LEGEND
*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).
