Founding Texas-West Chapter Leaders-Retired
Ok collective minds of the HOF,
I've already hit up some folks for advice on this, but I know we have some electricians on the forum that could also weigh in.
We're fulltiming in our 2016 4010RD (purchased Jan of 2016) and been at our park for 6 months. Park service has been consistent and no issues. Temps here have been around 100*, so of course both ACs run all day. Yesterday, about 4:30pm I caught a slight whiff of burning plastic smell. I opened the breaker panel door, and everything was kinda warm in there, but I'd never checked before so I didn't know if that was normal or not. I couldn't pinpoint any issue, and the smell wasn't directly coming from there -- it also seemed to dissipate and then I couldn't smell it.
Today, about 1:45pm, caught the same whiff of burning plastic, but it was stronger. Bent down to check the breaker panel and the exterior of it was warm. Touched the main double 50amp breaker and it was very hot. And the smell was coming from there. I went to unload the basement to start investigating, and that 50amp breaker tripped. Entered the coach and the burned smell was stronger. I killed all power at the pedestal and called my husband, who came home and took the panel cover off the breaker box. He removed the double 50amp breaker, and it was heat damaged (see pics below) The wires looked perfect, no burning at all. He checked all the wires to the breakers for tightness, and the wires to the neutral bus bar.
We removed and checked the 50amp cord connection at the back of the rig, it looked good. We don't have a transfer switch.
We have a portable EMS, which had no errors. Amp draw with all our usual things on, typically 24 on one leg, 22 on the other. Voltage runs about 118-122. Yesterday, I did notice it was a little lower in the afternoon, 113-116.
He replaced the breaker with a new one, and made sure the wires were tight. Reinstalled, all working fine, but still notice all the breakers are still warm to the touch this evening. Especially the two AC breakers (they are on separate legs, we checked). With a thermal gun aimed at the plastic breaker at about 5pm, they were about 114*. The breaker with the W/D which was not in use, at the bottom of the panel, was about 90*. Main breaker was 104*. Now, at 11:45pm, everything is cool to the touch (no ACs running, now.)
Would warm breakers imply something is still not right? What else do we need to investigate?
This is the old breaker, putting my nose to it, it smells burnt.
