re a question about vac outlet wiring in article apr ecsvax uncecs edu crisp ecsvax uncecs edu russ crisp wrote hello i m considering modernizing some old wiring in my home and i need a little advice on outlet wiring several outlets are the old two prong type without the ground naturally the wire feeding these outlets is without the ground wire i noticed at the fusebox that some circuits have the with ground and that on these circuits the ground wire was tied to the same bus as the neutral white wire so here s my question it seems to me that i d have the same electrical circuit if i hooked the neutral d d d d d d d d d d da jumper from the neutral over to the ground screw on new three prong grounding outlets what s wrong with my reasoning here first it will not pass a national electrical code inspection secondly the neutral wire is current carrying and the ground wire shouldn t be or only during a fault condition the reason the neutral and ground are tied together in the panel is the tranformer on the power pole has a grounded center tap secondary with the grounded center tap the neutral this gives v to neutral ground from each side of the transformer and v across the transformer so in effect the neutral and ground should be at the same potential mark e kilpela email mkilpela mtu edu michigan technological university school of technology
