FLA = Full Load Amps, N.E.C.

Table 430 - 150

Voltage utilization range is ±10 percent

Determination of minimum circuit ampacity (MCA).

MCA = 1.25 x largest motor amps/VFD amps (FLA or RLA) + the sum of the remaining motor amps.

Determination of maximum fuse size (MFS) and maximum circuit breaker size (MCB)

MFS and MCB = 2.25 x largest motor amps (FLA or RLA) + the sum of the remaining motor amps.

Units with the dual power option require separate MFS and MCB calculations for each electrical circuit:

1) fans and 2) compressors.

If the rating value calulation does not equal a standard over current protective device rating, use the next lower standard rating as the maximum.
