employees are using social networks at work, which are all about exchanging information – some of it about the employees’ own companies.

This is not the end of the story, for there are viruses too. The Stuxnet worm, discovered last year, is thought to be the first to directly target major industrial plant and utilities facilities. Because of Stuxnet’s extreme sophistication, security professionals have suggested that its creators had state backing (possibly the US and Israel) and was primarily aimed at Iran. True or not, other countries are now indulging in cyber warefare on an increasingly large and frequent scale.

Though most WireIN readers are unlikely to be the subject of such international cyber attacks, they could be seriously damaged by cyber theft or by viruses. Many smaller companies still don’t have proper firewalls (or indeed any), and even large companies still allow employees to use removable media (discs, memory sticks etc), which are highly risky. Who is allowed into which area and why? Ask the questions. Most of all, very few companies have a proper security policy. They should have!

TEST & MEASUREMENT

Andy Baker examines the ways in which infrared thermal

imaging cameras can be used to carry out a wide range of test and monitoring

functions in electrical installations. He finds

that increasingly, added intelligence

and state-of-the-art communication

facilities are making these instruments still

more useful:

paperwork, which means that there is a greater opportunity to be out in the field addressing more tasks and earning extra revenue.

The clamp meter is simply fitted to the first phase and the IR image is frozen complete with the embedded current reading. The camera then prompts the user to add more current readings, one at a time, each being stored in the appropriate image. On this basis three phases require three readings.

Added valueThis is just one way in which the thermal imaging technique is being developed to meet the specific needs of those involved in thermal imaging of electrical systems. IR camera capability continues to be refined and enhanced. The technology is continuing to get smarter. Never before has it been so easy and quick to detect a problem. One of the key drivers is the parallel development of PC-based analysis and reporting software, and application specific software that maximise advances in hardware performance.

In line with the price fall of thermal imaging cameras, so too has that of software. Good reporting and analysis software is now available for less than £1000 and adds considerable value to the overall thermal imaging package. It allows findings to be properly documented so that trends can be plotted and the preventative maintenance programme effectively managed.

Broadening the scopeOn a standard mid-range portable IR camera, the smallest of temperature differences can now be detected, typically 0.03°C or 30mK. Not only does this allow a tiny anomaly to be seen in electrical installations, it also allows the camera to produce sharper images over greater distances. This is of considerable importance in high voltage applications. Another clever new feature is IR window correction that automatically adjusts the camera’s sensitivity to ensure accurate measurement through safety IR windows.

Of benefit to electricians serving a number of sites is the inclusion of built-in GPS. Special software automatically adds the GPS co-ordinates in the thermal imaging report. It also works in tandem with Google Maps so the user can see a satellite image of the inspection site, obtain address information and even travel directions.

Multiple applicationsThe greatest advantage of today’s thermal imaging camera remains its breadth of application. As well being perfectly suited to a broad range of electro-mechanical tasks, it can be used to visualise faults in building structures and for effective energy management. Reporting options are now extensive with packages providing the user with numerous pre-designed report templates. An energy cost

comparison report is one example that allows the easy calculation of achievable cost savings when the identified structural problems are fixed.

The wide-ranging ability of the technology gives it great cost saving potential. It is perfectly possible for the same camera to be used to check a roof for water ingress, examine the integrity of building insulation, monitor the efficiency of underground water pipes, inspect bearings on a motor, as well as look for loose terminal connections in a control cabinet.

Applications for a general-purpose infrared camera can now also include R&D and automation tasks. This is possible as features that were once solely the preserve of the most expensive cameras are starting to be incorporated into less sophisticated series.

Imaging streaming is a typical example. This allows the user to watch a process at start-up and acquire radiometric data at a reasonable speed. Periodic storage is another, enabling snapshots to be taken at pre-determined intervals, allowing the camera to act as a watchman for a variety of applications.

The return on investment is accelerated with every application added to the list. Moreover, what has been achieved to date with thermal imaging is only the tip of the iceberg. It is the subject of continuous development and there is much more to come. Thermal imaging is a dynamic technology and its potential is huge

Andy Baker is UK and Ireland Sales

Manager at FLIR Systems. His

involvement in thermal imaging

technology pre-dates his time

with FLIR, as he was previously

UK Sales and Marketing Manager

for Inframetrics, which developed

the first portable un-cooled

thermal imaging camera and was

subsequently bought by FLIR.

Andy Baker initially had a regional

sales role with the newly expanded

FLIR, but has more recently been

Distribution Manager.

Thermal imaging it’s getting smarter

The correlation between temperature and electrical load is well established, so for

many years it has been standard practice for thermographers to take separate load ratings during an infrared (IR) electrical survey. Typically, the camera user would note down readings from a clamp meter, adding them to the survey report some time later. Over the course of the survey, this created a lot of data and it was all too easy for readings from different instruments to be lost or mixed up.

Now the two processes have been combined and it is possible to buy a thermal imaging camera and clamp meter that talk to one another because of Bluetooth technology. This development allows measurement data from the clamp meter to be automatically embedded in the IR image, so bringing brings greater accuracy and intelligence to thermal imaging inspection.

This also means the electrician needs to spend less time compiling data to generate a report. Importantly, it also means less time spent on

Main Image: In recent years the price of thermal imaging cameras has decreased continuously enabling many more people to discover the advantages of the technology. Some models can cost as little as £895.

COMPANY PROFILE

In November 2010 Metartec signed a two-year distribution agreement with Circutor S.A. of Barcelona, Spain, to become the UK distributor of Circutor’s electrical energy efficiency products:

Circutor S.A. of Barcelona, Spain is one of the leading European companies focused

on the design, manufacture and marketing of electrical energy efficiency equipment. The company offers products and solutions ranging from measuring and electrical control, protection and control, power quality and metering to PF correction and harmonic filtering.

Metartec was keen to team up with Circutor because both companies have a very similar ethos, encouraging the development of innovation and technology in order to offer integral solutions for the electrical market. Another fundamental reason for this partnership was because of Circutor’s commitment to developing complete solutions for electrical energy efficiency matters. This can be further supported by Metartec’s strong position in the critical power supply market.

This strategic partnership has paved the way for the creation of a new line of business within Metartec, extending the company’s field of operation to offer a full range of high quality equipment specially designed and developed

for the electrical energy efficiency sector.

The importance of electrical energy efficiencyElectrical energy efficiency is the reduction of contracted power and electrical energy required from the system, without affecting normal activities being carried out. It is important for the following reasons:

It helps to keep the system and environment sustainable by reducing CO2 emissions through minimising energy generation requirements.

It improves the technical management of installations by increasing their performance (increased available capacity) and avoiding process downtime and breakdowns (controlling leakage and eliminating disturbances).

As a result, electrical energy efficiency reduces the financial costs of the operation for installations and processes. With this in mind, Metartec felt it was essential to offer its customers complete solutions that focus on improving their electrical energy efficiency. To embrace this new line of business, the company has launched a new sub-brand called Metartec e3 by Circutor. Metartec remains the leading brand name with e3 depicting the electrical energy efficiency market by the equipment manufacturer, Circutor.

As Circutor S.A has chosen Metartec e3 to be the UK distributor of its electrical energy efficiency products, it is the ‘one stop shop’ supplier for all UK businesses to satisfy their needs in the sector. This subdivision will be fully supported by Metartec’s team of experts and technicians, who will dedicate a large amount of time and resources to assist with its development. The company will be able to supply the UK market with Circutor’s electrical energy efficiency products though its substantial network of critical power supply customers.

