Example: Supply voltage is 460-3-60.

CSA	Ð Canadian Standards Association
FLA	Ð Full Load Amps
HACR	Ð Heating, Air Conditioning and Refrigeration
LRA	Ð Locked Rotor Amps
MCA	Ð Minimum Circuit Amps
MOCP Ð Maximum Overcurrent Protection

AB = 452 v

BC = 464 v

AC = 455 v

Average Voltage =

452 + 464 + 455

NEC	Ð National Electrical Code (U.S.A. Standard)
OFM	Ð Outdoor (Condenser) Fan Motor
RLA	Ð Rated Load Amps

= 457

(AB) 457 - 452 = 5 v (BC) 464 - 457 = 7 v

(AC) 457 - 455 = 2 v Maximum deviation is 7 v. Determine percent voltage imbalance

% Voltage Imbalance = 100 x

NOTES:

1.In compliance with NEC requirements for multimotor and combina- tion load equipment (refer to NEC Articles 430 and 440), the over- current protective device for the unit shall be fuse or HACR breaker.

2.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 voltage imbalance.

457

= 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.

3.The 575-v units are CSA only.

4.The 380-v units are not UL or CSA listed.
