Good wire for bathrooms...


I'm renovating my bathroom and have some Romex 14-2 WG, NM-B. I will be wiring my vanity lights and three switches, a GFI outlet, and a new bath fan.

I've read that I need different wire, that what I have won't work in bathrooms.

Comments...yes, no...what to use. I appreciate any help that I can get in this area.

Thanks, Ed

The #14 can work for the lighting and fans but cannot be used for the required 20 amp circuit to serve the GFI protected receptacle. You would need #12 for the receptacle circuit.

You need a 20A circuit for the bathroom GFCI (the lights can be on a separate 15A circuit). 14-2 is rated at only 15A. You need 12-2 for the 20A circuit. That being said, NM-B cable should be fine for a bathroom as long as it is properly rated and secured.

No, just a 15-minute delay between me typing a message and actually clicking "submit."

Thanks for the info...gonna get some 12-2 for the GFI ciruit.

I take it that I'm going to have to run a new line from the box and a 20 amp breaker...12-2 is 20 amp...yes?

I have 5 GFI outlets in my house...and all are on 14-2...hmmm...do they all need to be changed to 12-2.

Thanks again...this forum has been really helpful.

More recent editions of the electrical code have called for 20 amp circuits for bathrooms, kitchen receptacles and laundry receptacles. Before 15 amp circuits were common, but with the increased use of blow dryers and curling irons they become too small.

Yes, #12 for 20 amp circuits.

The code is not retroactive so you can leave the old circuits as is. If you make changes to them you would need to upgrade to the newer standard.

its always a good idea to go code+1. IMO, 14 guage wire is too small for anything running 110v
12-2 throughout, and #10 for heavier appliances. also NM is outdated.

good luck with the reno

14 gauge is also too small to use on my car battery circuit going to the starter, yet it is only 12 volts. So where can we use 14 gauge?
