(This is a carry over from the Mike Holt forum on the same topic.)
Here is a common situation. A residence has a 400 amp service. It is a rural setting, so there is no metallic water main and meter into the house. (It is plastic coming from the well pump). The only metalic piping is the interior water system.
In this situation, the GEC to the made electrode is not required to be larger than #6, correct? Or must it be #2 copper (assuming 3/0 copper parallel for the service), since there is no metallic water main?
It is my understanding that the only purpose of the ground rod is to direct lighting strikes to ground.
