FLA — Full Load Amps
HACR — Heating, Air Conditioning and Refrigeration
IFM — Indoor (Evaporator) Fan Motor

*Heater capacity (kW) is based on heater voltage of 208 v, 240 v, 480 v, and
575v.Heaters arerated at240v,480v,and 575v. Ifpower distributionvoltageto unit
varies fromrated heatervoltage, heaterkW willvary accordingly.Todetermine heater
capacity at actual unit voltage, multiply 240 v, 480 v, or 575 v capacity by multipliers
found in Electric Heat Multiplication Factors table on page 48.
†Used to determine minimum disconnect size per NEC.
**Heaters are field installed only.
††Fuse or HACR circuit breaker.
Fusing in single point box provides the required branch circuit protection.
NOTES:
1. IncompliancewithNECrequirementsfor multimotorandcombinationloadequipment
(refertoNECArticles430and 440),theovercurrentprotectivedevice fortheunitshall
be fuse or HACR breaker. The 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 percent of voltage imbalance.
max voltage deviation from average voltage
% Voltage Imbalance =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 −452 = 5 v
(BC) 464 −457=7v
(AC) 457 −455=2v
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.
3. MCA calculation for 558F180-300 units with electric heaters over 50 kW =
