So here is a question.
So say I have a 30 amp fuse on the line between my battery and controller and either the battery shorts or the controller does and blows the fuse what good is the blown fuse since there is still a hot line active? Seems like if something happens in the confines of a trailer a fuse isn’t going to help much, the battery or controller will still be pumping juice through the line up to the fuse block most likely melting wire and starting a fire. On my trailer near as I can tell the main lines off the battery to the converter are not fused.
