Larrypride thanks for compliment.
Arc Flash is very serious. We were doing major repairs after a severe storm. After complete rebuild of this one primary cross-arm (3 phase, 14,400 volts), we called the Foreman over for the hot switching. By chance I was selected as the groundman. They switched on A & B phase no problem. When they threw the cutout for C, HUGE explosion (fireball size of car). The hot stick shot up and out of Foremans hand into fireball expanding and covering the bucket. The cross-arm equipment exploded (think ceramic shrapnel). I'm trying to crawl under F-250. I watched the fireball travel up the pole then bouncing between overhead line westward for half mile. This tripped out the 115 kva substation. Thanks to training, PPE and bit of luck no injuries. Flame retardant clothes, safety glasses,hard hats, etc. The Foreman and other Journeyman had managed to drop into bucket before fireball covered it.
