Question

Many electrical plugs & outlets are "polarized", where one of the two connectors is larger than the other one. What statement below best describes these two connectors?

A) The larger one is the neutral one (at ground - i.e., 0 V), the smaller one is the hot one (at 120 V)

B) The larger one is the ground wire that is there as a safety feature in case there is faulty wiring in the device; the smaller one is hot (120 V)

C) The smaller one is the ground wire that is there as a safety feature in case there is faulty wiring in the device; the larger one is hot (120 V)

D) The larger one is the hot one (at 120 V), the smaller one is neutral (at ground - i.e., 0 V)

E) Both wires are identical - the size difference is just there to make sure you don't plug it in upside-down.

Explanation / Answer

Option A is right answer. The larger one is the neutral one because it carries a high current when fault occurred
