NOTES:

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

nation load equipment (refer to NEC Articles 430 and 440), the

overcurrent protective device for the unit shall be fuse or HACR

breaker.

Unbalanced 3-Phase Supply Voltage

Never operate a motor where a phase imbalance in supply volt-

age 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%.

3. The 575-v units are CSA only.

4. the 380 v, 60 Hz units and all 50 Hz units are

not

UL or CSA

listed.
