So I got a good one today, and failed the first inspection in who knows how long. (I cant remember the last...)
Here's the scenario: An addition to an existing house, with a seperate sub from a new main panel, mounted to a fence.
The feeder to the addition contains a full-sized (for the service) ground. But only done as an electrode for the building. I didn't see, or wasn't paying attention to a copper water line at the fence to the irrigation. But apparently there is water available at the fence.
As for the water line at a fence that the main panel is located on - No one knows if it is a branch of the main water, or a branch from the existing house to the irrigation. The Inspector wants it as an electrode to the MCOP.
So the question is, should it also be used as an electrode for the main panel?
