I talked to Paul at SMB Austin. I wasn't aware that the switch was also a breaker, makes some sense now. Guess I missed that at the orientation.
Two things that factored into it tripping:
1. It was 107 Degrees in Dallas/Ft Worth. Got to love the weather here.
2. The switch is low to the floor and kind of in a corner and can probably stand a lot more ventilation.
Also, the fridge was running. Anyhow with all the factors considered the switch may have overheated contributing to it's tripping.
I'm taking the van to Austin on the 17th for some fixes/adjustments and we will address the issue.
