The original project was to undo some haywire installed by a previous
owner for a battery charger. I also need to run in a new circuit to
an unused breaker on the AC panel.

Whatever the cause of neutral and ground being tied together
somewhere, I suspect it has been that way for quite awhile.

I'm probably missing something but I don't see too much immediate
danger unless we end up somewhere with the shore power backwards.
That's dangerous in any case.

What are the other risks?
