Hi. What's the typical way to connect two ground rods to a meter panel ? I borrowed a commercial ground meter, and measured 50 ohms at my meter panel. If the resistance measures above 25 ohms, the NEC recommends driving a second ground rod, at least six feet from the first one. When connecting the ground rods to meter panel, is it better to connect them in series, or run a wire from the meter panel to each rod ?
Thanx.
