Wiring advice: switch outlet and overhead light

I have a basement bathroom I am fixing up and it needs some wiring improvements. Currently two boxes, one for light switch and one for gfi outlet, plus one over head light box. Black White and ground wires running from overhead to upper outlet box and another from outlet box to switch box. Then source wires ending in outlet box.

Thr main constraint is the absurdly high placement for the upper box for the outlet because of short length of the power source wire in that box (I am okay with it though because it's a basement bathroom). I'd like to put a gfi there.

I can't figure out how to wire it all properly. Any advice would be much appreciated. Thanks

Welcome to the forums.

Is anything already existing there ?

You have a switch box and you are installing a GFI receptacle above it.
The cable from the light should go to the switch box.
The power coming into the room should go to the GFI receptacle box.

Maybe this will help. This is what is currently set up. Visual helps over the explanation. All have ground by the source wire carrying the load, which just has two.

Keep in mind that a fluorescent light can have leakage and trip a GFCI.

Moot point since best practice is to not put the lights on the GFCI.

Diagram based on 2011 National code. Previous code cycles would have allowed 2-conductor cable between receptacle and switch in this example with the white conductor relabeled as an ungrounded conductor.

Good picture.... thanks Ray.


You've got a lot of wires in the receptacle box. Makes it tough to get a GFI in.

Go directly from the switch to the light.

Much cleaner but the O/P asked for:Light from receptacle box.
