TRANSCRIPT

  • Engr. HIPOLITO A. LEONCIO Chairman, Electrical Safety and ESEA committee

  • ELECTRICAL INSPECTION STRATEGY AND GUIDE

    Republic Act 7920

    An act providing for a more responsive and comprehensive regulation for the practice, licensing, and regulation of electrical engineers and electricians

  • STRATEGIC SOLUTIONS The Philippine Electrical code

    is used nationally as the

    basis for safeguarding

    persons, buildings and its

    contents from hazards that

    may arise from the use of

    electricity.

    This code contains provisions

    which is considered

    necessary for safety and thus

    is used as basis for the legal

    enforcement agency in the

    government regarding

    electrical installation

  • Electrical

    Safety

    Enforcement and

    Awareness

  • February 10, 2011 MOA Signing for

    the 3-year Electrical Safety Enforcement

    and Awareness (ESEA) Campaign Project

    May 21, 2011 Launching of ESEA at

    the Institute of Integrated Electrical

    Engineers of the Philippines, Inc Head

    Office.

    ESEA Profile

  • ESEA Profile June 27, 2011 President Aquino signed

    Proclamation No. 193 declaring the Month of

    May of every year thereof as the Electrical

    Safety Month.

    May 24, 2013 Addendum to the MOA was

    signed at Taal Vista Hotel, Tagaytay City. This is

    to continue the campaign on electrical Safety

  • DECLARING THE MONTH OF MAY OF EVERY YEAR AS THE

    ELECTRICAL SAFETY MONTH

    WHEREAS, many lives and

    properties are lost due to fires

    and electrocution

    PRESIDENTIAL PROCLAMATION NO. 193

  • WHEREAS, most of these fires and incidents of electrocution are attributed to faulty electrical wiring

    PRESIDENTIAL PROCLAMATION NO. 193

  • WHEREAS, economic losses brought about by

    fires contribute to

    reduced productivity and

    therefore affect the

    economy of the country

    PRESIDENTIAL PROCLAMATION NO. 193

  • PRESIDENTIAL PROCLAMATION NO. 193

    WHEREAS, there is a real need to increase public awareness on

    electrical safety and educate our

    people in the safe use of

    electricity.

  • MISSION - To ensure ESEA is

    properly enforced through improving

    local inspectors capacity and to

    increase the publics awareness on

    electrical safety.

    ESEA Profile

  • VISION - To be a major campaign that leads the public towards an electrically safe environment.

  • Electricity- The Dangers 12,301 Fires recorded nationwide- source BFP as of

    2013

  • WHAT IS AN ELECTRICAL INSPECTION & AUDIT?

    An electrical audit is a thorough survey/ inspection, review and evaluation of an electrical system which is already in operation for several years.

  • WHAT IS THE PURPOSE OF AN ELECTRICAL INSPECTION &

    AUDIT? The purpose of an electrical safety inspection or audit is to identify potentially hazardous electrical situations and provide corrective actions for these situation.

  • OBJECTIVES of ELECTRICAL

    INSPECTION & AUDIT - 1

    # 1. Determine compliance of the electrical system to electrical safety, viz-a-viz:

    - Philippine Electrical Code (Part I & II)

    - National Electrical Code - NFPA 70E - NFPA 70B - OSHA 1910.331-335

    - Other Electrical Codes (IEC)

  • OBJECTIVES OF AN ELECTRICAL

    INSPECTION & AUDIT 2,3,4

    #2. Review and provide corrective actions for

    safe electrical work processes.

    # 3. Review and provide corrective measures for electrical maintenance tools.

    # 4. Identify efficient measures and potential cost savings through modifications/ improvements in the electrical system.

  • So what would be the samples of electrical violations or errors that you should be mindful of when you do your electrical audit/ inspections?

  • 1. THE USE OF HIGHER RATED CIRCUIT PROTECTION . . . THIS IS A RAMPANT VIOLATION!

  • 1-A. ANOTHER CASE OF USING VERY HIGH RATING OF PROTECTION..

