To close for me. My toes curled just watching!

he stopped to video it? I've been near two high power things that started to glow and killed the power before stopping to panic.

Had a boss on one harass me for not evaluating things in detail first. The electricians said I prevented more expensive damage.

Was doing work in a mobile home, many years ago, and noticed the lights go brighter, when the microwave or the furnace started. Sure sign of a floating ground. As it was, it was night, and I was able to see the glow on the connection box, through the kitchen window. Probably why they had had 2 TVs blow out. I called the power company, and warned him to be careful exiting the home – that the trailer's aluminum exterior was no-doubt 'hot.'

I also knew a pool maintenance worker who was killed, when he got welded to the cement in his bare feet. Who wanted to see why the 3-phase pump motor kept kicking the breaker. Last time I'd seen him, I was trying to dissuade him from indiscriminately poking around in the High Voltage section, of a microwave in the club house. He claimed he had an electrical engineering degree, from Penn State. Don't know about anyone else, but I've noticed a severe lag, in understanding the real-world hazards of electricity, in more than one electrical engineer.
