NOTES
1
In compliance with NEC requirements for multimotor
and
combination load equipment (ref NEC Articles 430 and 440),
the overcurrent protective device for the unit shall be fuse only

Use the following formula to determine
the % voltage unbalance
% Voltage Unbalance

'Fuse only
Determine maximum deviation from average voltage
(AB) 457 - 452 = 5 volts
(BC) 464 - 457 = 7 volts
(AC) 457 - 455 = 2 volts
Maximum deviation is 7 volts
Determine % voltage unbalance
% Voltage Unbalance = 100 x = 1 53%

This amount of phase unbalance is satisfactory as it is below
the maximum allowable 2%
