What Does Trailer Battery Circuit Breaker Really Do for Trailer Wiring
Updated 04/16/2020 | Published 08/19/2016 >
Question:
I have a new deep cycle battery installed. I attached pos/neg wiring to terminals and theres no power. I have isolated the problem to the In-Line Circuit Breaker - Perpendicular Mount Bracket. That part is completely corroded very old. My question is - why do I even have that part in the wiring? Cant I just cut it out and wire positive straight to battery? PS: I do not use my car battery to power interior trailer lights.

Circuit breakers are a great way to shut down a circuit if there happened to be an overdraw that would otherwise get the wiring so hot that it would melt or even worse catch fire. They also would save any accessories attached to the circuit from getting damaged as well. For the short term you could bypass the breaker if you need to get the trailer back on the road ASAP but I would recommend replacing the breaker as early as possible. For a 40 amp breaker we have the # 9510.

My mom has a travel trailer that has a slide out.. the thing is we have it plugged in for the lights n we turned off all the other power switches so the water heater doesnt run n so forth.. but theres something under the sink that turns on n it looks like the amp converter I think.. but it hums wen it comes on n it leaves a smell like burnt water or like something needs water.. how can I run the interior lights without that coming on.. Im concerned cuz I feel like its gona cause a fire or blow something out.. please let me no wat i can do to avoid this all.. we dont haul it anywhere its just posted on her property n I stay in it from time to time.. n I dont use the frig the stove or the water in it.. I only need the lights..
