FLA
— Full Load Amps
MOCP — Maximum Overcurrent Protection
*Motors are designed for satisfactory operation within 10% of nomi-
nal voltages shown. Voltages should not exceed the limits shown in
the Voltage Limits column.
NOTES:
1. Minimum Circuit Amp and MOCP values are calculated in
accordance with NEC (National Electrical Code) (U.S.A. stand-
ard), Article 440.
2. Motor FLA values are established in accordance with UL (Under-
writers’ Laboratories) Standard 1995 (U.S.A. standard).
3. 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 percentage of voltage imbalance.
% 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 =

1192
=

= 397
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.

% Voltage Imbalance = 100 x
397
= 1.5%
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%, contact your local electric utility company immediately.