Metartec e3 offers bespoke solutions to suit any application at very competitive prices. Every product in the range has its quality proven by Circutor’s rigorous quality testing, providing customers’ with very high reliability. The brand also provides a wealth of experience within the sector, with a support team of experts being available to provide 24/7 assistance. There is also rapid delivery of products and solutions.

Metartec’s e3 equipment and systems provide an overall integrated solution, supplying an analysis of the results by user-friendly SCADA software called Power Studio. The extensive product portfolio includes power factor correction and harmonic filtering equipment, as well as high speed statically switched capacitor banks.

Circutor’s research and development team continually presents new opportunities to the electrical energy efficiency market, with around 30 innovative products being developed each year. Metartec e3 is pleased to be associated with Circutor and looks forward to bringing innovations to the UK market.

Self-testing alarms save moneyIt is often more cost-effective and reliable to install an emergency lighting system with automatic self-testing than to fit a system that must be tested manually, according to ICEL, the emergency lighting arm of the Lighting Industry Federation.

BS5266: Part 10 – the emergency lighting code of practice – and Fire Safety legislation under Section 7 (testing, maintenance and record keeping) mean that a ‘responsible person’ must test emergency lighting systems regularly. Monthly and annual testing of every luminaire is necessary, with central battery system indicators being visually inspected daily.

Accurate records must be kept. In large buildings, this can be a lengthy job that may be difficult to achieve while keeping the building in a legal, fully working state. Such testing, therefore, can be expensive and disruptive.

Automatic testing can solve these problems by regularly checking, without human intervention, that emergency lighting batteries and luminaires are

Said McGaw Electrical MD, John McGaw: “Not only are we bringing the homes up to current standards, but Hager’s products have minimised disruption for tenants during installation and provide a safer, lower maintenance solution in the future.

“We have found the new Sollysta range of wiring accessories easier and faster to fit than alternatives. In particular, the loop in neutral connection in the wall switch means that we don’t need to fit a separate connector block in the back box

as we do with all other ranges. Pushing a connector block into the back box behind the switch compresses the cables putting extra strain on the terminations, so having a loop in neutral terminal in the accessory is far preferable. It also means that we don’t need to retrofit deeper back boxes”, concluded John.

Hager consumer units are also being used. Each circuit is protected by individual RCBOs, preferred because if a circuit trips as a result of earth leakage, only one circuit is affected. This means that it is more likely that the council can plan a maintenance visit rather than respond to the call as an emergency, saving both time and future maintenance costs.

McGaw Electrical has also fitted a DIN rail mounted emergency lighting module in each consumer unit. This lamp lights automatically if mains failure occurs, which makes things easier for visiting electricians and tenants alike.

Hospital gets Marshall-Tufflex germ-busting treatmentMarshall-Tufflex’s Odyssey Bio cable management system, with built-in antimicrobial properties, is helping prevent infection within the refurbished neonatal unit at a major Women’s Hospital. This £7m combined refurbishment and new-build project uses the Odyssey Bio fully curved profile CAT 6 compliant trunking system.

Silver-ion protection is added to Bio’s PVC-U formulation during manufacture,

ensuring that Odyssey Bio continues to neutralise and kill dangerous bacteria such as MRSA, E-Coli and Salmonella even if the trunking is scratched or knocked. Such antimicrobial properties are perceived as being a huge benefit to the hospital, which is committed to ensuring that its staff, patients and visitors are protected from healthcare associated infection.

Odyssey Bio has also allowed future proofing sections of trunking in readiness for any later re-configuration that might be necessary.

Monitoring energy use ‘is essential to avoid tax’Changes to the CRC Energy Efficiency Scheme announced in last year’s Comprehensive Spending Review mean the scheme is effectively a carbon tax on larger companies and public sector bodies, so these organisations must accurately monitor and manage their energy use, according to Schneider Electric.

Rachel Cooper, energy consultant for Schneider Electric, said the revenue raised by selling carbon allowances to companies will no longer be recycled back to organisations that perform well in the scheme, but used instead to support public finances, including environmental schemes.

“The bad news,” she said, “is that they will be paying significantly more than anticipated for the energy that

they produce through this tax.”However, under the revised

scheme organisations will not need to purchase allowances for 2011/12 until 2012. This, said Cooper, “allows organisations to prepare for the start of the scheme by ensuring that they understand their energy usage and are taking action to monitor and reduce”.

A consultation is being launched next month on how the CRC could be simplified and clarified.

Although the details of the scheme are unknown at present, organisations will need to report on and pay for their energy use. Cooper believes organisations should act now to ensure that their data management is efficient and effective. They should also review energy saving projects in the light of the changes, because they may make projects more attractive to the organisation with improved return on investment.

Box cuts energy use for lightingThe E-Box is a power optimisation unit that can cut energy consumption for lighting installations by as much as 45%. The device, available from the specialist products division of Newey & Eyre, fits between the electricity supply and the lighting load and uses voltage optimisation, power factor correction and harmonic filtration to cut energy use.

E-Box is single phase and sits in-line at the distribution board or can be fitted to individual circuits. It constantly monitors load and regulates the supply voltage, and uses digital capacitance to solve the poor power factor problem often found in lighting circuits. Filtering out bad harmonics and removal of harmful spikes also yield substantial savings.

Using the E-Box, sodium vapour and mercury vapour lamps will use 30-45% less energy, fluorescent lamps with standard ballasts will use 30-40% less, and metal halide lamps will use 30% less. Savings with halogen lamps are about 25%. More modest savings can be made with compact fluorescent, LED replacements and T5 adapters.

Industry ‘wastes millions’ on motorsUnnecessary motor downtime, repairs and inefficient running are costing UK industry millions of pounds because companies are not managing their motor inventories properly, according to motor maker ABB.

The company is launching MotorAdvantage, a scheme to encourage the process industry to uncover the true cost of running its electric motors. There are three stages. In the consultation stage, ABB examines the installed motor asset register for the plant and, working with local engineers, identifies up to five critical applications that are running either continuously or for more than 4,000 hours a year.

In the appraisal stage, a motor engineer visits the plant and inspects the chosen motors, the inventory of spare motors, and the energy and maintenance plans.

Finally, the findings are analysed and potential savings identified using specialised software. An action plan is prepared with a detailed engineer’s

report that highlights applications with the greatest potential to save money.

ABB first became concerned about the state of the UK electric motor installed base when it noticed the widening gap between the value of new industrial low voltage motor sales – about £70m – and the size of the motor repair market, which is conservatively valued at twice that amount.

Smart lighting ushers cinema-goers to safetyIntelligent lighting is an essential part of the fire evacuation strategy at a new cinema complex on the second floor of Belfast’s Victoria Square shopping centre. The Odeon cinema has eight screens and a capacity of nearly 2,000 people, and it was essential to direct the public out of the building in the absence of staff and to motivate cinemagoers to use fire exits rather than simply evacuating through the cinema entrance.

Independent consultant CS Todd & Associates (CSTA) identified a proprietary system, the Modular Intelligent Lighting System (MILS) that it thought would be suitable for the application. The system was developed for the marine industry to direct passengers on ships to life stations.

The system comprises low-level moving green LED strips, in combination with flashing directional arrows, which can be built into fire exit signs. The way guidance can change for different phases of the evacuation.

