Neutral and ground are the same thing at only one point in your house. A
second box in the same building with neutral connected to ground would
violate that safety rule.

Neutral carries current during load. Ground should never carry anything in
your house. Two ground points can cause the ground wire to share load and
cause many different problems. Simple example: You don't want current
flowing through your tub frame to the taps when you are standing in it.

No, the neutral is still the ground.

BTW if you attach a meter to the hot and neutral you'll get voltage.
Attach the hot and ground and you'll get voltage.

My house was wired so that neutral and ground are one and the same...
My second box was not allowed by code to do that.
It had to have neutral and ground seperated...
No idea why, but that's code.

I have my whole shop on GFI, I don't trip any on startup.
GFI is specifically for ground fault.
So if you are tripping them, either the gfi is bad or you have a problem
with your end equipement / or wiring of the equipment.

Ok, one more question. What if it's just a two pronged plug (no ground
plug) as is the case with that fan in the bathroom that I mentioned?
Could a two pronged plug produce false GFI trips?
