LEGEND
FLA
— Full Load Amps
ICF
— Maximum Instantaneous Current Flow During Starting.
(The point in the starting sequence where the sum of
the LRA for the starting compressors, plus the total RLA
for all running compressors, plus the FLA for all running
fan motors is maximum.)
kcmil
— Thousand Circular Mils
LRA
— Locked Rotor Amps
MCA
— Minimum Circuit Amps (used for sizing; complies with
National Electrical Code [NEC] [U.S.A. Standard],
section 430-24).
MOCP — Maximum Overcurrent Protection (used for sizing
disconnect; complies with NEC [U.S.A. Standard],
section 440- 22).
PW
— Part Wind
RLA
— Rated Load Amps
*Units are suitable for use on electrical systems where voltage sup-
plied to unit terminals is within listed minimum to maximum limits.
†All compressors are across-the-line start only except 346-v, 3-ph,
50 Hz unit.
NOTES:
1. Maximum allowable phase imbalance: voltage - 2%; amps - 10%.
2. Maximum incoming wire size for terminal block is 500 kcmil.
