12 Electrical and Control Wiring
IMPORTANT: All routing of electrical wiring must be made through
provided electrical knockouts. Do not cut, puncture or alter the
cabinet for electrical wiring.
12.1 Building Electrical Service Inspection
This unit is designed for single-phase electrical supply only.
DO NOT OPERATE ON A THREE-PHASE POWER SUPPLY.
Measure the power supply to the unit. The supply voltage must
be measured and be in agreement with the unit nameplate
power requirements and within the range shown.

12.2 Wire Sizing
Wire size is important to the operation of your equipment. Use
the following check list when selecting the appropriate wire size
for your unit.
FIRE HAZARD!
To avoid the risk of property damage, personal injury or fire,
use only copper conductors.
CAUTION
HIGH VOLTAGE!
Failure to do so may cause property damage,
personal injury or death.
Disconnect ALL power before servicing.
Multiple power sources may be present.
HIGH VOLTAGE!
To avoid property damage, personal injury or death due to
electrical shock, this unit MUST have an
electrical ground. The electrical ground circuit may
consist of an appropriately sized electrical wire connecting the
ground lug in the unit control box to the building electrical
service panel.
Other methods of grounding are permitted if performed in
accordance with the National Electric Code (NEC)/American
National Standards Institute (ANSI)/National Fire Protection
Association (NFPA) 70 and local/state codes. In Canada,
electrical grounding is to be in accordance with the Canadian
Electric Code (CSA) C22.1.

unbroken
• Wire used must carry the Minimum Circuit Ampacity (MCA)
listed on the unit’s Series and Rating Plate.
• Refer to the NEC (USA) or CSA (Canada) for wire sizing.
The unit MCA for the air handler and the optional electric
heat kit can be found on the unit Series and Rating Plate.
• Wire must be sized to allow no more than a 2% voltage drop
from the building breaker/fuse panel to the unit.
• Wires with different insulation temperature rating have
varying ampacities - be sure to check the temperature rating
used.
Refer to the latest edition of the National Electric Code or in
Canada the Canadian Electric Code when determining the
correct wire size.
12.3 Maximum Overcurrent Protection (MOP)
Every installation must include an NEC (USA) or CEC (Canada)
approved overcurrent protection device. Also, check with local
or state codes for any special regional requirements.
Protection can be in the form of fusing or HACR style circuit
breakers. The Series and Rating Plate provides the maximum
overcurrent device permissible.
NOTE : Fuses or circuit breakers are to be sized larger than the
equipment MCA but not to exceed the MOP.
