*Heater capacity (kW) is based on heater voltage of 208 v, 240 v, 480 v or
600 v. If power distribution voltage to unit varies from rated heater voltage,
heater kW will vary accordingly.
l-Fuse or HACR circuit breaker,
NOTES:
1. In compliance with NEC requirements for multimotor and combination load
equipment (refer to NEC Articles 430 and 440), the overcurrent protective
device for the unit shall be fuse or HACR breaker. Canadian units may be
fuse or circuit 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 of
voltage imbalance,
% Voltage Imbalance
= 100 x max voltage deviation from average voltage
average voltage
Example: Supply voltage is 230-3-60.
A B c AB = 224v
BC = 231 v
AC = 226 v
Average Voltage -
224 + 231 + 226

= 227
Determine maximum deviation from average voltage.
(AB) 227 - 224 = 3 v
(BC) 231 - 227 = 4 v
(AC) 227 - 226 = 1 v
Maximum deviation is 4 v.
Determine percent of voltage imbalance.
4
% Voltage Imbalance = 100 x 22"_-
= 1.76%
This amount of phase imbalance is satisfactory as it is below the maximum
allowable 2%.
I IMPORTANT: If the supply voltage phase imbalance is more than 2%, 1
contact the local electric utility company immediately.
