Answer:
My son-in-law is an electrician. I built an addition on my home and did all the wiring myself. Soon after I hired him to replace my breaker box.
He opened the box, grabbed the neutral wires, yelled, jumped back, and said, "What did you do? You crossed a groud and a neutral wire." We checked, he was right.
The hot wire brings exectricity from the power plant. The ground wire will be "hot" whenever an appliance or switch is on because it is completing the circuit back to the generator. The neutral wire (second ground) will be "hot" if there is a short circuit, and carry the current to the earth.
