ROUTING 24 VDC WIRING:

Following Airxcel’s low voltage wiring specications and local National Electrical Codes (NEC), route

the Roof Top Unit 24VDC supply wiring from its power source to the wire box. Use the chart below as a

guide knowing the amp draw listed on the unit rating plate to size the minimum wire size for use for the

distance in feet between the unit and your power supply.

This is a ve percent table which means at these amperage ratings at the listed distances, 5% of the power

would be lost to resistance.

ELECTRIC CIRCUIT

DC POWER REQUIREMENT: 1243 Watts

OPERATING CURRENT: 13 - 40 Amps

MINIMUM CIRCUIT AMPACITY (DC AMPS): 50

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 DISCONNECTED BEFORE

PERFORMING ANY WORK ON THE UNIT TO AVOID THE POSSIBILITY OF SHOCK

INJURY OR DAMAGE TO THE EQUIPMENT.
