1
Wire sizes based on recommendations of the American National Standards Institute (ANSI) approved
National Fire Protection Association's (NFPA) National Electrical Code (NEC). Table 310.15 (B) (16) for
copper wire at 90°C conductor temperature. For operation in countries where the NEC is not recognized,
follow applicable codes.
2
Recommended wire sizes are sufficient to restrict voltage drop to 1.0 volt or less at listed branch current for
the loop lengths shown. Loop length is the sum of the lengths of the positive and negative leads.
3
Wire Size / Loop Length Combination Calculated using 30°C Ambient Operating Temperature.
4
Wire Size / Loop Length Combination Calculated using 40°C Ambient Operating Temperature.
5
Two-hole lug, 1/4" bolt clearance hole, 5/8" centers. Refer to drawing 031110100 for lug crimping
information.
6
Special application crimp lug / strap combination.
7
MUST USE P/N 514717 Lug Adapter Busbar for lugs having 1/4" bolt clearance hole, 5/8" centers.
8
Two-hole lug, 3/8" bolt clearance hole, 1" centers. Refer to drawing 031110100 for lug crimping
information.
9
MUST USE P/N 522786 or 534449 Lug Adapter Busbar for 125A-200A circuit breakers or P/N 514714
Lug Adapter Busbar Kit for 250A circuit breakers.
