Electrical Notes
NOTES:
1. U.L. Label is provided on 50 and 60 Hz units for these electrical wiring configurations.
2. –– –– –– –– –– –– Dashed Line = Field Provided Wiring.
3. The above recommendations are based on the National Electric Code and using copper conductors only. Field wiring must also comply
with local codes. Group Rated breaker must be HACR type for cUL machines.
1. As standard, all 2 and 3 compressor units have single point power connections. The YCIV0457PA/
YCIV1649PA has dual point power connection as standard. Contact factory for information regarding
dual point power 2 and 3 compressor units.
2. Maximum Inverse Time Circuit Breaker or Dual Element Fuse - 225% of the largest compressor RLA
plus the sum of all other loads per NEC 440.22 (A).
3. MCA - Minimum Circuit Ampacity - 125% of the largest compressor RLA plus 100% of the remaining
compressor RLA's plus the sum of all condenser fan FLA's per NEC 440.33
4. Recommended time delay or dual element fuse size - 150%of the largest compressor RLA plus 100%
of the remaining compressor RLA's plus the sum of all condenser fan FLA's.
5. RLA - Rated Load Amps - rated in accordance with UL standard 1995.
6. Local codes may take precedence.
7. Control KVA includes operational controls and evaporator heaters.
8. System inrush current is less than RLA due to the use of York Variable Speed Drive technology. Typical
Compressor Starting Current ( first four seconds of startup):
