and has worked every time the issue of GFI-but-not-circuit breaker has come up.

Kory, I'm not sure where you heard about this, but I'm glad you brought it forward. The explanation is a bit more complicated than most folks care to wade through, but it is accurate.

Anyone who is finding that a GFI in a campground or garage is tripping, even when all the breakers in the TM are turned off, should at least read the intro to the writeup. It can save a lot of frustration and wasted work.

I know....... that's why I didn't say "dead short". The neutral element just reacts the grounded tank. That's why the converter can get confused also because that make the water heater look like a dead battery.