MILS was further developed to switch off exit signs that are not to be used because they would lead evacuees towards the fire. The green exit sign is replaced with a red cross similar to the type used on motorways to indicate a closed lane.

Combined with voice alarm warnings to follow the green flashing lights, the system ensures that all available exits from each screen are used, even in the complete absence of staff.

A team of four from CSTA worked with fire alarm installer ADT and tested the software for the fire protection system for each of 60 possible fire scenarios. For each scenario, the correct programming had to be confirmed for all three phases of an evacuation.

The public areas of the cinema were divided into 19 fire detection zones. A Category L1 addressable fire detection and fire alarm system was installed along with a public address/voice alarm system. The sequence of phases of evacuation is determined by the location of the fire, as indicated by the address of the originating detector or the location of the call point operated.

CCTV cameras monitor all the screens and critical points in the escape routes, including the exits to fire escape staircases. The CCTV monitors can be viewed at the normal fire control point in the foyer.

ADT won the Fire Safety Engineering Project Design Award at the Fire Excellence Awards for the Belfast Odeon project.

BEAMA welcomes continued support for renewable heat Electrotechnical trade association BEAMA has welcomed the Government’s continued support for a Renewable Heat Incentive (RHI), which was announced in the Comprehensive Spending Review. The incentive will be launched in June 2011. BEAMA marketing director Kelly Butler said the UK’s legally binding renewable energy target always meant that a Renewable Heat Incentive would have to be launched, despite the economic challenges facing the country.

Butler said: “The Government’s 2050 Pathways Scenarios largely point us towards a future dominated by the electrification of heat and transport. The Government’s announcement will set us on the right path to meet renewable targets, and build a confident heat pump market to meet the longer-term 2050 aspiration.”

He added: “The challenge now is to ensure the scheme is designed to be attractive to the customer – and help grow the market for important technologies such as heat pumps.”

BEAMA said the heat pump industry must now gear up to deliver 1.4 million heat pumps to be installed by 2020, as the association predicted.

Avoid the cost of accidentsIOSH Managing Safely is the flagship occupational safety training course from the Institution of Occupational Safety and Health, and is designed for managers and supervisors in all industry sectors.

Accidents and ill health are costly to workers and their families, but also hurt companies because, as well as the costs of personal injuries, they may incur far greater costs from damage to property or equipment, and lost production.

Every working day in Great Britain at least one person is killed and more than 6,000 are injured at work. Every year three quarters of a million people take time off work because of what they regard as a work-related illness.

The course gives managers and supervisors an understanding of safety management systems, hazard identification and control.

Supervising electricians will need Level 3 qualificationsAll new applicants for the position of qualified supervisor will have to hold a Level 3 qualification, or equivalent, from July. The Institution of Engineering and Technology (IET) said the change would help set the benchmark for safety in the electrical contracting sector.

Anyone who applies to become a qualifying supervisor who is legally responsible for the day-to-day technical activities of electrical companies to Part P of the Building Regulations – which applies only to England and Wales - will need the new QCF Level 3 NVQ Certificate in Installing, Testing and Ensuring Compliance of Electrical Installation Work in Dwellings. The qualification will include an occupational competence assessment.

Qualified supervisors responsible for all types of electrical installation will require the new QCF Level 3 NVQ Diploma in Installing Electrotechnical Systems and Equipment (Building and Structures). Candidates will have to pass an assessment of occupational competence.

The requirements will be imposed on those applying for the post of qualified supervisor, but will not be applied retrospectively to qualified supervisors already in post.

IET chief engineer Geoff Cronshaw said: “It is absolutely right that industry continues to make its mark on regulation. This is a positive move for the industry.”

The eight-month project includes a full internal refurbishment and fit-out of the 5,865 sq m building in Cadogan Street, which will accommodate about 500 staff from five other sites.

BBES will carry out a full mechanical and electrical fit-out, including daylight linking lighting controls, seasonal commissioning and inverter-driven motors. Many of the installations will be prefabricated modules.

For increased efficiency, existing switchgear and boiler house plant will be reused, as will sub-mains cabling and pipework in the main risers.

When complete, NHS National Service Scotland will use most of the building. Levels five and six will be sub-let.

Novel driver dims LEDs to 0.3%Electronics specialist Controlled Speed has launched a driver for lighting that dims LEDs to 0.3% of full output without flickering. Previously, the technology behind LED lighting only allowed flicker-free dimming to 10%, which excluded the light source from many applications.

As LEDs have become more popular for general lighting applications, there has been a growing need for them to perform in the same way as traditional lighting. The Innovation Lighting Technology division of Controlled Speeds develops custom power supply LED drivers that deliver optimum current and voltage to the light source.

Controlled Speeds believes the driver will open up new markets for LEDs.

Philip Astley, business development director at Controlled Speed, said: “Our research and development team managed to produce

a fully dimmable finished product range in just three months. Lighting designers and manufacturers will no longer have to compromise on dimming requirements and this range now helps to meet the gap between traditional and LED lighting.”

The first order of 4,000 drivers has been delivered to a major leisure operator and a family of housed and un-housed dimmable lighting drivers for flicker-free dimming from 100% to 0.3% or 0.5% (dependent on model) for 20W output is available. Models with outputs of 50W and 100W will be available early this year.

The NICEIC will continue to report offending companies to Trading Standards and they face a heavy fine or sentencing. For example, Shaun McKever, trading as S&M Electrical Contractors in Milton Keynes, was recently handed a 12-month Community Order with 150 hours of unpaid work after he was caught using the NICEIC logo on business cards and a website listing.

The current economic climate means more and more untrustworthy traders misuse the logo as a way to win work. NICEIC has received 185 reports in 2010. In 2008 and 2009 the figures were 156 and 154 respectively.

Faulty alarms ‘responsible for most prison call-outs’Faulty fire alarms may be responsible

for as many as 1,000 of the 1,141 false alarms in Scottish prisons over three years. Only 141 of the false alarm calls were malicious, according to figures published in The Scottish Sun. The paper also revealed that false fire alerts

in Scottish prisons have cost £1.2m in three years.

Fire and rescue services were called to jails for false emergencies a total of 1,141 times in this period. There were 240 genuine call-outs.

Osram lighting designer Dr Martin Möck designed and engineered PirOLED. The 80 centimetre-high aluminium double helix is inspired by two ideas – the organic structure matches the DNA helix and the shape

it forms is derived from the pirouette, a turning movement in ballet.

The five Orbeos panels have a light density of 1,000cd/sq m and should have an operating life of 5,000 hours. The glare-free light density of the OLED panels has a soothing effect, similar to that of candlelight.

The colour temperature of the OLED panels is warm white (2800K) so PirOLED is suitable for lighting that is atmospheric and functional at the same time.

Park will showcase Scottish building innovationBuilding work has started on BRE Scotland’s Innovation Park on the site of a former steelworks at Ravenscraig in Lanarkshire. Alex Neil MSP, minister for housing and communities, was joined by representatives from BRE Scotland, North Lanarkshire Council and Ravenscraig Ltd to mark the start of the project, which is designed to influence the future of housebuilding in Scotland.

North Lanarkshire Council recently awarded BRE Scotland £500,000 for the first stage of the development. A new car park will be included and street lighting will be installed.

The two-acre park will incorporate four demonstrator houses and a visitor centre, and will channel over £2m of new technology investment. The houses will showcase how homes of the future will tackle affordability, energy efficiency, the use of recycled materials, carbon emissions and sustainable construction methods.

