*Fuse or HACR Breaker.
NOTES:
1. In compliance with NEC (National Electrical Code) 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. The CGA (Canadian Gas
Association) units may be fuse or circuit breaker.
2. Minimum wire size is based on 60 C copper wire. If other than
60 C wire is used, or if length exceeds wire length in table,
determine size from NEC.
3. 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.

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.

= 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.
