Notes:

1.Minimum circuit ampacity is 125% of the largest compressor RLA, plus 100% of the remaining compressor(s) RLA, per NEC 440-32 and NEC 440-33.

2.Maximum fuse size is 225% of the largest compressor RLA, plus 100% of the remaining compressor(s) RLA, per NEC 440-33.

3.Recommended dual element fuse size is 175% of the largest compressor RLA, plus 100% of remaining compressor(s) RLA, per NEC 440-33.

4.Use copper conductors only.
