DETAIL NOTES
A SECONDARY CONDUCTORS SHALL ALWAYS BE TERMINATED IN AN
OVERCURRENT PROTECTION DEVICE, PER NEC 240.21(C)(1). THE
SOLE EXCEPTIONS ARE SYSTEMS WITH A SINGLE PHASE, 2 WIRE
SECONDARY AND SYSTEMS WITH 3 PHASE, 3 WIRE, DELTA-DELTA
CONNECTED TRANSFORMER.
GROUNDING ELECTRODE CONDUCTOR
(GEC), SIZED PER NEC 250.66. IF USING
METAL CONDUIT, THE CONDUCTOR
SHALL BE BARE COPPER AND SHALL BE
BONDED TO CONDUIT USING BONDING
BUSHINGS OR OTHER APPROPRIATE
FITTINGS AT BOTH ENDS OF THE
CONDUIT.
MAIN BONDING JUMPER,
SIZED PER NEC 250.28(D)(1).
GRIND PAINT OFF BEFORE BOLTING
LUG TO TRANSFORMER CASE.
GEC CONDUIT. PVC IS PREFERRED,
EMT IS ACCEPTABLE.
ADJUSTABLE PRIMARY TRANSFORMER
TAPS. REFER TO TRANSFORMER COVER
OR MANUFACTURER INSTRUCTIONS TO
DETERMINE THE PROPER TAP TO USE,
BASED ON THE AVAILABLE PRIMARY
VOLTAGE.
ALL CONDUITS WITH CONDUCTORS
#4 AWG AND LARGER SHALL HAVE
INSULATING BUSHINGS ON
CONNECTORS. SECONDARY
CONDUITS SHALL HAVE BONDING
BUSHINGS INSTALLED.
EQUIPMENT BONDING JUMPER FOR
ALL SECONDARY CONDUITS SHALL
BE SIZED PER NEC 250.102(C).
B THE SECONDARY CONDUCTORS SHALL NOT EXCEED 25' IN LENGTH
BEFORE TERMINATING IN AN OVERCURRENT PROTECTION DEVICE,
PER NEC 240.21(C)(6). THESE CONDUCTORS SHALL BE SIZED FOR
THE FULL AMPACITY OF THE OVERCURRENT PROTECTION DEVICE.
C THE SECONDARY CONDUCTORS SHALL HAVE A SUPPLY-SIDE
BONDING JUMPER IN EACH RACEWAY, WHERE THE MAIN(SYSTEM)
BONDING JUMPER IS LOCATED AT THE SOURCE OF THE SEPERATELY
DERIVED SYSTEM, AND THE FIRST MEANS OF DISCONNECT IS IN A
SEPERATE ENCLOSURE, PER NEC 250.30(A)(2)(a). PER NEC 250.102(C)
(1) & NEC 250.102(C)(2), THIS CONDUCTOR SHALL BE BASED ON THE
SIZE OF THE UNGROUNDED CONDUCTORS IN EACH RACEWAY OR
CABLE, NOT THE SUM OF ALL UNGROUNDED CONDUCTORS.

DISTRIBUTION - GENERAL NOTES
A CONDUIT SIZES ARE MINIMUM GUIDELINES, AND MAY NOT COVER ALL
INSTALLATIONS. IT IS ACCEPTABLE TO ADJUST CONDUIT SIZE BASED ON
RACEWAY TYPE, PER NEC REQUIREMENTS.
B EACH PARALLEL RUN SHALL BE ELECTRICALLY SIMILAR, AND CONTAIN THE
SAME NUMBER OF CONDUCTORS / CABLES. COMPLY WITH ALL NEC
REQUIREMENTS FOR PARALLEL INSTALLATIONS. (NEC ART. 310.10(H))
C SEPARATELY DERIVED SYSTEMS SHALL HAVE A SUPPLY SIDE BONDING
JUMPER INSTALLED PER NEC ART. 250.102(C), WHERE APPLICABLE. (NEC
ART. 250.30(A)(2))
D EC SHALL COORDINATE THE AIC RATINGS OF ALL EQUIPMENT AND VERIFY
THAT IT IS CORRECT, PRIOR TO PURCHASE / INSTALLATION OF EQUIPMENT.
SERIES RATINGS SHALL NOT BE ALLOWED FOR EQUIPMENT SERVING
MOTOR LOADS. (NEC ART. 240.86(C))
E EMERGENCY SYSTEMS SHALL BE ISOLATED AND MARKED AS REQUIRED BY
CODE. (NEC ART. 700.7(A) & NEC ART. 700.10)
F WHERE GROUND FAULT PROTECTION IS REQUIRED, A FUNCTIONAL
PERFORMANCE VERIFICATION TEST SHALL BE PERFORMED AFTER THE
EQUIPMENT IS INSTALLED, PRIOR TO BEING ENERGIZED BY THE SOURCE.
UTILIZING THE "PUSH TO TRIP" FEATURE IS NOT ALLOWED. TESTING SHALL
BE PERFORMED UTILIZING A PRIMARY CURRENT INJECTION TEST SET. THE
TESTING RESULTS SHALL BE SUBMITTED TO THE ENGINEER OF RECORD
AND BE MADE AVAILABLE UPON REQUEST TO THE AHJ. IT IS THE
RESPONSIBILITY OF THE EC TO DETERMINE IF THIRD PARTY TESTING IS
REQUIRED BY THE AHJ. (NEC ART. 230.95)
