Light fixture not on breaker
My house was built in 1998 and we have screened in patio. My husband was going to replace the ceiling fan w/ light on the patio. After turning off all the breakers for the house, the fan and light are still on. There is no wall switch for this fixture either, only the pull strings on the fan. We are obviously not going to attempt changing out the fixture ourselves anymore. I am just wondering if there is something I'm missing like another circuit breaker box for outside electricity. If not, where is this electricity coming from? This also seems like a pretty big safety hazard to me. I think we are the second owners of the house, but I'm not sure. Is this something that the builder should address?
