Ground Clamps — Strap type ground clamps are not suitable for attachment of the grounding conductor of an interior wiring system to a grounding electrode.

Joe, isn't this referring to a strap that wraps around a pipe or rod and is "clamped" to the pipe/rod with a pinch bolt? The following link is for the strap type ground clamp I'm thinking about.

[EDIT} Here is a factory manufactured product that is similiar to the one in the photo. http://ecatalog.fciconnect.com/fci/datasheet.asp?PN=C11CSH1&FAM=491
(I hope these links work...)

Go to the forth paragraph down and it reads;



The 'strap type' clamp in the first part is a strap of perforated metal that you literally wrap around the pipe and install a nut and bolt between to of the perforations to tighten it up. IMO a piece of junk.

The clamp in the picture may very well be UL listed for that use.


Theres that and I was wondering why someone ran such a large conductor to an ground rod.

6 AWG Copper is all the NEC requires.

Good point, I wonder if they also make one for the rod, because this was what I found on the top of the page in your link

Clamps aside this still should not pass as the rod is not flush with or below the surface and you don't have 8' in contact with the ground. (Assuming it is an 8' rod)
