Yes, but not aquarium related. Work related. It’s not fun, I was lucky only had heart rhythm issues, was extremely sore, and my elbows and knees turned black and blue. Someone hired an “electrician” to repair a piece of industrial equipment that wasn’t working. Well, they got it working by stealing the ground conductor and used it as line voltage as one of the line conductors had burned up underground in a conduit. I went to service the equipment later not knowing the history. The motor had frozen and welded but did not trip he breaker. The entire machine was live at 277 volts, when I kneeled down to look at it, I rested my hand on the machine to lower myself to the ground. Well, I turned into a human wiggy. Luckily a janitor saw me and knocked me off the machine with his broom.
