AC socket/wiring questions
1. Is the Hot wire more insulated than the neutral? If so, why? If
the current is the same at all points in a circuit, the neutral wire
will carry all the current coming in from the hot wire back to
ground...so why have less insulation for the neutral wire?
2. Also, why do we need a third prong when the neutral is already
connected to ground? Is the third prong only there to overcome the
hazards of faulty wiring (hot to neutral socket and neutral to hot
socket)? If so, can't the third prong be wired incorrectly as well
(albeit very rarely)?
3. Is it true that the third prong is grounded close to the building
and the neutral is grounded far away at the power station itself? If
so, why?
