INPUT WIRE SIZE, GROUNDING AND OUTPUT WIRING
A. Conduit should be used for both input and output wiring.
B. Input wire size is based on the NEC table 310.16. Specifying not more than 3 connections in a raceway
based on an ambient of 30°C and wire rated for 90°C (Note: amperages will need to be adjusted for
40° C ambient applications).
C. Input phase conductors are terminated directly to the input circuit breaker terminals.
Wire range:
208 VAC
240 VAC
480 VAC
600 VAC
D. Input ground lug TA-250, max wire range 6 AWG - 250 MCM one piece.
E. Output is a 4 wire (5 including ground). If four (4) current carrying conductors are used in a raceway
the neutral is assumed to be current carrying and the wire must be de-rated as indicated in table 310.6
on the NEC.
Example: 1.
2.
3.
NOTE: Installation is subject to local codes - verify with a local electrical inspector.
F. All output ground and neutral terminals are copper bus bars w/ two holes. Double bolted lug are
recommended. Manufactured by Burndy
RECOMMENDED LUGS: Double bolted type as supplied by Burndy Copper Compression lug, 2 hole
Type YA, ¼" stud, ¾" spacing.
YA6CL-2TC14E2 #6 wire
YA1CL-2TC14E2 #1 wire
YA27L-2TC14E2 #3/0 wire
Output connections are made directly to the output breaker(s) and output neutral and ground lugs
provided. The load current is not to exceed 80% of the output breaker(s) rating, and not to exceed
the rated total current.

300 Amp breaker #1 AWG to #600 KCMIL
250 Amp breaker #3/0 AWG to #350 KCMIL
150 Amp breaker #14 AWG to #3/0 AWG
100 Amp breaker #14 AWG to #3/0 AWG
Assume #10 wire max current = 25 Amps.
Multiply 25 x .8 = 20
20 Amps is max current for #10 wire in a raceway with 4 conductors.
