I want to know if I can add a GFCI combo switch from an existing light. This bathroom has no outlets. I was able to put in a regular outlet for the time being. I added wiring from the light to the outlet. I bought the GFCI combo, but am so confused if I can even use it with the existing configuration. The power is coming from the light source. Any thoughts would be appreciated. There are 3 wires, black, white and ground.

Can not be done without another wire.
Of course I'm guessing that you mean a switch/gfci combo.

if power is coming from light, u will need the black and white just to switch the light. so if its possible to get another wire down, or a 3 wire ur all set.

So if I can pigtail a black and another white wire it should work? How does that configure for the GFCI? Do I use the switch wires that are attached to the GFCI? I just might have to fork over the dough and get an electritian. I am at my wits end. Thanks for the input, I really appreciate the quick replies guys.

Yeah, a switch, GFCI outlet. So, you mean another black and white wire, pigtailed from the light?

jbfan 11-12-2012 07:43 PM

Just another wire.
What you need is a hot to feed the receptacle and switch, a neutral to feed the receptacle, and a wire to return power to the light when the switch is turned on.

So, pigtailing would work? Or a completely new wire connected to the light? Sorry, if I sound like a dunce. I don't give up easliy. I guess how you get the power shouldn't matter. Thank you so much for your quick reply.

A new wire to the light fixture.

jkanketell 11-12-2012 08:14 PM

I already added a new wire to the light. So a second one too? Smacks head, yeah I must be a dunce. LOL By wire I mean a 12/2 bundle of black, white, and a ground. thanks

You need 3 "conductors" study what jbfan posted

jkanketell 11-12-2012 09:28 PM

are the three conductors name black, white and ground? Please s p e l l it out for me, I am tired of all of the diagrams I have been studying. Thanks.

Ok here goes :)- pull out the 12/2 (easier to explain guys) pull a 12/3- at light u will put "hot" wire on black of the 12/3 - at sw/rec make pigtail on black with 2 ends on it, put one on the sw and one on the rec - put white on rec - put red on sw - at light put red on light's black - put white to white

jkanketell 11-12-2012 10:23 PM

Okay it is getting clearer, sw meaning switch? and rec meaning? thanks

tduncanlu1077 11-13-2012 07:25 AM

Rec meaning receptacle
