Anyone got any high-current/low-voltage horror stories they'd care to
share? You know; where your messin' about with a car battery or
something like that and forget to take your watch off or whatever.

I did once work with this sort of power, at a company which was making
superconductors. We had to test various samples at high current/low
voltage to determine some of the properties, while they were submerged
in various liquified gases.

One project involved setting up a two-module 1000 watt DC power
supply. I "wired" them together using copper bar stock 1" by 1/4",
bent to fit the terminals, and plated with silver for lower contact
resistance. The connection to the samples was with 2 ought welding
cable, which was about 1-1/8" in diameter with insulation.

I have also worked with high voltage RF up to 20 kV, but that is
another story.

The general rule is when you are working with KIL-o-amps, KIL-o-volts,
or KIL-o-watts, is to make sure you don't get KILL-ed.

Happy trails,
