Adding a Ceiling Fan

[tpaolillo]

Hi, Im wanting to add a 110v ceiling fan just in front of the AC unit but on the other side of the roof rafter. (See attached pic). My question is, is there any documentation that may show if there is 110v in the ceiling at that location that i can tap into. I was thinking of tapping into the AC wiring but also dont know the path of the wiring. Any suggestions so i dont just cut a hole in the ceiling with no wires?
Thanks

Hi tpaolillo

In the past, I've used a Non-contact voltage tester to locate the 120 volt wires. Simply plug into shore power and swipe the tester along the ceiling to locate the wires.

The ceiling lights can be removed, allowing a hand to get stuck up in the hole to feel around for wires or use an inspection camera. (This assumes there's a light close to where you want the fan to be located.)

Based on where the AC unit is, you could probably fish a wire from the fan to the AC to get power. IIRC the roof is trussed not solid which should allow for passing the wire easily.

The harder thing is going to be getting sufficient support for the fan if there is not a longitudinal member between the transverse trusses.

Before you get too far down this road, tpaolillo , please check amperage needed vs. amperage available. It is likely that the only AC power source in the ceiling will be for the air conditioner. Add up the amperage required for the air conditioner and the ceiling fan and make sure the sum is less than the rating of the breaker for air conditioner circuit.
