Why would it have to be wired to the light switch ? There should be no reason that the fan cant be wired directly to the power source before the light switch, not after?
I want to place one with both an in and an outflow in my forward vent in our Rockwood 2304KS. There is a light close by.
Also need one of those Maxxair covers to eliminate the rain issues. I LOVE the one that came with the bathroom in our tt
If the light is operated by a wall switch, the power (black wire) should come first to the switch, then to the fixture. The neutral (white wire) would bypass the switch and go directly to the fixture. If your unit has a cigarette lighter type outlet near the switch, this is the logical way to wire. I am thinking that this is the wiring method in campers. In this instance, the light switch has to remain on for the fan to work. If your ceiling fixture has an on/off switch, the light would be operated from fixture switch and the fan would also have to be operated at the fan (unless you wanted neither on).
An optional wiring method is to wire the hot lead at the fixture, then bring the hot lead through switch and back to the black wire on the fixture. The latter is used to eliminate long runs of neutral wire. I don't think your that lucky. But, if you are, you won't need to go through the switch.
This is a fan we are considering.
