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 permissi-
ble; smaller fuse size may be used where conditions permit.
NOTES:
1. In compliance with NEC requirements for multimotor and com-
bination 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).
