Am EC friend asked me this question last night, and I've been pondering it:
Let's say you have a situation where the service entrance conductors are partially in Greenfield. They come out of the back of the meter pedestal, through 2 ft of Greenfield into a pull box in the basement, and then down to the panel a few feet away in EMT. (The pull box is a splice point to make the house solar-ready via a line-side tap).
Are you required to use bonding bushings on each end of the Greenfield, and pull the #4 ground into the meter pedestal? I say no, because it's ahead of the bonding point in the main panel, and the neutral is bonded to the can in the meter pedestal anyway. What does the green wire do there, and is there even a factory-provided lug to land the green wire? I did suggest he pull the #4 green into the pull box to make everyone feel better about having a good ground if/when the homeowner adds solar in the future.
Thoughts?
