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 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 a unit. 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.

WARNING! Consult a licensed electrical contractor for proper electrical installation conforming to local electrical codes and the National Electrical Code (N.E.C.).
