Had an inspection yesterday that has me wondering.


Ground rod has an acorn clamp with a red wire being used as the ground wire. It goes underground.

The ground wire coming into the panel is black. It is tied into the neutral bus bar.

Ground and neutral are tied together properly through the panels bonding strap.

Every wire on both the ground and the neutral bars is white.

Other than the wire colors being used, is this an issue?

thanks.

Jeff…


Other than the colors which are bad enough and would seem to indicate homeowner wiring and possibly other problems, I would be concerned about how the red and black grounding conductors are connected. If the ground rod is THE grounding electrode, then the GEC should not have any splices (unless made with an irreversible compression fitting). That would seem unlikely. If the ground rod is supplemental to the water piping then the GEC connection to the piping is supposed to be accessible. As you didn't mention it, I assume you found no such connection.

I believe you have more than enough unknowns to call for Sparky FE.

Just my take...as usual, the real electrical gurus here wil probably have a better opinion.

I agree entirely ![icon_smile.gif](upload://b6iczyK1ETUUqRUc4PAkX83GF2O.gif) , I would want to know why, where and how this splice was made.
