*Used to determine minimum disconnect per NEC.

†Fuse or HACR circuit breaker.

NOTES:

1. In compliance with NEC requirements for multimotor and combi-

nation load equipment (refer to NEC Articles 430 and 440), the

overcurrent protective device for the unit shall be fuse or HACR

breaker. UL, Canada units may be fuse or circuit breaker.

Example: Supply voltage is 460-3-60.

AB = 452 v BC = 464 v AC = 455 v

Average Voltage = 452 + 464 + 455 3

1371

=

3

= 457

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.

2. Unbalanced 3-Phase Supply Voltage

Never operate a motor where a phase imbalance in supply volt-

% Voltage Imbalance= 100 x

7

age is greater than 2%. Use the following formula to determine

the percent of voltage imbalance.

= 100 x	max voltage deviation from average voltage
	average voltage

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.
