Notes:
1. Minimum circuit ampacity (MCA) is 125 percent of the RLA of one compressor motor plus the total RLA of the remaining motors.
2. Maximum Overcurrent Protection Device permitted by NEC 440-22 is 225 percent of the RLA of one compressor motor plus the total RLA of the remaining motors.
3. Recommended dual element fuse size is 150 percent of the RLA of one compressor motor plus the total RLA of the remaining motors.
4. Local codes may take precedence.
