25
Add ARMS “Arms Reduction Maintenance Switch or Equal; When activated downstream incident energy levels will be reduced. See pg. IX-32
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
S&P Electrical Workshop 2016
27

S&P Electrical Workshop 2016
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.
S&P Electrical Workshop 2016
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.

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
S&P Electrical Workshop 2016
33
Tegam Windows- AW1012 Can be eliminated if installed in condition spaced.
S&P Electrical Workshop 2016
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.
S&P Electrical Workshop 2016
35
Labeling Method (phenolic labels) – White lettering on Black background. See pg. IX-30,
33, & 36
S&P Electrical Workshop 2016
36
Actuators EIM actuators- verify use of proper voltage 120 vs. 480V -Use proper control boards based upon required voltage.
S&P Electrical Workshop 2016
37
Polaris Style Connectors not preferred ; T leads to motor (rarely used); Prefer lugs
S&P Electrical Workshop 2016
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
S&P Electrical Workshop 2016
39
Locate HOA switch at drives for variable
speed applications Locate HOA switch at pump for constant
speed applications.

Load Bank Test Boxes 1. Fabrication –UL Shop Harper Sheet Metal Richmond VA 23224 (804) 233-6550
S&P Electrical Workshop 2016
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.
S&P Electrical Workshop 2016
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.
S&P Electrical Workshop 2016
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)
S&P Electrical Workshop 2016
45
o 100 ms closed transition test and 225 ms breaker timing test
o NFPA 820 o Energy Conservation
S&P Electrical Workshop 2016

New Electrical Services 1. Site Plan 2. Load Letter 3. Power Riser 4. Sequence of Operation 5. Access Facility Charges – Right size
equipment
S&P Electrical Workshop 2016
48
Lighting Quick strike preferred for metal halide See pg.
IX-20 and IX-52
LED preferred
S&P Electrical Workshop 2016
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
S&P Electrical Workshop 2016
52
Some other beneficial practices:
Separate Electrical Meetings Checklist for QA/QC Involve HRSD with Electrical Inspections Verify loop checks
S&P Electrical Workshop 2016
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.
