The circuit breaker was very cheap and didn't work for me. The clip on the back didn't hold when I pulled it out. constantly falls off then i try to put one back, the plastic on the switch broke on the other, and it also fits when you put the cover on, but the performance doesn't last, it's very lost and very poorly made. I am not very happy with it and do not recommend it to anyone. So I had to buy a better one and it worked like a charm.
