For the electrical gurus out there, sorry for all the questions.
Can the service neutral be considered/used as the GEC in any situation? I had an electrician tell me that in our main county, the AHJ considered the service neutral the ground when the water line servicing the house is plastic.(assuming I didn’t butcher what he said).
If this is the case or something similar is correct, how is this possible if the service neutral is carrying a load?
I know they try to balance the panel, but how realistic is it to get both phases carrying a similar load so that the service neutral is at 0 potential?(again, assuming I didn’t just verbally butcher that as well)
Is this a cop-out by the AHJ and should an inspector call out the lack of a GEC in a panel if this is the setup, assuming the panel isn’t connected thru metal conduit to a GEC at the meter?
Thanks for any clarity you can provide and I apologize if I have abused/misused any principles, theories or terminology in the writing of this post. I still haven’t decided if working on eletrical systems is more dangerous than asking questions about them on a forum.
