Question:

Electrical Wiring in Bathroom with feed into light?

I have strange wiring in my bathroom that I am trying to figure out and get working again. I have a two conductor with ground going into my fixture carrying the feed, then a three conductor with ground going to the switch. From the switch, there is a black wire jumped to the switch beside it(for the fan), then to the receptacle beside that. The white from the 3 conductor is going into the receptacle, the red and black into the switch for the light. Then there is a two conductor for the fan, with the black to the fan switch and a white to the receptacle. I have changed the two switches and matched them exactly as they were before, and changed the receptacle for a GFI. I neglected to write down how it is connected at the light fixture, so I am afraid to connect it wrong at that point. What is the correct way to hook this up?

Answer:

The brown should be connected to the red, the blue to the black and the yellow and Green to the yellow and green. Simple, you will find that the main wiring in houses conforms to that which you found and it is only new equipment that has the Brussels type colours.
I bought a book called Wiring: Complete Projects for the Home by Creative Homeowner. I got it for $5.00. It goes through all sorts of different scenarios and how on the same run you can have two wire and three wire connections. I think it'd be a big help for your current and future projects.
Wow. So, the three conductor from the light to the switch box is serving two purposes. It is delivering feed to the fan switch and receptacle (both power and neutral - on black and white) and it is acting as a switch loop for the bathroom light fixture - so power down to the switch on balck and back to the light on red. At the bathroom light you want the white neutral from your feed to go both down to the switch box on the white of the three wire and to one side of the bathroom light. You want the black from your feed to go down the three wire on black. You want the red from the three wire to go to the other side of the bathroom light. It sounds like you already have the stuff at the switch box under control? Black goes to the bathroom light switch, the fan switch, and the (new, GFCI) receptacle. It's really not correct to daisy chain it from one to the next, you should use a wire nut to connect three little jumpers to the black wire and give each switch/receptacle its own jumper. White goes to the white of the fan and to the receptacle. Make sure that you connect the wire to the Line side of the GFCI receptacle, not to the Load side. You shouldn't daisy chain white either, wire nut the white of the three wire, the white of the fan wire, and a white jumper together and take the white jumper to the receptacle.