BRE Scotland is now inviting companies from across Scotland to submit proposals for demonstrator homes.Cooper makes two

UK acquisitionsCooper Industries has acquired Mount Engineering and Apex Lighting Controls. The two UK companies will expand the manufacturer’s hazardous area products and energy-efficient lighting portfolios.

Mount Engineering makes threaded adaptors and reducers that are Ex certified for use in potentially explosive or hazardous areas. It sells and distributes industrial valves and actuators to the oil, gas, petrochemical and process industries worldwide. It will become part of the Cooper Safety division of Cooper Industries.

Apex Lighting Controls is a private manufacturer of lighting controls. Its products and services manage lighting and energy usage for commercial, government, and healthcare markets in Europe, the Middle East and Asia. Apex will become part of the Cooper Lighting division of Cooper Industries.

Cooper Industries’ chairman and chief executive officer Kirk Hachigian said: “The acquisition of Mount Engineering represents a strategic fit with Cooper Safety’s existing offering of cable glands and Cooper Crouse-Hinds’ portfolio of harsh and hazardous solutions.”

Cuthbertson Laird Group is one of the foremost electrical test instrument distributors in the UK, with offices in Scotland, Northern Ireland and England. Today, the company is headed by MD Peter Greenshields, and is a specialist distributor, exporting instruments and test equipment worldwide:

A brief historyCuthbertson Laird Group, which is based in Hamilton, Scotland, but which also has regional offices in Newtownabbey, Northern Ireland and Leeds in England, was originally established in February 1980 by Alan Cuthbertson and Jimmy Laird. Both men had extensive previous experience with Edgcumbe Instruments, but for the first few years, the initial business sector addressed was power tools and they were the sole employees.

In the early 1980s, however, it was decided to put their previous experience to good use with the company graduating to electrical test instruments,

on which it is now focused - a natural progression that has made the company very successful. At this time, Cuthbertson Laird was doing good business supplying multimeters, oscilloscopes and other portable electrical test equipment sold into the then burgeoning offshore oil sector, particularly through Aberdeen. Rather more specialist test equipment was also supplied, such as large 5kV AC and DC pressure sets.

Within a few years, the company had grown sufficiently that it needed to move from its Hamilton tenement building to much larger premises, which it had built from scratch in Hamilton – today the HQ still. Peter Greenshields joined as a director in 1985. Later becoming MD, he has grown the company ever since, opening the Newtownabbey, Northern Ireland and Leeds offices in the process.

Cuthbertson Laird todayCurrently, Cuthbertson Laird Group has 27 full-time employees, some of whom work at the Newtownabbey and Leeds

Accreditations and servicesAs a supplier of goods and/or services to the oil & gas sector, Cuthbertson Laird Group, which is accredited to ISO 9001, is a Registered Supplier with First Point Assessment Ltd. (No 40804), and its calibration laboratory in Scotland is UKAS registered. The company is also a registered supplier on the Achilles UK Utilities Vendor Database (UVDB No 75084), and Public Contracts Scotland.

As a member of Fluke’s Industrial Maintenance Partnership (IMP), Cuthbertson Laird is a specialised distribution partner that can demonstrate, supply and support Fluke’s broad range of test instruments and other industrial test tools.

The company is an authorised repair centre for most of the major instrument manufacturers. Its field sales personnel and calibration technicians all receive regular training from manufacturers and can advise on technical and commercial problems. Approved Repair Centre status is held from leading manufacturers, HVI, Megger, Seaward & Testo.

Cuthbertson Laird’s years of experience in the sale and service of precision, high-quality equipment for the testing and maintenance of electrical, industrial and process plant brings its own advantages to existing and potential customers, who can call upon the complete advisory service offered. This includes servicing facilities for an ever-widening range of measuring devices.

Instrument calibrationHaving accredited UKAS Calibration Laboratory status, the company also has the facilities for the calibration of electrical, temperature, pressure, HVAC, safety, airflow, torque and dimensional metrology test & measurement equipment at its offices. Customers’ test instruments, meters and test sets can be collected for calibration or repair throughout the UK. In-house calibration certification is to BS EN ISO/IEC 17025:2005, while calibration certificates

are traceable to National Standards, including UKAS (Lab No 0316) for compliance with customers’ own Quality Assurance systems.

Calibration Service Contracts can be arranged. These can be very cost effective for companies requiring annual or three-year contracts at fixed calibration prices. On-site calibration by arrangement can be provided for companies having larger test equipment inventories or where instruments are fixed. This prevents unnecessary downtime and the complications and risks of shipping instrumentation off-site. Moreover, the on-site calibration program provides customers with the flexibility to schedule the work at their convenience with minimal interruptions to manufacturing processes.

The futureA significant and increasing proportion of Cuthbertson Laird Group’s sales now go to export, and the recent expansion of the company’s Export Department has opened up many new opportunities for selling to countries across the world, including the Middle East. This drive will continue, said Peter Greenshields, who also noted that new instrument products and sectors are increasing business opportunities.

He cited test instruments for thermal imaging in particular (represented by FLIR, FLUKE & TESTO). The cost of infrared (IR) thermal imaging cameras has come down to such an extent that these are becoming almost consumable items for electricians and electrical contractors. Other sectors that are growing fast include power monitoring, renewable energy (especially wind turbines) and HV equipment, with 17th Edition test equipment always in demand.

“Overall”, commented Peter Greenshields, “we at Cuthbertson Laird Group are optimistic about future business, and we will be expanding our calibration facilities and optimising on our present range of new test equipment

CABLE MANAGEMENT

Modern cable handling equipment can provide very significant safety, convenience and cost-saving benefits to electrical wholesalers. There are advantages for electrical contracting customers too, as Pat Delaney reports:

Over the past few years, the Health and Safety

Executive (HSE) and electrical wholesalers have strived to

improve the safety aspect of pulling and cutting lengths of

cable from rack mounted cable drums. This follows a

fatal accident concerning an individual using an electrically operated cable-winding machine having his back to the rack whilst operating the machine. The cable snagged the drum,

which then stopped rotating and the whole

racking system toppled over.Any improvement is to

be welcomed, but even so we cannot

be complacent. Whether electrical wholesaling branches are large or small, if they are dispensing cable from racking systems, they

are only required to show that they

are meeting the very basic requirements.

These are spelt out in

loading the cable onto the racks. In most cases this is done using a forklift, where - sadly - crude wedges of wood are often used to stop the shaft moving whilst on the forks. So why take this risk, when simple and inexpensive custom designed products are readily available in the market?

Using one of these alternatives not only avoids any slippage of the drums, but also more importantly, guarantees the safety of the operator(s). The simplest product consists of a steel adaptor that fits over the forks and is secured by wing nuts. The end of the adaptor is designed to fit snugly onto the cable drum spindle and allows the safe lifting of the drum onto the rack with no chance of accidents. Another benefit of this adaptor is that only a few millimetres on either side of the forks are required to insert the drum safely into its bracket, allowing the racking to be designed with minimum space either side of the drum. This reduces the overall footprint of the racking system.

Safety first with rackingManufacturers of racking continuously develop and improve the design, and hence safety, of their equipment, but this in itself may not be enough unless it is installed correctly in the first place.

