Cable with red – 24 volts, black 120 volts, white 0 volts (from breaker)

If that cable is truly coming from the breaker, there should be two breakers. One for the black wire and one for the red wire.

You're good - lights in the hallway are working.

OK, put a wire nut on the red wire in the power source cable in the box behind the medicine cabinet.

At the switch box, connect one of the black wires from the combo switch/outlet to the black wire of the 3-wire cable with a wire nut and add a pig tail (a short piece of black wire). Connect the other black wire from the switch/outlet to the red wire of the 3-wire cable. Connect the white of the 3-wire cable to the silver (top) uncovered screw of the switch/outlet. Connect the white of the 2-wire cable to the silver (bottom) covered screw. Connect the black pig tail to the brass (top) uncovered screw. Connect the black of the 2-wire cable to the brass (bottom) covered screw.

The red from the power source is connected directly to the fixture ad you said before if I cap the red from the power source then won't the fixture be getting no power or did you forget to tell me to attach the red from the loop back to the black from the fixture?

[hkstroud]

did you forget to tell me to attach the red from the loop back to the black from the fixture?

Yes, possibly. The red of the switch loop should be connected to the black going to the light fixture.

Winner!!

You are the best Harold even tough I will never get to formally thank you I truly cannot thank you enough!

You kindness and attentiveness to a complete stranger saved me from my angry wife and probably injuring myself.

Well wishes to you and if you are ever in Rochester NY please let me know I owe you a cold one!

Should I worry about ground in the outlet?

[hkstroud]

Does the 3-wire power source cable have a ground wire in it.

[jasonbran16]

Not in it - its on the outside of it - comes in the wall - connects to the light - then goes into the wall with the loop connection and doesn't come into the light switch box...

[hkstroud]

Then connect all ground wires together behind the medicine cabinet. Connect any ground wires in the switch/outlet box together and to the outlet. If there is not ground wires in the switch/outlet box nothing you can do to ground. The GFI provides more protection than ground.

Congratulations and good luck.

Harold - possible for you to tell me how on this existing setup we would setup a fan to remove steam during showers.

My dad wants to come up and do it 2 weeks from now since we just completely refinished the bathroom by painting all of the walls and refinishing the tile...
