We were rewiring the utility and other switched outlets (all 110) on an ION IMPLANTER. The IDIOT that did the work managed a hot / neutral swap and the ENTIRE CHASSIS was HOT. Of course, he worked nites and was GONE for the next 2 weeks on vacation.
I've been around a LOT of high voltage. In E-Beam metals evaporation, the voltage is around `13kv.
I'm linking the manual. You'll see a FULL POWER Triode in the circuit. This was a WATER COOLED device and required a certain water purity since it was part of the circuit. A lot of current, too.
Ion implaneters have a 20kv Extraction PS which gets the ball rolling and the ions into the acceleration tube. Which is up to 200kv. The Glassman Power Supplies were mostly AIR as an insulator.
Wafer Fab, where I worked as a process and maintenance technician (2 differetn 'careers') was a dangerous place to work. All sorts of nasty chemistry.
So you don't have to convince TOO hard for me to go 3-wire to an amp.
I have MANY horror stories. How about a wrench dropped on the inputs of a trasnformer the size of a coffee table? Wrench simply vaporized with a VERY loud noise. Or the guy who was reaching Uder the base plate of an evaporator and got ZAPPED by the power supply? Or the METER we turned to charcoal whey measuring high voltage......I think it ARCED arounnd the HV probe shield and that was IT.
Lot smore funs stuff.
So In short? I REALLY appreciate your safety bias. Only thing? I have small bits for a DREMEL and may be able to get that hole right. I need to get a cord / relief 'set' so the cord workss with the relief.
Too much is never enough
