I am confused.
While working for an electrical distributor for over 5 years, we sold the acorns for 5/8 ground rods and the larger clamps which you have shown for 3/4 ground rods. I had the understanding that the acorn style clamps would not fit on the 3/4 ground rods.
If I am reading your post correctly, the clamp that you have shown is not allowed to be used on ground rods.
While I did not know they were not allowed to be used on ground rods, my question would be is what clamp is used for the 3/4 ground rod?
I know this clamp was used for bonding the panel to the water pipes, but I also had the understanding it was ok to be used on the larger diameter ground rods.
As a matter of point, when I purchased my first home, I installed a new 200 amp CH series panel with a 3/4 X 10 copper ground rod. Since I could not use the acorn clamp, I used one of these. The inspector that inspected the service did not say anything to me when he saw it, and I know he saw it, it was directly below the electric meter and above the ground, since they are not rated for direct burial.
