Reno- The '02 NEC said "if available" and the feeling was that if it was not exposed it was not available. The '05 NEC says "if present" so this makes it mandatory to include it as an electrode and include it with any other electrodes that are present as the Ground Electrode system. My question had to do with the fact that if they weren't loug enough did we need to tie them together?
