581B090-120 HIGH-STATIC MOTOR (Units Without Electrical Convenience Outlet)

581B090-120 HIGH-STATIC MOTOR (Units With Electrical Convenience Outlet)

LEGEND

*Used to determine minimum disconnect per NEC.

†Fuse or HACR circuit breaker per NEC.

NOTES:

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

tion load equipment (refer to NEC Articles 430 and 440), the overcur-
rent protective device for the unit shall be fuse or HACR breaker. The
UL, Canada approved 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.

% 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 maxi-
mum allowable 2%.

IMPORTANT:

If the supply voltage phase imbalance is more than 2%,

contact your local electric utility company immediately.
