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 running
compressors is at a maximum)
LRA — Locked Rotor Amps
MCA — Minimum Circuit Ampacity (for wire sizing)
MOCP — Maximum Overcurrent Protection
RLA — Rated Load Amps
WD — Wye-Delta Start
XL — Across-the-Line Start
NOTES:
1. Each main power source must be supplied from a field-supplied fused
electrical service with a (factory-installed 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). An
accessory control transformer may be used to provide control circuit
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 name-
plate.
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 nameplate.
