NO TES:
1. In compliance with NEC (National Electrical Code) requirements
for multimotor and combination load equipment (refer to NE C
Articles 430 and 440), the overcurrent protective device for the
unit shall be Power Supply fuse. The CGA (Canadian Gas
Association) units may be fuse or circuit break er.
2. Minimum wire size is based on 60 C copper wire. I f other than
60 C wire is used, or if length exceeds wire length in table,
determine siz e from NEC..
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 230-3-60.
AB = 228 v
BC = 231 v
AC = 227 v
228 + 231 + 227
Average Voltage =
3
686
=
3
= 229
Determine maximum deviation from average voltage.
(AB) 229 -
(BC) 231 -
(AC) 229 -
Maximum deviation is 2 v.
Determine percent of voltage imbalance.
2
% Voltage Imbalance = 100 x
229
= 0.8%
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.
