A light fixture in my foyer was working fine for years. One day, I turn it on, hear a buzzing noise in the wall, and the breaker trips. I tried a bunch of things, finally discovering the problem doesn't repeat when I replace the fixture (9 60-watt candelabra base bulbs) with a 1 bulb fixture. It wouldn't seem that the 9 bulbs were suddenly too much for the circuit. So do I likely have a problem with my fixture?
take the bulbs out of the fixture, if the fixture shows a short it is bad, there is a possibility that one of the lamps is arcing and causing the short, if the fisture wiring shows open with the lamps put them in one at a time untill you find the problem, Yes I know lamps usually burn open but on occasion the filliment post short and can cause this issue,,,