Once in situ, it is still important to perform maintenance checks on the system at least on an annual basis to ensure continued safety. To maintain machinery is almost a given, but how many wholesalers can put their hands up and confirm that they carry out annual safety checks to their cable storage facility. We all know that it is a requirement of PAT testing to ensure the electrical safety of equipment used, but here we are talking about mechanical safety, so do we have a different set of rules for this?

Remember that the whole structure is under

constant stress in all directions and there is a drum turning on its spindle, so a simple safety check each year will highlight any structural defects and identify any part that needs replacing - such as a cable drum shaft or spindle. Such checks will also ensure that the brackets are functioning correctly. With constant drum rolling, wear will take place, hence any static spindle brackets can become dangerous over time with wear and tear from the spindle, that is why spring loaded safety brackets are the preferred option for safety conscious operators. These not only provide greater safety over time, but also make life easier when loading and unloading drums onto the racking.

Good cable racking systems have other advantages. It is not uncommon to see large numbers of cable drums strewn across the floor of a warehouse, so in many ways the installation of racking can in itself help to improve safety at electrical wholesalers - the racking itself can provide a tidy and organised storage facility.

Removing this obvious hazard of clutter is a clear way to reduce the potential for injuries, but what about the lifting and supporting of individual cable drums (which can weigh anything up to 1 tonne). Often this is done manually when no forklift is available, hence increasing the likelihood of back injuries. Then there are the supports, many of which are antiquated and should quite frankly be condemned. Modern lifting jacks - either manual worm screw or hand pumped hydraulic - can remove the risk of many injuries that occur daily.

In any case, investing in a racking system, whether for large of small cable drums, not only improves the procedure of providing cut length cable to your customers, but also frees up valuable floor space that could be used far more efficiently.

Below: Showing properly designed racking by CEF. This provides greater safety and makes life easier when loading and unloading drums.

an HSE document, but in summary, these requirements are:

• The racking system should be purpose made for the job intended, and tests should be carried out to ensure the weight carried is within the framework’s design tolerance.

• Safety hooks should be used to ensure that the cable drum shafts are secured and will not spring out when tensioned.

• The racking system should be installed correctly and bolted to the floor and, where necessary, to the walls.

• That adequate facilities must be employed if using a forklift to ensure that drums supported on shafts will not roll off the forks.

• The operator must use a foot-controlled actuator that stops any electrically operated cable-winding machine if the weight of the foot is removed.

• The operator should stand facing the racking system and must be aware at all times of any snagging of cable, or any other potentially dangerous occurrence.

• Electrically operated cable machines must have facilities to stop if the cable tension becomes too great.

Loading of the drumsCable racking is not like conventional racking; it is under constant tension from the pulling of cable (at varying angles), the weight of the cable (vertically downwards) and the positioning of the cable by a forklift (horizontally from the front). Usually racking only has to deal with tension in one (vertical) direction, supporting the material loaded onto it. Not only that, with cable racking, the higher the structure, the more prone the rack also becomes to all these forces.

There is clearly much emphasis on the pulling of the cable itself, but damage and potentially dangerous situations can also arise when

Why a forklift?A forklift is probably the most versatile machine any wholesaler can have. But, there are obvious drawbacks:

• They are expensive to purchase.• They require a large space to work in.• They require additional area and space for

charging or require a gas storage facility.• They require trained personnel to

operate them.• They need a lot of maintenance.• They can cause accidents to other

personnel and equipment.

So for cable storage and dispensing, get rid of them! Purpose made hydraulic drum lifters are readily available. To operate them requires only simple training from the manufacturer, they use very little space, and they are much safer than forklifts.

Small is beautifulFinally, at the other end of the scale, there are small cable drums to consider such as those for flexible cables and twin and earth. These are not so much of a safety hazard as their larger counterparts, perhaps, but remember, you do not need the same large section standard racking to cater for them. They are, however, probably more of nuisance than say the larger wooden drums. They can be scattered here, there and everywhere, so not only can they cause a problem with untidiness and take up an inordinate amount of space, but they can also make it difficult to locate the correct drum and thus ensure good stock rotation. Moreover, it is not uncommon the see many partly used drums of identical cable size in use at the same time.

Small racks are readily available at low prices

and can be tailor made to squeeze into the smallest of spaces available. There is even ‘cassette-type’ racking that is semi-portable and allows you to expand as the business grows. With this type of racking, the drums are safely stored, are easier to use and they are clearly identified for ultimate efficiency.

Ensuring good standards of health and safety at work for cable handling is not rocket science. Just take care to use proper cable racking systems and procedures. They are vitally important in helping to avoid serious and even fatal accidents in the warehouse, so don’t make do with Heath Robinson contraptions when economical solutions are readily available

Des Byrne, branch manager of electrical wholesaler Eurosales which has three branches in Dublin, believes that the interactive facility can really help educate the market on how to distinguish between good, bad and indifferent lighting products. He plans to bring groups of customers and staff to the centre on a regular basis.

Mr Byrne says:”Buyers and staff need more opportunities to learn how a variety of light sources, colour temperatures and optics enables a variety of lighting effects to be achieved.”

Aurora manufactures all four elements of lighting and so the facility features two showrooms. The first showcases the company’s low-energy lighting ranges Luna and Specification LED, so that customers can examine the colour temperature and light output of low-energy replacements for halogen and incandescent lamps. The second is dedicated to lighting fittings, power supplies and controls.

Case study images provide inspiration on completed retail, residential and commercial applications that deliver different lighting effects using modern light sources.

Aurora Dublin’s Des Duignan says: “Our aim is to demystify the complex subject of low-energy lighting and to make accurate comparisons between products. The Northern Ireland facility has closed but business in the north remains exceptionally brisk. We will be actively encouraging our customers from all of Ireland to take advantage of Aurora’s new facilities.”

Visit Aurora, by appointment only, in North Business Park, Finglas, Dublin, junction 5 of the M50. The showroom is less one minute from the M50 or less than 10 minutes from the M1. Visit www.aurora.eu.com, contact Des Duignan on +353(0)1 891 4022 or +353 (0)87 694 1964, or email des.duignan@aurora.eu.com or andrea.duignan@aurora.eu.com

Despite stagnation in the Irish new build market, LED is showing significant growth in supporting refurbishment where contractors are expected to deliver measurable savings in Total Cost of Ownership (TCO). In terms of return on investment, the facts speak for themselves as an LED product delivers a 40,000 hour lamp life or more.

The opening of the low energy specialist’ new state-of-the-art showroom in north

Dublin will provide both an educational resource to wholesalers, contractors and specifiers across all of Ireland.

Orders placed before three pm will be delivered next day throughout Ireland. Customers can just place their orders by phone fax or email in the usual way and their products will be dispatched same day using a fully trackable service. All current catalogues can be viewed on line at www.issuu.com/auroralighting.

Aurora has chosen to make this significant investment to service a major gap in the market for a state of the art lighting showroom and training facility. Aurora’s new services include lighting design, energy audits and site surveys.

The centre, which opened officially on 14th January 2011, is expected to become a key resource to the lighting industry. It features an interactive facility giving wholesalers, lighting designers, electrical contractors and product specifiers the chance to trial lighting effects in-situ and to understand the very latest technology.

Practising energy savingAurora practises what it preaches on energy efficiency. Even with every light switched on, the Dublin showroom displays run on 400W and the rest of the 6,500ft2 facility runs off just 1.5kW - less than a domestic refrigerator.

