31 S&P Electrical Workshop 2016Splicing No splicing allowed on HRSD projects without approval from Engineer/Owner. No splicing in man-holes If granted approval, splicing must be perform by certified splicer. May require above ground installation.

32 S&P Electrical Workshop 2016Variable Frequency Drives- New circuit diagram

33 S&P Electrical Workshop 2016Tegam Windows J. Matt Ferguson  DRISCOLL AUTOMATIC  918/ – Main  918/ – Fax  918/ – Cell  P.O. Box  52583  Tulsa, OK 74152

34 S&P Electrical Workshop 2016Tegam Windows- AW1012 Can be eliminated if installed in condition spaced. 

35 S&P Electrical Workshop 2016Conduit 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.

36 S&P Electrical Workshop 2016Labeling Method (phenolic labels) – White lettering on Black background. See pg. IX-30, 33, & 36

37 S&P Electrical Workshop 2016Actuators EIM actuators- verify use of proper voltage 120 vs. 480V -Use proper control boards based upon required voltage.

38 S&P Electrical Workshop 2016Polaris Style Connectors not preferred ; T leads to motor (rarely used); Prefer lugs

39 S&P Electrical Workshop 2016Pump 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

40 S&P Electrical Workshop 2016Locate HOA switch at drives for variable speed applications Locate HOA switch at pump for constant speed applications.

41 S&P Electrical Workshop 2016Reoccurring Themes

42 S&P Electrical Workshop 2016Load Bank Test Boxes Fabrication –UL Shop Harper Sheet Metal Richmond VA (804)

43 S&P Electrical Workshop 2016Reoccurring Themes 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. Other products utilize Hubbell connectors. The Mfrs. would like for HRSD to use Hubbell connectors to prevent the modification of their UL listing.

44 S&P Electrical Workshop 2016Shop Drawing Submittal/Approval Process 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. Secure As-Builts/ Record Drawings before closeout of Project. Functionals and P&ID’s Interposing Relays DCU Power Supplies/Isolation transformer Arc Flash Mitigation (> 40 cal/cm2)– Design, SC, Coordination, AF analysis, and labeling.

45 S&P Electrical Workshop 2016Arc Flash – Breaker/Relay settings for contractors. Variable Frequency Drives (VFD’s) Long term maintenance plan at substantial completion. Rice Rule MOPO Generator/paralleling gear (block load or soft load)

46 S&P Electrical Workshop 2016100 ms closed transition test and 225 ms breaker timing test NFPA 820 Energy Conservation

47 S&P Electrical Workshop 2016Dominion Virginia Power Interconnection Agreement

48 S&P Electrical Workshop 2016New Electrical Services Site Plan Load Letter Power Riser Sequence of Operation Access Facility Charges – Right size equipment

49 S&P Electrical Workshop 2016

50 S&P Electrical Workshop 2016

51 S&P Electrical Workshop 2016Lighting Quick strike preferred for metal halide See pg. IX-20 and IX-52 LED preferred

52 S&P Electrical Workshop 2016Wire 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

53 S&P Electrical Workshop 2016Some other beneficial practices: Separate Electrical Meetings Checklist for QA/QC Involve HRSD with Electrical Inspections Verify loop checks

54 S&P Electrical Workshop 2016Turnover 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.

55 S&P Electrical Workshop 2016Scheduling of Training for Equipment or New systems. Generator load bank test must witnessed by HRSD EEM and Automotive Representative. Excavation around live energized lines. Hand dig or pot hole to locate potential utility conflicts.
