'Heaters are field installed only.
tUsed to determine minimum disconnect size per NEC
"Heater capacity (kW) is based on heater voltage of 240 v, 480 v or 575 v If power
distribution voltage to unit varies from rated heater voltage, heater kW will vary
accordingly
ttFuse or HACR circuit breaker
((Fusing in single point box provides the required branch circuit protection
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 The CSA 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 % voltage imbalance
% Voltage imbalance
max voltage deviation from average voltage
= 100
X
-;;-
average voltage
Full Load Anurs
Heating, Air Conditioning and Refrigeration
Indoor (Evaporator) Fan Motor
Locked Rotor Amps

Maximum Overcurrent Protection
Outdoor (Condenser) Fan Motor
Rated Load Amps
Example; Supply voltage Is 460-3-60
AB = 452
V
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 % voltage imbalance
7
% Voltage imbalance = 100 x-
= 1 53%
457
This amount of phase imbalance is satisfactory as it is below the maximum al¬
lowable 2%
IMPORTANT; If the supply voltage phase imbalance is more than 2%, contact
your local electric utility company immediately
