Best way to wire this Bathroom? GFCI, Drawing inside
 
1 Attachment(s)
Here is a drawing of what we want our bathroom setup to be. There will be 1 swtich and 1 GFCI and 2 lights (1 above the shower and 1 main light in the room)

Is it safe to wire them all on the same circuit? Where should I wire first? The GFCI first then to the light switch and then lights or light switch then lights then GFCI? Thanks.

Are both of the lights on the same switch? No fan?

Yes both lights are on the same switch. I didn't plan on putting a fan in there.

How's the current electrical set up in relation to this? For example, if you followed the wiring up from the breaker panel, where would it enter this bathroom?

Good question. I don't know since I haven't closed on the property yet. We are going to rewire the bathroom but I am not sure where it comes in. It comes from the ceiling but I am not sure what wall.

This wouldn't matter much, unless the bathroom has a dedicated 20A circuit already.

You can use one 20A circuit for the receptacle and lighting in a bath IF that circuit does not leave the bathroom.

In this case with only two lights you'd be fine doing this. I'd run to the GFI first then to the light switch.
I will all but guarantee you will need to run a new 20A circuit though.
Having not even closed on the property yet this is a bit premature and hard to tell.

Thanks. Ok so 20A breaker, #12 gauge wire, GFCI first, then switch then light fixtures. I need to plan ahead. I have a lot of work to do. I will make it its very own circuit for these 3 items. Basically going to the GFCI first if it trips it will cut off the lights also. Thanks Again.

I believe you will find that active ventilation will be required by your local inspector.

I wouldn't wire them on the same circuit. Since the bath should have a dedicated circuit I would run a 12-3 and put two circuits in there. One for just the outlet and one for the lights and fan. Not putting in a fan is a mistake, code aside.

wouldn't and "couldn't "are two different things. Would the OP have a high maintenance wife?:laughing:

twilightcall 01-12-2008 04:39 PM

Thanks guys. Ok I will put in a fan. Ron would you please show me how you would wire it for the fan? Would you run a seperate switch for the fan or would you wire it to come on with the lights? So it would be best to run a 20 amp breaker with #12 wire just for the 1 GFCI receptacal by itself and then run another 20 amp breaker and #12 wire for the lights and fan? Thanks.

Work it out logically in your head. You have answered your own question.:wink: :huh: :jester:

twilightcall 01-12-2008 07:39 PM

Just seems unnecessary to run a seperate circuit for the 1 receptacal and then a new circuit for 2 lights. Ideally I would like to run to the GFCI first and protect the lights via the GFCI. I will have to check into code on this. I would guess as long as the lights are protected that it should be ok but .....

Andy, Speedy, does the light over the shower need GFCI protection? I don't have a newer NEC. Usually they don't want lights on GFI because if it trips, everyone is in the dark. But with loads above a shower, I thought it was different. Or am I thinking of the fan?

it pretty much depending on the manufacter instrustions but in shower luminaire useally use the " shower lens " but some location required GFCI on everything in bathroom.

but for the fan it kinda half and half depending on manufacter again but IMO for myself i rather run GFCI'ed fan over non GFCI'ed fan

Merci, Marc
