I could not watch to the end this guy is really stupid even if he is doing it on purpose. Many many years ago working at Keyport Nuclear Torpedo Base I was tightening down a neutral conductor in a 400 amp 3 phase panel that ran our national defense computers in the same room. They told me no way can this panel be shut off. It was also located a few hundred feet from the hi tension towers outside. Worst yet this special panel was designed for no voltage drop! It was fed with 4- 750MCM cables each one larger then size of a quarter and made of copper. Well I told myself I should use a short shanked screw driver but it was in the truck? I almost got it tight when it slipped out of the screw and slid right into the buss bar! I was told later a flame about 8 ft long came out of the panel seen by a lady watching me from her desk. The hallway filled with smoke and blew the screw driver out of my hand which was in front of my face. I had burn marks all over my face and was blind for about 1 hour and could not hear about the same time from the explosion! Most of my hair was gone including my mustache!! I also blew the main 800,000 AIC breaker(control surges by shutting off fast if not the breaker would have also exploded) to the panel and shut down all the reel to reel computers programing the torpedo's they were building in this room! It blew a hole in the back of the panel and all that melted steel burned holes in my cloths. My eyes were saved because my hands were in front of my face protecting them. That almost made me quit being a electrician and I sure learned what real high amperage can do if you mess up! That is my story and I am sticking to it!!
