Hello,
Is it ok to use #2 bare stranded copper for a ground rod?
Thank you,

Number 6 is all that is needed but many here believe stranded is okay. In one of our jurisdictions it will get turned down based on 250.62
Article 250.62
The grounding electrode conductor shall be of copper, aluminum, or copper-clad aluminum. The material selected shall be resistant to any corrosive condition existing at the installation or shall be suitably protected against corrosion.The conductor shall be solid or stranded, insulated, covered, or bare.
What is there for them to turn down?
They believe that stranded isn't suitable protected against corrosion since there is more chance of corrosion between the strands.

even though the code specifically says stranded is OK?

Perhaps because the minimum size for a ground ring is #2. Larger strands would take longer to corrode...???The question remains as to whether or not stranded copper to a ground rod need protection. It seems they allow a ground ring in the earth that is stranded so why not to a rod.
