NOTES:

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

tion load equipment (refer to NEC Articles 430 and 440), the over-

current 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

voltage imbalance.

% Voltage Imbalance

max voltage deviation from average voltage

= 100 x

average voltage

EXAMPLE: Supply voltage is 460-3-60.

AB = 452 v

BC = 464 v

AC = 455 v

452 + 464 + 455

Average Voltage =

1371

= 457

Determine maximum deviation from average voltage.

(AB) 457 - 452=5v

(BC) 464 - 457=7v

(AC) 457 - 455=2v

Maximum deviation is 7 v.

Determine percent voltage imbalance.

% Voltage Imbalance = 100 x

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.
