Hey everyone... i am in a residential wiring class right now and am having trouble understanding some basic stuff. we have not gotten in too deep yet so i would like to make sure i understand this now then get even more scrambled in the head.
okay what i have going on is identified grounding wire and grounding wire... what is the difference as easy as can be taught to someone...
if i dont make sense on my question i am asking from what i understand is there are neutral grounding wire, idientified grounding wire and unidentified grounding wire...
i understand that the unidentified grounding wire is the hot wire.
what i dont understand is the difference between the grounding wire and neutral wire???
what i dont understand is why my book says neutral is neutral but can hold a voltage...
what i dont understand is that there is 3 phase and single phase i understand it comes from the transformer from the power company but if there is 2 hot and one neutral why is it that the neutral can have voltage on it ?
