*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 cir- cuit 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.

max voltage deviation from average voltage

= 100 x

average voltage

Example: Supply voltage is 460-3-60.

AB = 452 v

BC = 464 v

AC = 455 v

452 + 464 + 455

Average Voltage =

3

1371

=

3

=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	7
	457
= 1.53%

This amount of phase imbalance is satisfactory as it is below the maximum allow- able 2%.

IMPORTANT: If the supply voltage phase imbalance is more than 2%, contact your local electric utility company immediately.
