Circuit Breaker and Fused Disconnect Switch Sizes — 36 to 57 kW
The shaded area contains electrical information for International models only.
Wire size is based on THHN wire for branch circuit protection at .91 derate factor. Circuit breakers and fused disconnects are to
be mounted remote and wired by contractor. Sizes are based on the 2002 NECtable 310-16. Conduit size based on conductors
plus ground wire sizing per Table C1 from Appendix C.
NOTE: 250 kcmil maximum wire size for terminal block.
ELECTRIC SHOCK HAZARD: Consult a licensed electrical
contractor for proper electrical installation conforming to
local electrical codes and the National Electrical Code
(N.E.C.).
