NOTES:
1. In compliance with NEC requirements for multimotor and combina-
tion load equipment (NEC Articles 430 and 440), the overcurrent
protective device for the unit shall be fuse or HACR circuit breaker.
Canadian units may be fuse or circuit breaker.
2. Wire sizing amps are a sum of 125% of the compressor RLA plus
100% of indoor fan motor FLA.
3. Motors are protected against prim
ary single phasing condition.
4. Indoor-fan motors are 3-phase motors of same voltage as unit.
