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.

2.Unbalanced 3-Phase Supply Voltage

Never operate a motor where, a phase imbalance in supply voltage is o

greater than 2_, Use the following formula to determine the percent of volt- age imbalance,

% Voltage Imbalance

= 457

Determine maximum deviation from average voltage. (AB) 487 - 482 = 8 v

(BC) 464 - 487 = 7 v

(AC) 487 - 488 = 2 v

Maximum deviation is 7 v.

Determine percent of voltage imbalance. 7

% Voltage Imbalance = 100 x 487

= 1.53%

This amount of phase imbalance is satisfactory as it is below the maximum allowable 2%.
