most circiuts out overnight
Last night at about 2 a.m. the electricity on most of the circuits of my house went out. One circuit remained live. I went to the panel and checked all the breakers - they were all on. Just to make sure, I switched them, one-by-one, off and then back on. No change. My neighbors lights were still working. I went to sleep. When I awoke this morning all circuits are working but of course all the clocks need to be reset. What could have caused this? Do I need to call an electrician?
