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. Canadian 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 percentage of voltage imbalance.

% Voltage Imbalance

= 100 x

max voltage deviation from average voltage

average voltage

Example: Supply voltage is 230-3-60

AB = 224 v
BC = 231 v
AC = 226 v

Average Voltage =

(224 + 231 + 226)

681

227

Determine maximum deviation from average voltage.
(AB) 227 – 224 = 3 v

Maximum deviation is 4 v.

. . . . . . . . . .

(BC) 231 – 227 = 4 v

Determine percent of voltage imbalance.

. . . . . . . . . .

% Voltage Imbalance

= 100 x

227

= 1.76%

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.
