Do you think it would save me in the case that hot and neutral rubbed against eachother until they one day made contact? would it trip then and stop sparks from flying or not really? (I've checked my wiring while doing it and after and see no reason to believe this will happen, but anythings possible) I'm just curious.
I'm a fire safety/grow safety fanatic so I'll definitely get that.
If hot and neutral ever touched each other or arc'd, a short would occur, which would cause your circuit breaker or fuse to trip. Sparks may fly within that moment... If you're worried about arcs, you can get an AFCI.
But if you periodically check your wiring, this will never occur.
