Copper clad ground rod is that considered non-ferrous?

[zappy]

I'm looking at the code. It says non-ferrous can be half-inch diameter. Iron and or steel has to be 5/8 in diameter. Is a copper clad ground rod considered non-Ferrous? Thank you for your help.

Where does it say that?

250.52(A)(5) Rod and Pipe Electrodes.
Rod and pipe electrodes shall not be less than 2.44 m (8 ft) in length and shall consist of the following materials.
(a)Grounding electrodes of pipe or conduit shall not be smaller than metric designator 21 (trade size 3∕ 4) and, where of steel, shall have the outer surface galvanized or otherwise metal-coated for corrosion protection.
(b)Rod-type grounding electrodes of stainless steel and copper or zinc coated steel shall be at least 15.87 mm (5∕ 8 in.) in diameter, unless listed.

I think you're off by an eight inch. But also, a copper clad steel rod is most likely listed and then you don't have to stress over the diameter.
