Gentlemen- as usual these threads seem to drift. That's not a bad thing because it brings in good information. BUT- The original post only talked about rods.
They sure do but I did not see the actual subject drifting to much here.
two rods with a jumper (#6 awg cu) between them would constitute a grounding electrode system satisfying the code minumum requirement unless, there were other electrodes present. That said- a single Maximum size 6 AWG cu run to either rod gets the job done.
I agree.
