FLA — Full Load Amps
LRA — Locked Rotor Amps
MCA — Minimum Circuit Amps (for wire sizing) Complies with
NEC, Section 430-24
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
2 Unbalanced 3-Phase Supply Voltage
Never operate a motor where a phase unbalance in supply volt¬
age is greater than 2% Use the following formula to determine
the % voltage unbalance
% Voltage Unbalance
_ qq ^ max voltage deviation from average voltage
average voltage
Example Supply voltage is 460-3-60
MOCP — Maximum Overcurrent Protection
RLA — Rated Load Amps
*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—r— = 1 53%
457
This amount of phase unbalance is satisfactory as it is below
the maximum allowable 2%
