Evening John.

First it is not really my position, it is IMO something to think about, there is more than one way to accomplish electrical safety.

I was brought up with grounding and expect it, but it does have some drawbacks.

if there is still enough conduction to trip a GFCI, then there is still enough current flow to shock someone.

I agree 100% with that, GFCIs do not open until current flows.

It seems like it'd be almost impossible to remove the potential for a L-G shock:

In the commercial buildings I work in I would agree with that, a wood framed house, I think it would be very possible to eliminate all grounded surfaces.

With out grounded surfaces there is no possibility of a L to G shock.

This would be a major change in many house systems, phone, cable TV, plumbing etc.

This is not a route I am going to try at this point in my house but I do find it interesting.

Think about the shocks people get in their house.

I think it is safe to say the large majority of these shocks are L to G.

Take away all the grounds and you will have less people getting shocks.

All food for thought, I still will use my grounding type extension cord plugged into a GFCI. [Linked Image]
