Notes:
1. MCA: Minimum Circuit Ampacity is 125% of the largest compressor RLA or Drive input current, plus 100% of the other compressor (s) RLA,
plus the sum of the condenser fan RLA, plus any other load rated at 1 AMP or more.
2. Maximum Breaker Overcurrent Protection (MOP): 225% of the largest compressor RLA or VSD drive Input, plus 100% of the other
compressor(s) RLA, plus the sum of the condenser fan Motor/Drive FLA, plus any other load rated at 1 AMP or more.
3. Recommended Disconnect switch: 110% to 115% of the sum of the RLA of the compressors, VSD drive input, fan motor/drive and controls FLA.
4. RLA: Rated in accordance with UL standard 1995
5. Local codes may take precedence.
6. Fix speed compressor are across the line starting, the VSD compressors are controlled by VSD drive. Compressors will never start
simultaneously.
7. Voltage utilization range is ±10 percent.
