NOTES:
1. In compliance with NEC requirements for muttimotor and combination toad 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 percentage of voltage imbalance.
% Voltage Imbalance = 100 x
max voltage deviation from average voltage
average voltage
Example: Supply voltage is 230-3-60
AB = 224 v
BC = 231 v
AC = 226 v
Average Voltage = 224 + 231 + 226
3

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.

% Voltage Imbalance = 100 x
227
= 1.76%
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.
