*Heater capacity (kW) is based on heater voltage of 208v, 240v, 480v, or 600v. If power

distribution voltage to unit varies from rated heater voltage, heater kW will vary accord-

ingly.

Fuse or HACR circuit breaker.

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. Canadian 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 percentage of voltage imbalance.

% Voltage Imbalance

= 100 x

max voltage deviation from average voltage

average voltage

Example: Supply voltage is 230---3---60

AB = 224 v

BC = 231 v

AC = 226 v
Average Voltage = 224 + 231 + 226

3

=

Determine maximum deviation from average voltage.

(AB) 227 – 224 = 3 v
(BC) 231 – 227 = 4 v

(AC) 227 – 226 = 1 v
Maximum deviation is 4 v.

Determine percent of voltage imbalance.

% Voltage Imbalance

227

= 1.76%

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

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