    AS INSPECTED IN 2011, THE SIZE OF THIS SERVICE ENTRANCE FEEDER IS 2 14 SQUARE MM IN A PVC CONDUIT, SO THAT THE ALLOWABLE AMPACITY IS

    70 AMPERES BUT THE PROTECTION IS 200-AMPERE FUSES!

    THE IIEE ESC/ESEA VOLUNTEER TEAM IN 2012 REPLACED IT WITH 100-AMPERE FUSES.

  • Ex.2.D UNINTENTIONALLY CREATING STRAY CURRENTS/ localized heating

    . . THIS WAS DISCOVERED JUST RECENTLY ON A 40-STOREY TOWER ELSEWHERE IN A CENTRAL BUSINESS DISTRICT IN METRO MANILA!

    NOTE THE SAME PHASE CONDUCTORS IN SAME RS CONDUIT. HOW COULD THE SITE ELECTRICAL ENGINEER AND/OR ELECTRICAL FOREMAN MADE THE OVERSIGHT!

  • 3. INADEQUATE EQUIPMENT GROUNDING . .

    WHAT WOULD BE THE MAXIMUM GROUNDING RESISTANCE? IS IT 25 OHMS?5 OHMS?1 OHM? THE LOWER THE VALUE, THE SAFER! WHY? GROUND FAULT CURRENT SEEKS THE PATH OF LOWER RESISTANCE.

  • 4. NOT USING GROUNDING TYPE CONVENIENCE OUTLETS . . .

  • 5. NOT USING GFCI DEVICE FOR CIRCUITS IN DAMP LOCATIONS OR EXTERIOR AREAS . .

  • 6. NOT CHECKING THE BUS BAR CAPACITY OF THE PANEL BOARDS/ BUS BAR GUTTERS . .

  • 7. FAILURE TO TEST COMPLETELY BEFORE ENERGIZATION

    AFTER A PROLONGED SHUTDOWN OF A SWITCHGEAR, A DANGEROUS ARC FLASH FAULT BETWEEN PHASES MAY RESULT AFTER ENERGIZATION OF THE BUS BARS!

    THIS MAY HAPPEN WHEN THERE IS A FAILURE TO DETERMINE THE INSULATION RESISTANCE OF THE ENCLOSED

    BUS BARS.

    AFTER A PROLONGED SHUTDOWN ON A HUMID DAY, MOISTURE MAY OCCUR DUE TO CONDENSATION INSIDE THE SWITCHGEAR.

    WARNING: ALWAYS MEGGER TEST CIRCUIT BREAKERS, BUS BARS, CABLE FEEDERS BEFORE ENERGIZATION!

    THE HIGHER THE MEGGER READING, THE SAFER!

  • 8. USING IMPROPER SPLICES

  • 9. NOT USING SEAL FITTINGS IN HAZARDOUS LOCATIONS

    NOTE THAT THERE ARE NO TYPE EYS CONDULET SEAL FITTINGS ON THE CONDUITS WITHIN 150MM FROM THE

    SWITCH BOXES.

    IN CLASSIFIED LOCATIONS, THE CONDUIT SEAL WOULD

    PREVENT THE ENTRY OF FLAMABLE GASES OR VAPORS TO THE SWITCHES WHICH ARE

    POSSIBLE SOURCES OF A SPARK.

  • 10. LACK OF SUPERVISION DURING CONSTRUCTION. . .

    THESE INAPPROPRIATELY/POORLY SPLICED WIRES INSIDE A BADLY BURNT FLEXIBLE PVC CONDUIT. THE ELECTRICAL SUPERVISOR/FOREMAN MISSED THIS.

  • 11. TEMPORARY WIRING ALLOWED TO BECOME TEMPORARY-PERMANENT

    THE FLYING WIRES/CABLES WHICH INCLUDE POWER & COMMUNICA-TION LINES ARE INSTALLED TEMPORARILY.. UNTIL AN UNTOWARD INCIDENT HAPPEN AGGRAVATING MATTERS ACCIDENTS.

