*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.
†Heaters are field installed only.
**Fuse or HACR circuit breaker.
††Electrical disconnect cannot be used if electric heater is installed.
NOTES:
1. In compliance with NEC requirements for multimotor and combination
load equipment (refer to NEC Articles 430 and 440), the overcurrent pro-
tective 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 percentage
of voltage imbalance.

Example: Supply voltage is 460-3-60.
AB = 452 v
BC = 464 v
AC = 455 v
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 percent of voltage imbalance.
% Voltage Imbalance = 100 x
This amount of phase imbalance is satisfactory as it is below the maxi-
mum allowable 2%.
IMPORTANT:
If the supply voltage phase imbalance is more than
2%, contact your local electric utility company immediately.
