FLA
— Full Load Amps
ICF
— Maximum Instantaneous Current Flow during start-up (the
point in the starting sequence where the sum of the LRA
for the start-up compressor, plus the total RLA for all run-
ning compressors, plus the total FLA for all running fan
motors is at a maximum)
LRA
— Locked Rotor Amps
— Minimum Circuit Ampacity (for wire sizing)
MCA
MOCP — Maximum Overcurrent Protection
RLA
— Rated Load Amps
WD
— Wye-Delta Start
XL
— Across-the-Line Start
*All units have one MCA, MOCP and fuse size value. All units require
one power supply.
†Wye-delta start is standard, not available in across-the-line start.

NOTES:
1. Each main power source must be supplied from a field-supplied fused
electrical service with a (factory- or field-installed) disconnect located
in sight from the unit.
2. Control circuit power must be supplied from a separate source
through a field-supplied disconnect (except for 380/415-50 units). The
control circuit accessory transformer may be applied to power from
the main unit power supply.
3. Maximum incoming wire size for each terminal block is 500 kcmil.
4. Maximum allowable phase imbalance is: voltage, 2%; amps, 5%.
5. Use copper conductors only.
6. The MOCP is calculated as follows:
MOCP = (2.25) (largest RLA) + the sum of the other RLAs. Size the
fuse one size down from the result. The RLAs are listed on the unit
nameplate.
The recommended fuse size in amps (RFA) is calculated as follows:
RFA = (1.50) (largest RLA) + the sum of the other RLAs. Size the
fuse one size up from the result. The RLAs are listed on the unit
nameplate.