Des Duignan of Aurora Dublin has described the Irish market as leading the way for the British Isles in adopting energy efficient lighting. He says that LED products have been developed to the point that their performance makes them a perfect substitute for halogen:

Ireland becomes leading light on energy efficiency

Wireless fire detection systems are fast becoming the ‘must have’ for many installers and end users. Now, the heat is being turned upon the latest fire industry technology, as Eurotech Fire Systems’ Vincent Agius reports:

Although wireless fire detection is not new, the technology is evolving rapidly. However,

to ensure that novelty does not compromise safety, as of March 2011 all wireless fire detection systems have to be approved to the new European EN54-25 Standard.

Eurotech Fire Systems (www.eurotechfire.com) supplies the leading EN54-25 approved systems and is believed to be the first to gain full Loss Prevention Certification Board (LPCB) approval

to the new standard. These systems offer a complete approved range, using ‘intelligent’ optical, heat or multi-sensor detectors, as well as AV devices and modules.

The wireless option is fast heading to the top of customer charts. There are a number of very good reasons for choosing wireless detection systems - not all of them financial.Speed of installation, flexibility and architectural compliance are also big plusses for wireless.

The practicalitiesAt the risk of stating the obvious, the most important benefit of wireless fire detection systems is that they are wireless. In practical terms this means they are totally flexible.

They can be fitted from scratch using only

wireless detectors, sounders, beacons, call points and even voice sounders. However, they can also provide a ‘hybrid’ solution, integrating wireless with hard-wired systems. These are ideal, for example, for property extensions or where a whole new building is added to an existing site. Avoiding additional cabling, wireless units can be installed and the devices added to an existing system simply by including the appropriate module.

Wireless systems are also proving popular for the ‘temporary’ market, providing the ideal solution for event and exhibition organisers who frequently require robust, compliant fire detection in structures such as marquees and temporary show halls.

For architects, particularly those specialising in renovation, the wireless solution is becoming a metaphorical lifesaver as well as a literal one. The challenge of fire detection in listed buildings is difficult enough because of the age and materials used in such properties. Add to that the regulations concerning structural change, including re-wiring, and wireless fire detection becomes the only realistic option for

this type of renovation. Speed of installation is also a big plus for

wireless systems. Because the whole system can be set-up and programmed off-site, it is possible to reduce installation times from days to hours. This also means that disruption to the customer, and other trades, is minimal. In public buildings, and particularly in hotels, this is essential and – amazingly - a wireless fire detector and sounder can be installed in an hotel bedroom faster than the room itself can be cleaned.

Overcoming wireless worriesFor most customers considering wireless fire detection solutions, there are two main concerns: reliability and cost.

For any fire system, reliable and robust interaction between fire detectors and control panels is critical; even more so where a wireless interface is involved. With the latest technology, bi-directional communication solves this problem. Every few seconds, the panel ‘talks’ to each address and every device ‘checks-in’ with the control panel. This constant bi-directional

WIRING ACCESSORIES

Over the decades, the installation of wiring accessories has been made ever simpler through product development, careful design and technological improvements. So, how is it possible to make it easier still? In fact, there is much room for improvement, as Jane Yorke argues:

While good aesthetics and smart technology have driven much of

recent wiring accessory development, have manufacturers forgotten about the installer? Perhaps not, but the evidence would suggest that we could do better.

Many improvements, existing or potential, are just the application of common sense.

Take the humble wall switch (Fig 1). There is an ongoing debate about where exactly you should make the loop connection for the neutral conductor of a lighting circuit. Should it be in the ceiling rose or behind the wall switch using a connector block? There are potential problems with both solutions.

If you make the connection behind the ceiling

rose, you will be working above head height. This makes the job both time consuming and awkward and you need to take care to ensure that all of the terminations are secure. Even if they are secure, many would argue that they are not readily accessible for inspection and testing to meet the requirements of BS7671:2008.

The alternative is to complete the neutral loop connection at the switch and to house a joint in that conductor within the enclosure (Fig 2). Both the NICEIC and the Electrical Safety Council state that this is acceptable practice. The switch is at a more convenient height, so it is easier to make the connections and it is readily accessible for future inspection.

Until now, however, the only way to complete this connection is to use a connector block for the incoming and outgoing neutral conductors. Many electricians consider that this is bad practice because the free terminals can move and place strain on the connections. The connector block is pushed into the metal back box, so if a cable becomes detached, this could make the installation live and it also leaves

Further improvements through simple accessorising

chatter ensures that any signal or unit failures are almost instantly picked up.

Where weak signals are encountered, boosters can be installed to overcome the problem. Eurotech Fire Systems has recently installed a wireless detection system in a property where the walls were more than three feet thick and it worked faultlessly. Even if two systems are installed adjacent to each other, there is no danger of signal ‘bleed’ or crossover, thanks to site-specific coding.

When it comes to cost, all of the above leads to a solution which can offer a better value overall package than a hard-wired system. In many cases, the combination of time savings, lack of wiring, ease of installation and use of detection hardware with a standard appearance, can mean significant cost reduction.

Perfect for most, but not for allIt is clear that wireless fire detection is the latest in a history of developments that has harnessed technology with life and property-saving fire industry know-how. In many cases it offers significant benefits over traditional fire detection applications.

However, there are some specialist environments – such as the need for smoke and steam differentiation requiring dual-wave optical technology, or premises that need air sampling detection – where Eurotech’s other range of detection is better suited, either as hard-wired or hybrid wireless systems. But it’s only a matter of time before even these situations are covered – without wires attached.

New fire alarm kits

Sabre Fire and Security Ltd (www.sabre-fire.co.uk) has launched its new 2011 catalogue. This incorporates a wide range of new products, such as wireless fire detection equipment and contractor kits from Eurotech Fire Systems. The system uses an ‘open’ protocol, so is compatible with other fire alarm systems.

These new contractor kits, exclusively distributed by Sabre, are made in the UK and meet all relevant safety standards. They are ideal for professional users who demand quality, especially when it comes to safety.

The new kit is available in two-zone, four-zone and eight-zone versions, and it contains everything needed for a professional alarm system - additional components can be purchased separately.

Paul Hale, a director of Sabre comments: “In 2009/10 in the Highlands and Islands alone, there were over 2000 false alarms calls, an increase of 39% in five years. According to the Highlands and Islands fire board, the cost of attending false calls was around £235,000. It is therefore vitally important that we do not sacrifice quality for price.

“Furthermore, although our website has been very popular with contractors in 2010, we felt that our customers required the extra facility of a catalogue to enable them to get quick access to products and prices on the go.

“Our new contractor forum, which is being put together jointly by the Electrical Contractors Buying Group (www.ecbg.co.uk) and Sabre Fire and Security, enables contractors anywhere in the UK to discuss their problems with each other and our manufacturing partners”, Hale concludes

WIRING ACCESSORIES

less room for cabling.

Developments by manufacturers

can, of course, help overcome such issues. We

can, for instance, develop shallower back projections in accessories to free up more space in the back box. As an example, in a new range (Fig 3), sockets project just 15mm back from the faceplate and the wall switches by just 10mm. There is, however, an even more obvious answer. Why not just introduce a neutral loop connection in the switch itself so that a connector block is not needed?

Terminal answersWhile this is a major omission from wiring accessories there are a number of other improvements that can be made to make the contractor’s job simpler. Even details such as using a slotted screw head for good torque can make a big difference. Terminals should be in line, easily identifiable, orientated for best cable dressing and facing in the same direction. The terminal screws should be captive and backed out and there should be a positive wire end stop.

