581B036-072 STANDARD MOTOR (Units Without Electrical Convenience Outlet)

581B036-072 STANDARD MOTOR (Units With Electrical Convenience Outlet)

LEGEND

*Used to determine minimum disconnect per NEC.

†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. UL, Can-
ada units may be fuse or circuit breaker.

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.

Example: Supply voltage is 460-3-60.

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

= 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.

% Voltage Imbalance = 100 x

= 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%, con-

tact your local electric utility company immediately.
