Short circuit problem

A few weeks ago, one of my breakers tripped, and kept tripping as soon as I would reset it. The cause of it was an exterior light. When I shut the light off, the breaker reset fine.

I kept the light off and a few days later took off the faceplate to look at the wiring. I did not find any obvious short. I jiggled the wires around and turned the switch on. The light worked and did not trip the breaker.

The light worked fine for another two weeks, and then the same exact short happened with I resolved it the same way.

If jiggling the wires fixes the problem, then what is the real problem and why does the light short out after a week or two?

Buy a new light.

Expansion/contraction can do this.

The fact that you mess with the light, and all is well. Tells me all is not well. Get a new light.

Sounds like a loose connection inside one of the wirenuts.

First suggestion is the best--get a new light.

But, otherwise, unscrew the wirenuts, cut off the first 1/2" of wire, re-strip the wires, and install NEW wirenuts.

Cheers,

Wouldn't a loose conection inside a wirenut most likely cause an intermittent open not a short? Best to just replace it IMHO.

I think you have a nicked or pinched wire. Look very carefully wherever the wires
could be pinched by the faceplate, or where the wires enter the box.

I love it when my clients go to the panel and reset, reset, reset, reset...eventually the wire blows open and then they can pay me to rewire. I have a kid in college. You're the best and I wish there were more like you.

That's Mr. Stripes to you!
