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.
Only 6, 7 and 9 kW models can be field converted to single or three phase (open delta on 3 phase). Check wiring diagram supplied
with the unit when converting the phase of the unit. Larger branch circuit required than for balanced 3 phase of equal kW. Balanced
3 phase available, consult factory.
Circuit Breaker and Fused Disconnect Switch Sizes — 13.5 to 30 kW
