[QUOTE="chrisc, post: 923780, member: 746"] Some of the sparks you see can be static electricity generated by your body. This is just as lethal to equipment as a voltage differential between the devices you are plugging in to one another. I have seen a spark jump from an external power supply to the device I was attaching, even though both were off. In this instance, the device (a programmable logic controller for a wine chiller array) would not start, so I left it for 30 mins and it came back to life when I pressed the power button then. It was a R30000 piece of equipment and I had spent days sorting out the program at home and here I was at a wine farm with the computer at home 80km away [/QUOTE]
