Hi All.
When installing a sub panel at a garage using 4 6 awg's and driving a ground rod bonding it to the grounded conductor at the sub panel, can this ground rod be considered part of the grounding system at the house? Would it still be necessary to drive a second rod at the detached structure when there are 2 more at the house service location? For the longest time I have driven only 1 untill a recient inspection failed for not having a second at the garage. Am I missing something? I want to be sure I install them correctly.
Blessings,
Mark
