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 Utilization Range
208-230/60 188-253
380/60 342-418
460/60 414-506
575/60 517-633
400/50 360-440
6. Local codes may take precedence.
7. If unit is ordered with the High Condenser Entering Water Temperature Range (90-130), use CCAF electrical information.
