Right, the breaker that was feeding the camper, and the shop fridge, and the shop A/C. Had it been the breaker inside the RV (The one feeding JUST the A/C) We would not have this thread. It took all of them together to create the Inductive kick that fried you.
The moral of this is to add a TT-30 circuit to your shop for the RV, dedicated breaker (just one) and outlet, nothing else on it. Or better yet, put in a 50 amp outlet for the RV, that way when (not if) you upgrade,,, all set. 50's take a dual-ganged breaker, 30's a solo breaker.
