I have a bathroom fan/light/night light combo unit that allows for all 3 features to be switched separately (a connector for each). I want a timer for the fan, and separate switches for each light. I'm wondering the best way to wire that.
I could just add a 12/3 cable with two hot wires and a 12/2 cable to control all three features. Or 3 12/2 cables. But I was wondering, if one were starting from scratch would they run 3 separate cables from the switch to the fan combo? Or something else?
So my thought was, could I run conduit and put a ground, neutral, and 3 hots through it, between the switches and the fixture. I realize that would mean all 3 things going through the same neutral, but that would be the case anyway if I just ran 3 cables from the switches.
So is that a valid use of conduit? I also looked for existing cables with 1 neutral and 3 hots (grounded). I think they exist but I can't tell if they're for home wiring or to any sort of electrical code or anything.
I'm having a hard time finding the answer because I don't know how to ask. Being an amateur, I want to go with something I know is correct so I'm wary with this.
