Table 2 — Electrical Data

LEGEND

*Heater capacity (kW) is based on heater voltage of 208 v, 240 v, and

480 v. If power distribution voltage to unit varies from rated heater volt-
age, 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 combina-

tion load equipment (refer to NEC Articles 430 and 440), the over-
current 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).
