Thanks in advance for indulging me. I have been reading about the 25 ohm or less for one ground rod or add a second and the various ways to test for compliance but have not been able to figure out where take the measurement. I think obviously one point is the ground rod but what would be the other? Do they all involve driving another rod as a reference to verify the first one? And if you do, does it not then render the values mute because now you have two and you're good to go? Just looking for nudge, push, shove or a kick in the right direction. Thanks
