If you were to experience a power surge at home, would anything come through the third prong hole (ground)?

Answer 1

No, the power surge would only affect the other two prongs and more that anything the black wire or hot prong. The green wire or bare wire, should still remain at ground level.

Answer 2

It's possible. A circuit going to ground could do it if the grounding electrode isn't working properly. A lightning strike to earth nearby could do it. I've been shocked by a backyard lightning strike while installing receptacles in a new house with no power hooked up yet.

I suppose technically that wouldn't be a 'power surge', but electricity CAN get you via the ground wire.

Answer 3

I agree with your first answerer but would add the following. It is true that in 120 vac (volts alternating current) that black is hot, white is neutral (often called common) and green or bare is ground. One of the first things I learned is that one never goes by color. One believes one's meter. When dealing with higher voltages such as 240 vac or 480 vac there is more than one hot wire. In industry, vdc (volts direct current) is found. Usual 240 vac loads in your home: A/C, Stove, ect.
