What are 30-amp single pole breakers used for?
I don't know of anything that uses 30 amps on a 120V circuit. Everything I can think of that uses 30 amps operates on 240V (Air conditioners, water heaters, ovens, stove tops, dryers). I don't know why they even make 30A 120V breakers. It seems like something people would only use in place of a smaller (proper-sized) breaker because it's always tripping. It would be a fire hazard in that case.
Years ago some 120v bathroom electric wall heaters ran 10ga wire and 30a breaker .....some electric water heaters and some sump pumps require a 30a single pole breaker.............
