I built a home nine years ago and used an arc fault breaker for each of the four bedrooms. Recently two of the breakers began tripping with no load attached to them. One more frequently than the other. I replaced the one that was tripping more frequently and the problem involving both bedrooms seems to have been resolved...at least for now. It's been about 5 weeks and nothing has tripped since. Robert Ross July 18 2013, 8:33 am EDT
