*Heater capacity (kW) is based on heater voltage of 208 v, 240 v, or
480 v. If power distribution voltage to unit varies from rated heater volt-
age, heater kW will vary accordingly.
†Fuse or HACR circuit breaker.
NOTES:
1. In compliance with NEC requirements for multimotor and combina-
tion load and equipment (refer to NEC Articles 430 and 440), the
overcurrent protective device for the unit shall be fuse or HACR breaker.
2. Unbalanced 3-Phase Supply Voltage
Never operate a motor where a phase imbalance in supply voltage is
greater than 2%. Use the following formula to determine the percent-
age of voltage imbalance.

EXAMPLE: Supply voltage is 460-3-60
AB = 452 v
BC = 464 v
AC = 455 v
Average voltage =
Determine maximum deviation from average voltage:
(AB) 457 − 452 = 5 v
(BC) 464 − 457 = 7 v
(AC) 457 − 455 = 2 v
Maximum deviation is 7 v.
Determine percentage of voltage imbalance:
% Voltage imbalance = 100 x
This amount of phase imbalance is satisfactory as it is below the
maximum allowable 2%.
IMPORTANT:
If the supply voltage phase imbalance is more than 2%
contact your local electric utility company immediately.
