    Note he said RCD. Not overcurrent device. Kinda off topic though.

    You're right, my eyes just kind of skipped over the "RCD" part. I should have looked that up.

    I hate to say this but we do it to get night crawlers to the surface for fish bait.

    My Dad did it too. He made us stand on the porch, then let us come out after he disconnected.

    I also remember the wiring he did in the house.

    We lived, and no fires. That’s a measure of success, right?

    The reports of my death are greatly exaggerated.

    try this
    2 rods at 10' apart, 2' deep
    hot to one from a cb, the lower the better
    neut to the other
    amp clamp on the supply
    use a plug so you can disconnect when moving the rod

    start moving the neut rod further away in increments of 5' foot
    record current, you know v= 120, so therefor R

    better yet do this with proper gnd R tester
