Barring a local amendment, of course.

Might be worth a phone call to him, pointing out the article. Might be an honest mistake. I'm not sure I've ever seen a stainless rod, myself.

You have proof. 2005 National Electric Code.

Barring a local amendment, he must accept them.

Has the NEC been formally adopted in your area?
 
Grounding rod size

Grounding rod size

The only time I have heard reasoning for the different diameters of ground rod was when the desired driven depth required greater force to be applied when driving the rod or in rocky soil. The thicker rod would have less of a chance of bending. There is no "electrical" reason for diffrent diameters.

The main problem with many inspectors - those present excluded - that they are like the pharasees reading the Book. The understand not but can follow the letter.

If the actual rod does not have a UL or other indicator 'bug' embossed or tagged on it (i.e. ETL, CSA, etc.), then they are not listed. Any listed product MUST be marked as such.

That is the easiest way to determine listing. If they have it on them, you need to show your inspector, because maybe he missed it.

A ground rod is not required to be listed or labeled. The AHJ may accept anything he wants per 110.3(A). 110.3(B) simply says that if it is listed then it must be installed and used in accordance with any instructions included in the listing and labeling.

And before anyone throws 110.2 out read the definition of approved.

Ground Rods are installed to provide a path between the Electrical Service and the Utility's power pole when the Service Lateral Neutral is interrupted.
