mystery of the tripping breaker
Comments (8)Something worth checking: When I was wiring my house, a couple of times when I pushed a switch or outlet back into the box after connecting it, the bare ground came into contact with the hot screw on the device. The tricky thing is, you can pull it out of the box and try the circuit and it works just fine because the device is pulled away from the part of the ground that is touching. Then, when you push it back, everything tends to go back where it was, and it shorts again. After a couple of episodes of this, I became more careful about watching where the ground goes when I push things back in the box. This was all Romex. If you are using conduit, you might not have bare grounds. In that case, I'd check the hots for cut insulation where they enter the boxes....See Morecircut breaker trips everytime I turn off lights
Comments (24)Same issue here, only my breaker box is 25' from the door of my crawlspace and I got tired of going under there and quit for today. Just left the light on while the switch says off. I am sure I wired the new light the same as the old one was wired. It's the end of a 3 fixture string. There are 2 black, a white, a grey, and a ground. The 2 blacks were with the black on the fixture. The white and grey were with the white of the fixture. The ground to the ground. I mean, that's simple, right? How could I have messed that up? Now the switch is in the off position and the light is on. Turn it off and trip the breaker. Keep the switch at off and reset the breaker and it trips immediately. I plan to undo and redo it tomorrow, but I don't fathom any new result. Any thoughts and/or advice? I am not a professional but I do reviews for Kichler so I've installed and/or replaced more ceiling fixtures than I can count and thus has never happened before. Thanks- Karen...See Morearc fault breaker not tripping when wires are burnt in bedroom
Comments (7)If the wire nuts were melted, the iron certainly isn't your problem. That particular junction that melted was creating heat - and lots of it. Not everything that creates heat will trip an AFCI - and your iron is a good example. The AFCI is measuring current wave forms and comparing it to "normal" waveforms (like turning on a light or plugging something into an outlet.) If the wave form exceeds the normal in speed and intensity, it trips the breaker. The thing that causes heat is a combination of current and resistance. That could be in the form of the resistance of air (as in an arc) or gunk. Or it could be from higher current flowing through a wire that wasn't designed to handle it (as in a bulb too big for a fixture.) Also, ACFI's break. Have they checked to see if it is actually working?...See MoreSwitching a double breaker to a single breaker
Comments (7)" i would reccommend just buying a new 15 a breaker and a filler plate." Not really worth the trouble. Use one side of the two pole breaker and leave the other unconnected. If you need another 15 A circuit, use the other side of the two pole. If it is annoying having BOTH circuits turn off when EITHER trips, purchase two single pole breakers at that point....See Morebigbird_1
