Were removing a planter alongside my buddes home to widen his driveway.

His ground rods are in the planter. I think we should replace them to a
offset in the driveway. The home narrows a bit partway back.

Ny friend wants to either drive them deeper or pull them out and move
them.

he is cheap

Where does one buy that groundrod driver that fits in a hammer drill??
many electrical supply houses have closed around here and the home
depot person had no idea what I was talking about.

The existing ground is a single ground rod whats the current code?