Most wiring accessory ranges also still use neon light indicators. Not only do these flicker and dim over time, but you need to install thin flying leads into one of the terminals. It is hard to know when the connection is made and it is too easy to over tighten and break the lead. Using an LED light indicator involves no additional installation and the light source remains bright, usually throughout the product’s lifetime.

Grid issuesAsk any electrician on site what they consider to be one of the most annoying areas of their job and many will answer installing grid products. The lack of cabling space and the number of wires to be positioned and terminated can make this particularly awkward and difficult.

There are a number of ways that good design (Fig 4) can make the installation of such products easier. The modules should be as shallow as possible to maximise cabling space in the back box. Also, why not clip them in from the front of the metal frame, rather than the back, to make them easier to fit and replace and to ensure that you cannot push them into the back box.

The wiring can also be simplified with the terminals all facing upwards for easier orientation with lead ins to guide the screwdriver, backed off screws held captive, wire end stops, plus clear white labelling off a dark grey background provided.

There’s always room for improvementThe lesson to be learnt from all of this is that, however long a product has been in the market, there is always room for improvement. While good aesthetics are vital, this is not a reason to ignore the development of installer friendly features. Some of these features make life easier and speed up installation, while you could argue that others further improve safety by ensuring termination of conductors.

We are all striving for the best looking easiest to install wiring accessory. By examining installation practice and asking installers, it is surprising just how much room for improvement there really is

40/100 Gb Ethernet cabling - a perfect storm?

8 March 2011 – London

9 March 2011 – Manchester

Multimode optical fibre cabling is faced with unparalleled challenges to support 40/100 Gb Ethernet. These present major difficulties in cabling design, installation and operation. Yet the more obvious move to dispense with multimode and opt for the comparatively simple singlemode solution is rejected by those highlighting the additional cost of the transmission equipment. Data centre (and backbone) cabling designers are faced with a complex decision-making balancing of capital outlay, operational expenditure, operational reliability and maintainability - while for installers the primary issues focus on testing, contamination management and possible contractual disputes. Two full-day seminars, entitled ‘40/100 Gb Ethernet cabling - a perfect storm - the challenges faced by designers, installers and users’ aims to provide a clear explanation of the key issues.

Legrand has just unveiled a new range of its Salamandre distribution trunking, which independent tests have shown to be 50% quicker to install than its predecessor when fitting length to length or length to fitting – which means a significant reduction in total installed cost. Fifty percent quicker is a lot, so we decided to put the product to the test. WireIN met up with Legrand’s Nigel Leaver to be put through its installation paces.

With a certain amount of pomp and ceremony, Nigel Leaver places a

large carrying case on the table in front of him and unfurls it to reveal two lengths of Legrand’s new Salamandre distribution trunking. Initially, the new product looks much like the old trunking that it is replacing, which Nigel has, with a little less ceremony, removed from a bag on the floor and placed beside the shiny new offering.

After voicing this opinion, Nigel points out that the new range has been designed to be fully compatible with the product it will eventually replace and so needed to match it in many ways. “The difference between the two,” he said, “is that the new trunking is packed full of innovative new developments that will help the installer every step of the way.”

What is the difference?So, what are these innovations and do they really help to deliver a product that is 50% quicker to fit?

The first thing to say from seeing the product demonstration is that the new trunking does feature many new developments – the company has really

PRODUCT FEATURE

tried to think of everything. For example, there is a double folded safety edge on the return of the trunking, which is safer for handling and cables. A great deal of thought has also gone into producing the multi-head shake-proof screws with their dome headed threads. These are there to help to protect the cables once they have been installed.

Speed of installation and, therefore, a reduction in total installed cost, is the rationale behind this new trunking, which becomes clear as we start to put the product through its paces – everything has been done to shave off every possible installation second.

Unlike the old trunking, the new coupler is external and supplied pre-fitted so that no time is wasted having to secure it to the trunking lengths, while the fact the screws are already in place certainly saves the installer from scrabbling around in the packaging in search of the correct screw for that particular fitting.

The benefit of the pre-fitted coupler on installation speed is further enhanced by the slotted ends on all lengths, which means that the new trunking only has to be slid over the pre-fitted coupler screw to fit one length to another.

Cutting even more time off the installation is the clever combination of a rapid fit cover and push-fit, spring loaded, quarter turn turnbuckles. The cover clips on and off the trunking with ease, while the turnbuckles do exactly what their description suggests – i.e. they only need to be pushed in to secure and then given a quarter turn to release. All this adds up to a quick fit and easy access to cables for maintenance.

Returning to the multi-head shake

proof screws with their dome headed threads, all are supplied assembled to the couplers and other fittings. This brings to a welcome end to the age old problem of missing bags of screws, while the fact they are all backed off ready to accept the next component ensures even quicker installation. Moreover, the screws’ multi-heads mean they can be tightened using either a screwdriver or spanner. This seemingly minor development none-the-less ensures that installers will be able to secure the screw no matter how tight a space the trunking is being installed in.

Simple is often bestComments Nigel: “Simple ideas are often the best, and this premise can be seen across the new range. Everything we’ve done with the new trunking has been aimed at reducing installation time and cost, but looking now at the end product it’s fair to say that all of them are very simple.

“It really was just a case of stripping our existing product right back, and then challenging every single aspect of it in order to unearth the simple, but highly significant room for improvement.”

As the stopwatch ticks onwards and it is a relative struggle to secure two lengths of Legrand’s old Salamandre trunking on the same table where we had put together the new trunking with ease and speed, it does seem that this new product really can save the electrical installation industry a significant amount of time and money.

SPECIAL FEATURE

Ian Gibson

With the recent extremely cold and snowy weather in mind, it is worth

reflecting on what exactly is meant by the word ‘weatherproof’. When you see terms such as ‘suitable for outdoor use’ or ‘weatherproof’, be very careful. You need to substantiate such terms, and when you specify conduit you should always consider the potential hazards to which it might be exposed.

Take flexible conduit as an example. It protects power and data cables. If you use it outdoors, then you must fully understand the local climate that you are specifying it for.

So what needs to be considered for ‘weatherproof’? Quite rightly most of us would refer to IP ratings, but this is not the only factor that needs considering. You should also think about resistance to ultraviolet (UV) degradation, corrosion and the product’s performance at different temperatures.

IP ratings firstStarting with IP ratings, the first number refers to protection against solid objects or dust ingress and the second to protection against water ingress. It should be a given that dust should not enter the conduit system in harmful quantities. Referring to Table 1 (opposite), the

conduit should have a minimum IP5X rating and preferably be IP6X – the ‘X’ meaning here that water ingress isn’t being considered – only dust ingress.

Water ingress could include rain, spray and possibly even shallow immersion. It could also cover capillary action and suction induced by the rise and fall of temperatures, although conduit systems are normally vented to atmosphere at one end, which allows the air inside to expand and contract.

IP tests to IEC EN 60529 indicate a system’s performance, but they are very short tests on samples that have been assembled under ideal conditions. Again, referring to Table 1, the duration of these tests are as follows:

IPX4 – Five minutes light sprayIPX5 – Three minutes medium sprayIPX6 – Three minutes high-pressure jetIPX7 – Thirty minutes immersed in one

metre of waterIPX8 – At a pressure and time stated

by the manufacturer (not often stated).

