SECTION 6 - TECHNICAL DATA
ELECTRICAL NOTES
1. As standard, all units have single point power con-
nection. Contact factory for information regarding
dual point power units.
2. Maximum Inverse Time Circuit Breaker or Dual
Element Fuse - 225% of the largest compressor
RLA plus the sum of all the other loads per NEC
440.22 (A).
3. MCA - Minimum Circuit Ampacity - 125% of the
largest compressor RLA plus 100% of the remain-
ing compressor RLA’s plus the sum of all con-
denser 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.
