NOTES:

1. In compliance with NEC (National Electrical Code) requirements

for multimotor and combination load equipment (refer to NEC

Articles 430 and 440), the overcurrent protective device for the

unit shall be Power Supply fuse. The CGA (Canadian Gas

Association) units may be fuse or circuit breaker.

2. Minimum wire size is based on 60 C copper wire. If other than

60 C wire is used, or if length exceeds wire length in table,

determine size from NEC.

3. Unbalanced 3-Phase Supply Voltage

Never operate a motor where a phase imbalance in supply volt-

age is greater than 2%.

Use the following formula to determine

the percentage of voltage imbalance.

% 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 =

1371

= 457

Determine maximum deviation from average voltage.

(AB) 457

(BC) 464

(AC) 457

Maximum deviation is 7 v.

Determine percent of voltage imbalance.

% Voltage Imbalance = 100 x

457

= 1.53%

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.

*Heater capacity (KW) based on heater voltage of 208v, 240v, & 480v.

If power distribution voltage to unit varies from rated heater voltage,

heater KW will vary accordingly.
