The interesting thing about a GFI is that it doesn't actually need a ground
to do its thing. It senses an imbalance in current between hot and neutral,
or for a 240v GFI, between the hot legs and/or neutral.
If any portion of the current drawn from a hot leg isn't balanced by a

This is, unfortunately, a "common" misconception. (So to speak :-) )
Yes indeed, the ground and neutral conductors are at the same potential.
The two conductors serve very different purposes, however.
If you connect the neutral conductor of an appliance to the ground
conductor by mistake,
Yes.but RV's can have a weird problem. When operating in stand alone
mode (i.e. self supported and not connected to the grid) they often act like a
house in that the inverter/generator makes its own 120|240 and therefore the
ground and neutral are often bonded together (at one

Ground and neutral are bonded together at only one point in your house.
Usually that's at the main panel or main disconnect. From that point on,
ground and neutral are kept totally separate.

I thought you could mix ground with neutral? Not sure I know what I am talking
about. Two of my 3 AVCON EVSE use neutral. Lawrence Rhodes

My extension cord power company said they won’t do anything unless it hits 7%
over 240V and since I’m near the substation , I see it 250-252V so the folks at
the end of the line miles away aren’t too low. Most local pole peg