  • 12. NOT USING SEAL FITTINGS IN HAZARDOUS LOCATIONS

    NOTE THAT THERE ARE NO TYPE EYS CONDULET SEAL

    FITTINGS ON THE CONDUITS WITHIN 150MM FROM THE

    SWITCH BOXES.

    IN CLASSIFIED LOCATIONS, THE CONDUIT SEAL WOULD

    PREVENT THE ENTRY OF FLAMABLE GASES OR VAPORS TO THE SWITCHES WHICH ARE

    POSSIBLE SOURCES OF A SPARK.

  • 13.LACK OF SAFETY SENSE

    NOTICE THE SERVICE ENTRANCE WIRES, NO ENTRANCE CAP OR DRIP LOOP THIS ALLOWS WATER TO ENTER CONDUIT AND MAY EVEN REACH PANELBOARD INSIDE, CAUSE DAMAGE, OR GROUND FAULT. THERE IS ALSO NO GROUND WIRE.

  • 14.NOT USING BOLT-ON TYPE MAINS

    THE 60A PANEL MAIN CBs ARE PLUG-IN TYPE, SHOULD BE BOLT-ON TYPE..

    THE PLUG-IN MAINS WILL RESULT TO LOOSE CONNECTION, LOCALIZE HEATING..

  • 15. LACK OF MAINTENANCE

    REGULAR CLEANING

    REQUIRED.

    CABLE

    TERMINATIONS

    ARE VIOLATIONS.

    COLOR CODING OF

    WIRES MUST BE

    FOLLOWED.

  • 16. JUNCTION BOX COVER MISSING ..

    THE ABSENCE OF THE COVER FOR THE JUNCTION BOX EXPOSES THE CONDUCTORS NOT ONLY TO WATER BUT ALSO TO THE ULTRA-VIOLET (UV) RAYS OF THE SUN, CAUSING THE DETERIORATION OF THE INSULATION OF

    THE CONDUCTORS FASTER.

  • 17. Panel Cover & Power CBs Not Fitted Properly

    In a big manufacturing plant, during the retrofitting or replacement of the main circuit breaker of the Low Voltage Switchgear, the panel opening is so big where in there is a large clearance between the front face of new power breaker and the panel opening. This may allow foreign bodies such as dust, and even live creatures to possibly enter inside the switchgear and cause a shutdown. A control wire is even left not tied properly.

  • 18. Old Fused Disconnects Still in Use?

    The use of old fused disconnect switches where in the load side feeder wires are

    too small in their ampacities as matched to the rating of the fuses. The fuses may protect

    the small wires from high magnitude short circuit current but not on an overload current

    or during a low magnitude line-to-ground fault. These

    installations must be replaced with bus bar type panel board

    of power distribution to various load circuits.

  • 19. Cables Not Provided w/ Raceways..

    Would you believe that this kind of cable installation still exists? If you are the electrical practitioner assigned to supervise the electrical works, how would you have provided for a better job?By providing flexible metallic conduits?By a cable duct?Or by extending the cable trench?

  • 20. POOR VENTILATION FOR HEAT GENERATING EQUIPMENT

    THE TRANSFORMER BELOW WHICH WAS INSTALLED INSIDE A CABINET THAT IS NOT ADEQUATELY VENTILATED OR NOT PROVIDED WITH LOUVERS SHOWS SIGNS OF EXCESSIVE HEAT BEING DISSIPATED. IT WAS SOON DAMAGED

  • AS-BUILT PLANS After your thorough electrical inspection & audit,

    you will now prepare/ update your electrical drawings:

    * Lighting Layouts * Power Layouts * Panel Arrangements * Single Line Diagram/ Riser Diagram * Load Schedules and Computations * Service Entrance

    * Substation * Meter Center * Grounding system * Lightning Protection system * Other electrical details of

    the electrical system

    Note down all observations of non-compliance/ Code violations, unsafe situations, inefficient

    system/ equipment, etc
