Another war story....
...if you're gonna build something with a BRS, make sure it can be TESTED without causing all hell break loose. If it's not tested, it doesn't work. Guaranteed.
Working around a big, hairy power supply. 40kV @5A is memory serves. Insulation breakdown, arc to ground. Not a happy little arc, a pucker up and make a diamond ... mean ... freakin' bright and scary arc. Overcurrent protection? Crowbar? Nope!! Senior tech, an older gentleman, does a highly athletic vault over workbench - must've cleared it by half a meter - pirouettes, hits BRS. Nothing happens. That's when it got real. Post mortem? BRS was never connected. Never tested, either.
Biting the hand that feeds IT
