recessed lighting problem


I have a recessed light over my shower (shower is never used). When I turn the light on, it burns dim for about 1 second, humes - then the breaker trips. I have changed the switch and bulb but it still does the same thing. Would it be best just to change out the recessed light??

I would not simply replace a fixture in the hope that it will solve the problem. It is possible that you can replace the fixture and not even solve your problem with shorting. I would first identify what the problem is, then go from there.

Something's shorting out. Figure out how to get at the light's wiring box and look for scorch marks.

Quite possible that a standard can was used instead of one that is sealed against moisture. If so the electrical contacts are quite likely corroded and shorting out. A shower light fixture should have a cover over the opening. If it does not then it was not intended for use in this environment.

If it's lighting up at all, a dead short is unlikely.

A partial/resistive short is possible I suppose, but what would be shorting it? Water/moisture isn't usually conductive enough to trip a normal breaker.

I think we should be finding out if this is a gfci or afci breaker.



On second thought, I guess investigating the details doesn't really matter - replacing the fixture with one intended for the use is the solution regardless of what's wrong with the existing one.

Most likely you are correct, but is it not possible that something has happened to the wiring? I have had such a case in my house.

Not all shower trims require the bulb to be covered. The correct bulb will be listed with the trim.
