Electrical – What are the proper steps needed to install a grounding rod

electrical-panelgrounding

We had an electrician friend upgrade our service panel and install grounding rods. I've read that you have to drive the rod flush to or below ground. Please see these pictures. Is this okay? Do I need to be concerned?

The conduit has copper on the inside and there is bare copper at the connection point of the grounding rod.

Also, do I need to find the water meter so that I put a jumper across it?

Best Answer

The rod must be at least 8 feet in the ground, and should be below or flush with the ground level. If the electrode is above the ground, it has to be protected from physical damage.

So if the rod is 8 feet in the ground, you'll simply have to protect the aboveground portion from physical damage.
