I hope I don't get shut off for being off the original subject. The issue of how many ground rods are required at a building or structure supplied by a feeder has been a major issue with me.
Naturally we are assuming that there are no available electrodes at the building or structure and we will be using ground rods that do not meet the 25 ohms.
I maintain that 2 rods are required for any building or structure including a built support suppling a panel for an in ground pool if it is in a building or not
My reason: 250.32 requires that a GRS be installed in accordance with part III of Articale 250.
Part III of Articale 250: 250.56 requires a second rod.
I had that discussion with an instructor a a recent 15 hr class, He dropped the issue.
What do you say?
