Not changed yet. There is a new code requirement for mobile homes that
have a ground added to a dryer cord, but it isn't required for anybody
else. btw, you'd never have H-G-H, you always have either H-N-H or
H-N-H+G, where G does to chassis. Neutral bonding to chassis is falling
out of favor, and not permitted in portable devices anymore (for like
the last 20 years). There is good reason for this too, as I was nailed
once from this due to a joker reversing hot and neutral by mistake.

Whole-house GFI is unheard-of in the states. It may be legal, but its
not done. I would find it to be a mammoth pain in the ass. I've often
tripped branch circuit GFI's, I'd be pissed if I killed my whole house
by doing that.

I want to try the new AFI's invented by General Electric (Arc Fault
Interupters). They can sense small arcs from things like loose
connections. It's very easy to start a house fire from a loose
connection arcing for a while and making things hot.
