What do I need to know about high voltage?
I'm planning on doing a little bit of high-voltage work ( see my plasma cutter question), and I know most of the theory ( except why HV AC in power lines wants to go to Earth ground--any answers to that are welcome. I have my own theories, but...), but I have really no practical experience at all with high ( 50,000 volts) voltage, i.e. what gauge of wire to use, what gloves to wear, how to ground a metal container, etc. Any advice is welcome. Thanks!
