*Available for ®eld-installed accessory heaters only. Heater capacity (kW) is based on heater voltage of 208 v, 240 v or 480 v. If power distribution voltage to unit varies from rated heater voltage, heater kW will vary accordingly.

²Fuse or HACR circuit breaker.

**Used to determine minimum disconnect per NEC.

²²Fusing single-point box provides the required branch circuit protection. Ampacities are based on 460 v. MCA and MOCP are based on 575 v.

NOTES:

1.In compliance with NEC requirements for multimotor and combination load equip- ment (refer to NEC Articles 430 and 440), the overcurrent protective device for the unit shall be fuse or HACR 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.

= 1371

3

= 457

NOTE: The 575-v units are Canada only.

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 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.
