Hello all,
We recently completed a Solar array on a detached garage and landed the feed in the main panel of the house. The inspector says we must attach the ground to the grounding system of the structure we have the solar array on. And he is right after reading 690.47
So now I just have to run a single ground from our meter to the sub in the garage. The walls are open so no big deal but I was wondering if there are rules for running solo grounds and if they have to be a certain size regardless of what is required. In this case I need a #10 ground. Can I run any #10 ground I have through the studs(they will be covered with sheet rock).
Thanks and any code reference appreciated.
