As bad as I hate to say this we had a afci breaker that continually tripped sat. Well after pulling all the rec and fixtures we found where when the sheet rockers cut in a box they nicked a wire and after being pushed into the 2x4 box was broken but still touching??Not sure if this was sole cause but we installed everything back having found only this and it remained energized.I guess it could have been the gfci part tripping any comments??
