ICF	—	Maximum Instantaneous Current Flow

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. An optional control transformer may be used to provide control circuit power from the main unit power supply.

3.Maximum instantaneous current flow (ICF) during start-up is 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.

4.Maximum incoming wire size for each terminal block is 500 kcmil.

5.Maximum allowable phase imbalance is: voltage, 2%; amps, 5%.

6.Use copper conductors only.

7.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 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 nameplate.
