Tool size?

The best intentions .... again paving a path to Hell!

"Driven." Originally placed there to deny the technique of using a cup of water in the hole to hydraulically bore a path ahead of the rod, or a hose to flush dirt out of the hole to make rod passage easier.

Now we're debating eactly what other techniques may be allowed. Ugh!

As with the 'great sheet metal screw debate,' I think the code panel went down a blind alley with this requirement. The only way out is to reverse course, and remove that word.

Don't you know cutting ground rods is a "don't ask, don't tell" issue?

While we're talking about this, suppose the rod of whatever length is tested and found to be under 5 Ω or even under 1 Ω. Is this OK?
Apparently not.

it says the rod has to be driven.

would you could do is drill the hole, fill it with dirt and drive the rod in. but you can't fill in around the rod with concrete IMO. maybe you could "drive" the rod through the wet concrete. I don't recall the exact wording, so I don't know if it says you can drive through anything other than earth.

I'll have to read up. Code does mention "concrete encased electrodes".

Another way, Blast away 10 ft of topsoil, rock, etc. Bulldoze down as far as possible. Screen rock from dirt removed, put it back in place. Grind up rock and sell for rock gardens. Bring in loads of topsoil or fill dirt to get back to original contour. Then drive ground rods. That is "driven electrodes". What are we up to now, about $20,000 including explosives?

Lighten up, don't you know a joke when you see one?

I've heard people talk about using a hose but not the cup of water. I don't see what would be wrong with either one. Pound the ground well with a hammer all around. Soil will close up around the rod.