Note that the ‘X’ position above indicates that only water ingress is being considered, not dust ingress. If both are being considered, the product might be

rated (for example) as IP67.Care needs to be taken when referring

to an IP rating for moisture ingress. You should take a ‘belt and braces’ approach to prevent water ingress over a long period of time. If you don’t know the orientation of the fittings, then you should specify IPX6 or IPX7. If you are assembling the fittings on the underside of an enclosure then IPX5 or IPX6 may be suitable.

Resistance to UVUV radiation from the sun will also affect the performance of plastic materials by breaking down the long polymer chains. The result will be lower impact strength, less flexibility and lower fatigue life. The amount of UV radiation will depend on location, climate and altitude.

We always recommend a black product to resist UV as the carbon black inside the material protects the polymer chains. Check what the manufacturer means by ‘UV resistant’. Again, we generally add a certain amount of carbon black to ensure UV resistance in products that can be used for anywhere in the world. Manufacturers can make other colours UV resistant by adding a chemical UV resistant additive, but this is more expensive than adding carbon black. If you are in any doubt, ask for test reports showing a product’s UV resistance.

CorrosionIf you are using metal conduit and/or fittings, then corrosion could be an

issue. We would not recommend using galvanised steel outdoors, because it will rust. Coated steel conduits are suitable as long as the IP rating is sufficient to prevent water getting into the conduit.

Nickel-plated brass fittings will discolour through oxidisation over time (and much more quickly in coastal areas). If you need to use steel in marine environments, then Grade 316 stainless is suitable.

TemperatureFinally, consider the affects of temperature. Generally the maximum temperature reached because of the weather is not an issue. You should check the minimum temperature that the conduit may need to operate in however, to prevent damage by impact or bending during installation and use.

Similar to most reputable conduit manufacturers, we have certain products that are suitable for outdoor use. One example can be used with stainless steel fittings to give an IP rating of up to 69k and can be used for temperatures from -20oC to 105 oC. Another range extends this to between -45 oC to 135oC.

In conclusionIt is unlikely that any organisation will introduce a standard for the term ‘weatherproof’, so you need to make your own informed decision and ask the right questions. We hope this article helps, but if in any doubt, seek the advice of a reputable manufacturer

What exactly do you mean by that word ‘weatherproof’ with conduit in mind? Before specifying outdoor protection make sure that you define exactly what you require, states Ian Gibson:

Table 1 shows ingress protection ratings to BS EN 60529 for solid objects, dusts and water.

When you see terms such as ‘suitable for outdoor use’ or ‘weatherproof’, be very careful. It must be right for the conduit in applications such as this CCTV security installation to work properly.

Turn off that power!An East Lothian sawmill company has been fined after an employee’s leg was seriously injured when he was cutting wood. He had been using a drop sorter machine. When two planks became stuck, the employee climbed onto the conveyor belt, kicked the wood that was causing the jam, and unblocked the machine. However, because the power had not been turned off, as soon as he dislodged the wood, it re-started immediately at full speed.

The employee’s leg was dragged into the machine, where it became trapped. The machine stopped running seconds later, while the main remained trapped in the machine for about one and half hours and had to be freed by firefighters. His left leg was broken in

Worker broke back in fall after electric shockA subcontractor fell over five metres from a crane ladder after suffering an electric shock at one of the UK’s largest timber merchants. Mechanical fitter, David Minor, suffered a number of injuries, including a broken vertebra, as a result of the incident. The subcontractor was fixing an overhead crane system. Climbing a ladder to access the crane, he made contact with a three-phase 415V live conductor. He fell 18ft and landed on the concrete floor, sustaining a fractured vertebra, a broken ankle, smashed heel, and burns to his hands.

The conductor touched was the main power channel to the overhead crane. It carried electricity but was not marked and had not been isolated prior to work commencing.

The company concerned admitted breaching Regulation 4(3) of the Electricity at Work Regulations 1989, failing to ensure work was carried out in such a manner as to not give rise to danger. The firm was fined £5,000 and ordered to pay £4,344.70 in costs.

three places and he suffered significant nerve damage.

The Health and Safety Executive (HSE) that the company involved had failed to assess the risks involved and there was inadequate guarding in place. The company was fined £20,000. However, the machine had not been turned off. If a proper emergency stop button had been fitted and used, the accident might not have happened. Emergency stop systems that detect machine jams are also available.

The HSE (www.hse.gov.uk) is Britain’s national regulator for workplace health and safety. In Scotland, the Crown Office and Procurator Fiscal Service has sole responsibility for the raising of criminal proceedings for breaches of health and safety legislation.

Scottish power fined after electricity cable deathThe death of a young man who spent his last moments warning motorists about a live electricity cable has prompted the prosecution of Scottish Power UK. The Health and Safety Executive (HSE) has taken action against Scottish Power after a 20-year-old man was killed in Shropshire. The energy provider was fined £130,000 and ordered to pay £48,000 costs after pleading guilty to contravening Regulation 4(2) of the Electricity at Work Regulations 1989.

The man was killed after he went out on to a road to warn motorists that a power cable had sagged because of high winds. The cable was then struck by a passing van and fell on to the road where a car drove over it, causing it to fly up into the air. The cable hit the man in the face, seriously injuring him. He was taken to hospital but died eight days later from the injuries caused by being struck by the cable, rather than by electric shock.

An HSE investigation showed the cable had been attached to a wooden block on the side of nearby Holly Farm House. An HSE specialist electrical inspector said that the block was found to be partially rotten and the deterioration led to the cable becoming detached. Since the incident Scottish Power has removed this type of fixing arrangement from its network and now uses more effective metal brackets.

RoSPA welcomes daylight saving bill successThe Royal Society for the Prevention of Accidents (RoSPA - www.rospa.com) has welcomed the recent House of Commons vote in favour of the Daylight Saving Bill. The Bill proposes a cross-departmental analysis of the potential benefits of moving to Single/Double Summer Time (GMT+1 in winter, GMT+2 in summer) - which, in turn, could lead to a three-year trial. The Bill now goes through to the next Parliamentary stage.

RoSPA, which has been campaigning on this issue for decades, joined 10:10’s Lighter Later coalition in March. Since then, the cause has attracted tens of thousands of supporters. Whether this is quite such a popular plan in Scotland is another matter!

Take extra precautions in freezing conditionsThe Health and Safety Authority in Ireland (HAS - www.hsa.ie) was urging employers and workers to take care in the recent icy conditions, which made walking (and driving) surfaces treacherous. The Authority asked employers to be particularly careful and to ensure that their workplaces are safe for everyone - employees, visitors and customers.

Air routing for Rittal enclosure cooling units

When using Rittal’s TopTherm-Plus roof-mounted cooling units, the air duct system should be used to ensure proper routing of the chilled air within the enclosure. Cold air can be targeted directly to specific enclosure areas, ensuring that chilled air is not blown directly at the exhaust of hot components. The air duct system can also reduce risk of ‘short circuits’ in the air supply that can compromise cooling unit efficiency.

Sangamo motion/daylight detection sensorsSangamo’s microwave sensors can be used in a wide variety of light fittings. Both motion and daylight detection ensures that lights only switch on and off when necessary, so energy savings can be made, but comfort is not compromised. If lights cannot be switched off completely, the microwave sensors can allow light ballasts to dim to an appropriate level - reducing energy consumption yet maintaining lighting in vulnerable areas.
