I think the question is about neutral and ground
Depends on where you are. Neutral and ground are the same in house wiring,but at the breaker panel. But they're treated differently everywhere else. Neutral is supposed to carry current, ground is not. And some protection circuitry, such as ground fault interrupters, use this difference to keep you safe.
