Variable Frequency Drives (VFD’s) 1. Change the name from Power Logix to Power Flex Series (Allen Bradley) See pg. IX-

16 & 49


14

Rubber Matting 1. What is considered OSHA approved

matting? Electrical rated matting that meets the Type II ASTM D178 Standard. See pg.

IX-10, 35, & 39


15

Conduits 1. Painted red in pump station per request of

the owner (Does not apply for PVC Coated Rigid). Refer to Section X Coatings manual page 148. See pg. IX-21


16

MCC/Switchgear Fasteners 1. Provide extra fasteners when ordering gear

(spare parts). See pg. IX-33 and IX-36


17

Analyzers/Monitors 1. Added E&H probe for Incinerator scrubber

water (process pH); Specific applications at Treatment Plants See pg. IX-67


18

Level Sensing Systems Bubbler 1. Remove Bell & Gossett as Mfr. 2. Add model 3HBB-10-M300 AX (Dual Head

Air Compressor) or equal See pg. IX-15

3. Separate circuit for each compressor (Panel schedule)


19

Voltage Test Points Mfr. Safeside See pg. IX-7 and IX-39


20

DIN Rail 1. Add Panduit Panduct DIN Rail Wiring Duct See pg. IX-5


21



22


Pump Station section 16- provide one weatherproof (WP/Watertight) receptacle with lockable cover on the exterior wall of the pump station on a separate circuit; separately switched -> must not be hot at all times. See pg. IX-25

Provide high level float ball for alarms See pg. IX-15

Provide Intrinsically safe barriers See pg. IX-16


23

Add Remote Switch Operator to open/close main circuit breaker outside of the arc flash boundary. See pg. IX-32


24


25

Add ARMS “Arms Reduction Maintenance Switch or Equal; When activated downstream incident energy levels will be reduced. See pg. IX-32

Add LSI or LSIG (>=1000A) Electronic Trip Units See pg. IX-33


26

Add Short Circuit, Coordination, and Arc Flash requirements to specifications (Arc Flash calculations must be performed for both Utility bus and Generator bus); A label must be added to the generator breaker. See pg.

IX-31


27

Push-buttons, selector switches, etc. must be NEMA rated only (Some Mfr. Have both NEMA/IEC ratings on components). See pg.

IX-34 & 37


28

ETM Add Mfr. Crompton and ENB Elapsed Time Meters; Yokogawa UL certification in question. See pg. IX-65


29

Surge Protection Devices Remove SPD Type IC4/IC6 Surge Protectors - Don’t use DC powered surge protection on

field devices (4~20mA). - Don’t use AC powered surge protection for

field devices. - All SPD should be installed at the incoming

power section of the gear.


30

Splicing 1. No splicing allowed on HRSD projects

without approval from Engineer/Owner. 2. No splicing in man-holes 3. If granted approval, splicing must be perform

by certified splicer. 4. May require above ground installation.


31

Variable Frequency Drives- New circuit diagram


32

Tegam Windows • J. Matt Ferguson • DRISCOLL AUTOMATIC • 918/663-6625 – Main • 918/664-0930 – Fax • 918/636-3500 – Cell • P.O. Box 52583 • Tulsa, OK 74152


33

Tegam Windows- AW1012 Can be eliminated if installed in condition spaced.


34

Conduit schedule vs. Circuit Method Some consultants method of design does not

use conduit schedules so individual conduit tag numbers do not exist. The one line diagrams use circuit numbers. For power circuits (except for lighting and receptacles circuits) a conduit is dedicated to that circuit. For control and instrumentation circuits; They often have multiple circuits in a common conduit.


35

Labeling Method (phenolic labels) – White lettering on Black background. See pg. IX-30,

33, & 36


36

Actuators EIM actuators- verify use of proper voltage 120 vs. 480V -Use proper control boards based upon required voltage.


37

Polaris Style Connectors not preferred ; T leads to motor (rarely used); Prefer lugs


38

Pump Station ATS Push to test function; manually initiate 2 hour test to start generator and assume load. After two hours the system automatically returns to utility source if available. Note: This is not an exercise function.

Remove Mfrs. Cummins and SQD; Specify Eaton or ASCO. See pg. IX-11


39

Locate HOA switch at drives for variable

speed applications Locate HOA switch at pump for constant

speed applications.


40

Reoccurring Themes


41

Load Bank Test Boxes 1. Fabrication –UL Shop Harper Sheet Metal Richmond VA 23224 (804) 233-6550


42

Reoccurring Themes

o Load bank test boxes – Eaton and other Mfrs. have similar connection boxes; However HRSD standardized the use of Leviton Connectors, due to Operation’s wire spool trailers having Leviton mating connectors.

o Other products utilize Hubbell connectors. The Mfrs. would like for HRSD to use Hubbell connectors to prevent the modification of their UL listing.


43

o Shop Drawing Submittal/Approval Process o HRSD Electrical Staff would desire access to a file

storage area, to review submittals in parallel with consultants, in an effort to streamline the overall process.

o Secure As-Builts/ Record Drawings before closeout of Project.

o Functionals and P&ID’s o Interposing Relays o DCU Power Supplies/Isolation transformer o Arc Flash Mitigation (> 40 cal/cm2)– Design, SC,

Coordination, AF analysis, and labeling.


44

o Arc Flash – Breaker/Relay settings for contractors.

o Variable Frequency Drives (VFD’s) o Long term maintenance plan at substantial

completion. o Rice Rule o MOPO o Generator/paralleling gear (block load or soft

load)


45

o 100 ms closed transition test and 225 ms breaker timing test

o NFPA 820 o Energy Conservation


46

o Dominion Virginia Power Interconnection Agreement


47

New Electrical Services 1. Site Plan 2. Load Letter 3. Power Riser 4. Sequence of Operation 5. Access Facility Charges – Right size

equipment


48


49


50

Lighting Quick strike preferred for metal halide See pg.

IX-20 and IX-52

LED preferred


51

Wire Stranded wire only (No solid wire allowed). Sometimes solid wire for smaller No. gauge

wire will be specified. See pg. IX-23 and IX-

57


52

Some other beneficial practices:

Separate Electrical Meetings Checklist for QA/QC Involve HRSD with Electrical Inspections Verify loop checks


53

Turnover file, cables, hardware, and software to HRSD.

HRSD needs ownership to any processor based controls and/or equipment.

No proprietary programs that would not grant HRSD access to modify and/or troubleshoot.


54

o Scheduling of Training for Equipment or New systems.

o Generator load bank test must witnessed by HRSD EEM and Automotive Representative.

o Excavation around live energized lines. Hand dig or pot hole to locate potential utility conflicts.
