FLA	— Full Load Amps
MOCP	— Maximum Overcurrent Protection

*Motors are designed for satisfactory operation within 10% of nominal volt- ages shown. Voltages should not exceed the limits shown in the Voltage Lim- its column.

Determine maximum deviation from average voltage.

(AB) 397 – 393 = 4 v (BC) 403 – 397 = 6 v (AC) 397 – 396 = 1 v

Maximum deviation is 6 v.

Determine percent voltage imbalance.

NOTES:

1. Minimum circuit amps (MCA) and MOCP values are calculated in accor-

% Voltage Imbalance = 100 x

	dance with NEC (National Electrical Code), Article 440.
2.	Motor FLA values are established in accordance with UL (Underwriters’
	Laboratories) Standard 1995.
3.	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.

max voltage deviation from average voltage

= 100 x

average voltage

EXAMPLE: Supply voltage is 400-3-50.

AB = 393 v

BC = 403 v

AC = 396 v

393 + 403 + 396

Average Voltage =

3

1192

=

3 = 397

397

= 1.5%

This amount of phase imbalance is satisfactory because 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.
