*Min Ckt Amps and MOCP Amps values per NEC rounds to full wire size (see

Note 1).

NOTES:

1. In compliance with NEC requirements for multimotor and combination

load equipment (NEC Articles 430 and 440), the overcurrent protective
device for the unit shall be either circuit breaker (where available) or fuse.
Canadian units may be fuse or circuit breaker.

2. Wire sizing amps (MCA) are a sum of 125% of the condenser-fan motor

FLA.

3. Motors are protected against primary single phasing condition.
4. Three-phase voltage imbalance must not exceed 2%
