Yup, I sold a guy a system to control some servo motors in a CNC application. It had 4 servo amplifiers with big power FETs on a mounting plate, with Bergquist insulating thermal pads. He had a guy assemble it all into a box, and this guy drilled big holes and put giant screws into the mounting plate that shorted out the transistors. This was running off a 120 V DC supply. Lots of fireworks!
