Oh, Another thing is try to get a acorn or jweaver clamp on a piece of rebar. Thinking of swimming pools.
What a joke.
You can turn the screw all day and just wiggle it and they are loose again. Probability has to due with the ridges on the rebar.

Nick. UL does not test the copper or conductor for direct burial it will only test the insulation.

So that brings up another point how many of you will pass a copper THHN/THWN/MTW in the earth from rod to rod? Violation! THHN/THWN/MTW is not rated for direct burial in earth.

Oh...I will send in for a formal to NFPA.

Bare copper is judged to be "suitable for the condition," so therefore it is not required to be listed as direct burial.

Scatter through the code and it says the same thing about uninsulated neutrals.

Mike you should start that in a new topic, that is why I did not bring it up here.

Good idea Ruben. I will be at the grounding seminar tomorrow and will also present the question to Mark Ode and John Minick, but I am sure I know the answer!!
I am glad to see everyone in lively banter again after that long cold winter.

Well Paul how did you like John's answer to this problem

A good time was had by all at the grounding seminar on Saturday. I want to thank Dick Widera, who while still suffering from food poisoning still got everything going and did an excellent job. I approached John Minnick before the course started with the question relating to using Table 300.5 with the related table to enforce the protection of the GEC. John's answer was that nothing in 250.64 references that but he see's nothing that would stop you either. The main point was that 250.64 (B) states A 4 AWG or larger copper or aluminum grounding electrode conductor shall be protected where exposed to physical damage.So this leaves the method up to the AHJ. He saw nothing wrong with using 300.5 but would not use the 24 inch depth. He went on to say this discussion has never come in code panel 5 all the years he has been there, but it is a worthy for future consideration. Paul, did I forget anything?

Yea, He also said it depends on whether or not you liked the contractor
