    Would there be problem with bending the ground rod of a residential
    transformer at the half-way point at installation? (i.e. the eight
    foot rod would only go four feet underground, the other four feet
    would be horizontal) If so, why?

    Yes, there'd be a problem.

    Why? Because it would violate code, for one. For second, if you've only
    got 4 feet of it "down where it belongs", then you're probably not
    hitting the permanently moist earth that a ground rod is supposed to be
    embedded in, which increases your ground resistance, and reduces its
    effectiveness. Exactly how much of an effect is dependent on too many
    variables for me to make a prediction, but the effects are pretty well
    guaranteed to be "not on the plus side of the ledger".

    Just sink it the way it's supposed to be sunk. You (and anybody that
    ends up with the building after you, if it survives that long) won't be
    sorry you went to that small amount of extra effort.

    Maybe not. I've heard that in some states its imposible to go straight down,
    because the bedrock table is like 4' down! There they are allowed to go
    horizontal! You may have to sink two rods, and maintain less than 25 ohms
    between the rods. Check your local code!
