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.
5. Voltage Utilization Range: Rated Voltage
