FLA
— Full Load Amps (fan motors)
ICF
— Maximum Instantaneous Current Flow during start-up
(LRA of compressor plus total FLA of fan motors)
LRA
— Locked Rotor Amps
MCA
— Minimum Circuit Amps per NEC Section 430-24
MOCP — Maximum Overcurrent Protection (fuse only)
RLA
— Rated Load Amps (compressor)
*Units are suitable for use on electrical systems where voltage supplied
to the unit terminals is not below or above the listed limits.
NOTES:
1. MCA and MOCP values are calculated in accordance with NEC
(National Electric Code), Article 440.
2. Motor RLA and FLA values are established in accordance with
UL (Underwriters’ Laboratories) Standard 1995.
