*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 voltage, heater
kW will vary accordingly.
†Fuse or HACR circuit breaker.
NOTES:
1. In compliance with NEC requirements for multimotor and combination load and
equipment (refer to NEC Articles 430 and 440), the overcurrent protective de-
vice 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 percentage of voltage
imbalance.
% Voltage Imbalance
max voltage deviation from average voltage
= 100 x
average voltage
EXAMPLE: Supply voltage is 460-3-60
AB = 452 v
BC = 464 v
AC = 455 v
452 + 464 + 455
Average voltage =
3
= 457
Determine maximum deviation from average voltage:
(AB) 457 − 452=5v
(BC) 464 − 457=7v
(AC) 457 − 455=2v
Maximum deviation is 7 v.
Determine percentage of voltage imbalance:
7
% Voltage imbalance = 100 x
457
= 1.53%
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.
