CIRCUIT BREAKER & FUSED DISCONNECT SWITCH SIZES - 36 to 57 kW

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 NEC table

310-16. Conduit size based on conductors plus ground wire sizing per Table C1 from Appendix C.

Only 6, 7 & 9 kW models can be field converted to single or three phase (open delta on 3 phase). Larger

branch circuit required than for balanced 3 phase of equal kW. Balanced 3 phase available, consult factory.

NOTE: 250 kcmil maximum wire size for terminal block.
