Did he use a double lug or put them both under the same lug? What size wire? Can't parallel under 1/0. I wonder if the equipment grounding conductor is 1/0 or largerActually inspected the same thing yesterday on a detached garage. New service with 4-wire, installer used neutral and grounding conductor as parallel. Connected to grounding lug in meter base(utility does not ground from meter base) and connected to terminal in load panel. He said the guy at the supply shop had a short piece he would give him. Less then 2 feet total distance.
Or only connect one end then it is still a grounded shield of sorts.Just cut off the equipment grounding conductor
That is what I suggested in post #2Or only connect one end then it is still a grounded shield of sorts.
Sorry, I did not see your implied "just one end" in there, next time type a little slower.That is what I suggested in post #2
I read yours wrong thought you meant disconnect the egcSorry, I did not see your implied "just one end" in there, next time type a little slower.

Good point.Even if #1/0 or larger the two conductors in parallel would need to be the same size and have the same characteristics, like both being insulated or bare.
so bottom line is nothing prevents using 4 wire for 3 wire application if i leave both ends of the spare wire disconnected and taped up?
