One of the rooms however, has a strange problem. The breaker is fine until I plug something in turn it on at which point, it promptly trips.
I've replaced the breaker with one that is know to be good, and the same thing happens.
What is causing this? Could it be possible that I have a short from a nail/screw that isn't enough to trip the breaker until electric is called for? How would I diagnose this?
Thanks
Dave
One thing that I have yet to try is to disconnect the outlets at the first outlet in the series. That way I can isolate if the problem is between the breaker and first outlet, or between the first outlet and last outlet.
It's just plain weird that the breaker doesn't trip naturally if there's a short in the line. After all, it's an ARC fault breaker, designed to be hyper-sensitive to that kind of stuff.
