i am confuzed about what the diference between these is. my computer repair book says that a groung just conects to the ground. but i saw in another book these are joined. i have seen braker boxes wired with them joined. i also put one together and they were joined and the inspection passed. i also saw in the computer repair book that they said that the nutral at every pole is grounded. the one box that had them joined is in a house and there is no ground wire or pole at the house. it apears to be a 100 amp box. i have also wondered on polarized plugs the wide blade is nutaral and that is conected to ground so what is the point then in having 3 prong outlets if it is grounded with just 2 prongs.
could someone please tell me what is right.
i have also been confuzed with ac because if it is alternating then wouldn't you get shocked from both the hot and nutaral wires. that is what it sounds like but it works like dc. i don't understand this.
