Interesting electrical find...

We went out to the trailer last night to make Margaritas and discovered the 110 volt outlets and the Univolt wasn't on. I went into the bathroom closet, and sure enough, the breaker was tripped. I went to reset the breaker and POW! it tripped right away. Deciding that the booze was more important at that time and the electrical problem could wait, we retreated into the house with the understanding that I would tackle the problem today.

I went out today to troubleshoot. What I discovered was rather disturbing. The hot wire (black) to the 15 amp breaker that feeds the wall outlets and Univolt had numerous cracks and the wire was actually broken! Luckily, there was enough good meat available in the box to rewire the breaker, but I did have to swap the breaker for the air conditioner side for side with the wall outlet circuit breaker.

With everything working once again, I decided to order an Intelli Power 9200 60Amp converter and a fuse panel to replace the Univolt. I need to add a couple of 12 volt circuits and I don't think the old Univolt can handle much more than what's on it right now.

My guess would be a loose terminal screw attaching the wire to the breaker, leading to localized overheating.

It seemed that there was excessive flexing at one point. There was no sign of burning or overheating, but the insulation was broken and the wire was physically damaged.
