LRA	—	Locked Rotor Amps
MCA	—	Minimum Circuit Amps
MOCP —		Maximum Overcurrent Protection
NEC	—	National Electrical Code
RLA	—	Rated Load Amps

*Heater capacity (kW) is based on heater voltage of 208 v, 240 v, 480 v and 600 v. If power distribution voltage to unit varies from rated heater voltage, heater kW will vary accordingly.

†Fuse or HACR circuit breaker. This is the maximum size permissible; smaller fuse size may be used where conditions permit.

NOTES:

1.In compliance with NEC requirements for multimotor and combination load equipment (refer to NEC Articles 430 and 440), the overcurrent protective device for the unit shall be fuse or HACR breaker. The Canadian units may be fuse or circuit breaker.

2.MCA calculation for units with electric heaters over 50 kW = (1.25 x IFM amps) + (1.00 x heater FLA).
