Units are suitable for use on electrical systems where voltage
supplied to the unit terminals is not below or above the listed
limits.
NOTES:
1. The MCA and Fuse values are calculated in accordance with
The NEC. Article 440.
2. Motor RLA and LRA values are established in accordance
with Underwriters’ Laboratories (UL). Standard 1995.
3. The 575---v units are UL, Canada---listed only.
4.
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 de-
termine the percentage of voltage imbalance.
Example: Supply voltage is 230-3-60
% Voltage Imbalance
= 100 x
max voltage deviation from average voltage
average voltage
AB = 224 v
BC = 231 v
AC = 226 v
Average Voltage =
(224 + 231 + 226)
=
681

=
227
Determine maximum deviation from average voltage.
(AB) 227 – 224 = 3 v
(BC) 231 – 227 = 4 v
(AC) 227 – 226 = 1 v
Maximum deviation is 4 v.
Determine percent of voltage imbalance.
% Voltage Imbalance
= 100 x

227
= 1.76%
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.
