ELECTRICAL NOTES
1. As standard, all units have single point power connection. Contact factory for information regarding dual point power units.
2. Maximum Inverse Time Circuit Breaker - 250% of the rated input current of the drive per NEC 430.52 (C1).
3. Maximum Dual Element (Time Delay) Fuse - 225% of the rated input current of the drive per NEC 430.52 (C1).
4. 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
5. 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.
6. RLA - Rated Load Amps - rated in accordance with UL standard 1995.
7. Local codes may take precedence.
8. Control KVA includes operational controls and evaporator heaters.
9. System inrush current is less than RLA due to the use of YORK Variable Speed Drive technology. Typical Compressor Starting Current
( .rst four seconds of startup):
