        You don't need HV - large currents can be nasty too.
        The PSUs in some of the VAX 6000/7000 platforms
        are only +5V but can dump 100s of amps. You
        probably don't want to short one of those with
        your ring finger!

        Now for real HV - I was told by an ex-electrical
        engineer - that he watched while someone
        was measuring up for a new HV cabinet with
        a tape measure. The usual metal sort you or I
        might use for DIY. He dropped it and shorted
        out the busbars, instantly melted the tape
        and ended up in hospital with major burns
        across his arms and chest.

        Having been hit a few times by mains (240V)
        voltage, I've learned to be more careful and
        switch stuff off!
