Lets say you combined the strength of every muscle in the human body and then put that strength in each muscle, how strong would you be?Could you lift cars over your head, or even bend steel?
The neutral ground is supposed to be connected to a ground rod, not the water pipes (even though they are often a good ground, if the water is supplied to the house via plastic pipe, there may not be much copper in contact with the earth. A ground rod ensures adequate contact, and there's no chance that a short somewhere in the wiring will cause the faucets in the house to become electrified. In some areas, depending on the building codes, you can install a ground buss and run individual ground wires (green color) to each outlet, appliance and easily accessed lighting fixtures that are near faucets or other grounds (where electrocution might be possible). I did this in an older home which had real 2x4 cross-bracing between the studs, and it was a pain - in some spots I had to drill into the wall and then into the cross-brace in order to snake the wires from the attic down to the outlet. The ground buss itself was wired to the neutral/ground connection (there was already a ground rod) in the service entrance panel.
i suppose it depends on who you are I would certainly be able to bend steel or lift a car but my sister would barely move it. Most, especially those who are very strong, would be able to crush a tin can to the size of a peanut which is not easily done. Chuck Norris would actually have competition and things like punching a small crater about the size of a bowling ball in concrete would be common. Thanks for the interesting question
