*Used to determine minimum disconnect per NEC.
†Single point box CRSINGLE017A00 is part of base unit.
NOTES:
1. In compliance with NEC requirements for multimotor and combination load equipment
(refer to NEC Articles 430 and 440), the overcurrent protective device for the unit shall
be fuse or HACR breaker. UL, Canada units may be fuse or circuit breaker.
2.
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 determine the percent of voltage imbalance.
Example: Supply voltage is 460-3-60.
AB = 452 v
BC = 464 v
AC = 455 v
= 457
Determine maximum deviation from average voltage.
(AB) 457 – 452 = 5 v
(BC) 464 – 457 = 7 v
(AC) 457 – 455 = 2 v
Maximum deviation is 7 v.
Determine percent of voltage imbalance.
% Voltage Imbalance = 100 x
= 1.53%
This amount of phase imbalance is satisfactory as it is below the maximum allowable 2%.
