There is some serious arc welding going on.

I'd like to have seen some of the aftermath.

Arc flash...that's why I don't play with anything hotter than 240:

I am deathly afraid of power lines...this one is gruesome.

My FIL worked for the local power company. One Sunday while I was visiting he got an emergency call from a local ammonia manufacturing plant. He asked if I wanted to tag along so I did. One leg of a 3 phase substation was off line. I have no idea how much power the place uses but it was MAJOR. There were three separate substations side by side all feeding just the one plant.

I tagged along and stayed in a metal & concrete building in the middle of the substation. A fuse had blown and it scattered parts of it for hundreds of feet. The guy he was working with was another long term very experience man. They did not say more than a few words to each other. They each knew what to do step by step. They would both stop and one would call headquarters and say something. A minute later just a grunt was enough to let the other know it was on to the next step. In a few minutes another call and a few words another grunt and in 20 minutes they threw the switch and the plant was back up and running.

You could feel the electricity humming in the place. It was amazing and a little scary.

I've seen a 440v line bore a hole in a 100 yr old Elm tree. The tree survived...

You think he's OK? http://www.vettemod.com/forum/images...y-shocking.gif

Looks like the conductor came down, found a path to ground (thru the train) and the breaker didn't open......it just saw additional (alot) load.

Somebody needs to look at fuse/breaker coordination.
