V. ELECTRICAL WIRING
ROUTING 115 VAC Wiring
Following Airxcel's high voltage wiring specifications and
all local and national electrical codes, route the 115 VAC
supply wiring from its power source to the wire box.
High Voltage Wiring Specifications based on Minimum
Overcurrent Protective Device Amperage – (see upper
unit nameplate)
1. U.L. requires copper conductors only with minimum
#12 AWG when using the minimum recommended
overcurrent protection device. Higher rated devices
or longer wiring runs will require #10 AWG or greater
copper conductors.
2. To prevent voltage drops greater than 10% during
starting loads, adhere to the following guideline:
For lengths greater than 50', use #10 AWG or larger
copper conductors. Match to the overcurrent
protection device provided.
Circuit Protection – Refer to upper unit nameplate.
Electrical Wiring High Voltage Wiring Specification
is based on Overcurrent Protection Device rated
higher than the minimum required (see upper unit
nameplate).
Follow all local and NEC (National Electrical Code) for
proper sizing of wire AWG based on Overcurrent
Protection Device selected and the length of the wiring
run to the air conditioner.
DANGER – SHOCK HAZARD
MAKE SURE THAT ALL POWER SUPPLY TO
THE UNIT IS
PERFORMING ANY WORK ON THE UNIT TO
AVOID THE POSSIBILITY OF SHOCK INJURY
OR DAMAGE TO THE EQUIPMENT.
DANGER! – WHEN USING NON-METALLIC
SHEATH CABLES
SHEATH BACK TO EXPOSE 4-6 INCHES OF THE
SUPPLY LEADS.
STRIP THE INDIVIDUAL WIRE LEAD ENDS FOR
WIRE CONNECTION (ABOUT 3/4" BARE WIRE).
INSERT THE SUPPLY WIRES INTO THE
ELECTRICAL CONNECTOR CLAMP. SHEATH
MUST PROTRUDE PAST THE CLAMP BUSHING
INSIDE THE BOX. MAKE SURE SHEATH CABLE
IS CENTERED IN CLAMP BEFORE TIGHTENING
CLAMP ON SHEATH CABLE!!
DO NOT OVERTIGHTEN!! THIS COULD RESULT
IN PINCHING THROUGH THE PLASTIC WIRE
INSULATION AND CAUSE SHORTING OR "HOT"
WIRES TO GROUND (SHOCK HAZARD). THE
CLAMP IS INTENDED FOR STRAIN RELIEF OF
THE WIRES. SLIGHT PRESSURE IS USUALLY
SUFFICIENT TO ACCOMPLISH THIS.
IF OTHER THAN NON-METALLIC CABLES ARE
USED FOR
APPROPRIATE STRAIN RELIEF CONNECTORS
OR CLAMPS SHOULD BE USED.
IN NO CASE SHOULD CLAMPING OR PINCHING
ACTION BE APPLIED TO THE INDIVIDUAL
SUPPLY LEADS (NEUTRAL AND "HOT" WIRES).
