I have an older home that has an upstairs bathroom protected by a couple of GFI outlets on the same circuit. Both GFI outlets are in the bathroom.

The circuit is supplied from a normal 15amp breaker in the main distribution panel. No problems or tripping have been observed.

I'd like to protect this circuit from arc faults in the circuit from the main panel to the bathroom. If I install a 15amp AFI breaker in the main panel would that breaker work with the GFI outlets or would conflicts occur?

I'm not a pro, but I don't think AFCIs are required for bathroom circuits. Why would you want to do it? Those breakers are ten times the cost of regular ones. Fortunately, when I built my house three years ago I only had to have them for the bedroom circuits.

Right, AFCI's are not required by code for bathroom circuits already protected by GFCI's. As stated in my original post I live in an older house. The house was built in the 1920's but was not electrified until REMC's were established in the late 1940's. I've replaced most of the wiring over the years but this particular circuit is original. As you can imagine with older houses a mouse or two will find its way in every so often and I always wonder what they are chewing on before I can get the traps out.

So I want to protect this circuit from arc faults. $35 bucks for an AFCI is pretty cheap insurance IMHO.

Even with "newer" old homes. My house was built in 1984. When I had the load center replaced last year I included 9 AFCI's for most general lighting/recep circuits even though none were required. I discovered an overhead light using the ground wire as its return path -- an issue I may have never discovered otherwise....
