That makes sense. I recall reading some time ago that "properly wired" campground pedestals will have two service feeds, one dedicated to the 50A and another to the 20A/30A breakers.

Knowing that, I'm still trying to figure out why the GFCI (or potentially the 30A breaker) would (or could) cause an open ground situation leading to the hot skin, and why that wouldn't show up when testing the grounds.
Am I misunderstanding something?
