*Units with one MCA, MOCP, and fuse size value have one terminal block and
require one power supply. Units with two MCA, MOCP, and fuse values have
2 terminal blocks.
†Wye-delta start is standard. Not available in across-the-line start.
NOTES:
1. Main power 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). An accessory con-
trol 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 unit nameplate.
7. 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.
Units have the following power wiring terminal blocks and parallel
conductors:
