Breaker turn on but lights don't
My lights in my kitchen along with my washer,and a/c all went out one day. This has happen before, and all I needed to do was go to the breaker box and flip things back on. Well it's done it again but this time when I flip the breaker they don't come back on.. I was wondering if it is possible that one of the wire on the outlet became lose or maybe got blown off with a surge? Because you must understand that my stove, refrigerator, washer, and a/c are all on this breaker.. (hey I live in NYC) if what I'm thinking is true, wouldn't I just have to go around and find the lose wire in the outlet attach it and things should work? Plus I can't really recall if it a 15 amp or 20 amp breaker but I do understand that what ever it is I should upgrade it right?
