Millercarbon’s first post might sound like a joke (and I assume that was the intention), but there’s an element of truth to it. Ground rods in dry, low quality soil (common conditions) are not ideal. You want a low impedance path to ground and that isn’t easy to achieve. I’ve wondered how you can get around this. Multiple grounding rods should help. Some jurisdictions require at least 2. So would keeping the soil around the ground rod wet. I have to imagine there is at least one audiophile on this forum that has set up a sprinkler system to automatically water the area near the ground rod to keep electrical conductivity with the earth high. I’ve also wondered if putting a ground rod in a river bank or stream would meet code because that would for sure solve the problem.
