So after reading this page, I'm pretty confused. This seems to only make sense if the circuit is DC, right? If the circuit is AC, then the polarity is flipping constantly, so wouldn't it mean that the side of the circuit with the ground is only safe half of the time? I know that that doesn't make sense, but I don't understand what I'm not understanding.
Also, my father is an electrician, and we were talking about electronics today, and he said "unless there's a fault in your circuit, you can NEVER get 'bit' off the neutral line because there's never power on the neutral line". This also doesn't make sense to me; wouldn't both sides of the AC circuit be "hot" half of the time? I think I must be missing something pretty fundamental here but I can't figure out what it is.
