Wire size is based on THHN insulated, copper 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 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.
