Recommended Wire Sizes
North American wire sizes (AWG) are based on NEC/NFPA-70 for ampacities of thermoplastic-insulated (75ºC) copper conductors assuming not
more than three current-carrying conductors in raceway or cable, based on ambient temperature of 40ºC. The wire sizes allow for an ampacity of 125%
of the rated input and output amperes for motor branch-circuit conductors as specified in NEC/NFPA-70.
The table below gives the wire sizes for the input (supply) and output (motor) wiring. The table includes the rated input and output amperes for each
model at 460V or 575V operation.
