    I sent in a link to this thread. He can decide if the wording needs to be changed.
    They say I shot a man named Gray and took his wife to Italy
    She inherited a million bucks and when she died it came to me
    I can't help it if I'm lucky

    does 250 require two electrodes? Or is it their requirement to be below a certain ohms that causes the need many times for two electrodes? I mean, shrink-swell soil, from what I have heard but have no actual knowledge, may cause you to need to go to a ring system of electrodes to effectively keep your ohms down, in all water levels in the soil. Unless I read that report wrong in the nineties in the Richmond Crimes Dispatch when they were going nuts over shrink swell soils in Va, and NC.

    It's like this-- Many areas of the country it is impossible to get 25 ohms with 2 rods and other areas it may be possible. If you could get 25 ohms you would have to prove it which would mean meeting the inspector there and doing the ground test while he is there. That cost too much time so it is easier to just drive 2 rods.

    OK.. Just wondering. I mean, I have seen it happen where four ground rods did not get below 50 ohms, with number two wire bonding them together.
