I happen to have a lot of first hand experience with power lines.
I have knocked several down.
I have "turtle-ized" down inside the bucket (Tree company bucket truck) when someone else made the hot line and the neutral lines touch- which sends a BIG FREAKIN BALL of lightning down the lines to "blow off" whatever is causing the short...
You wanna talk about SHEETING your pants!!??
I have also been "hit" by 7,200 volts of primary, in one hand, down the arm, across the shoulders, up the other arm, out the other hand....
Let me inform you all right here, right now: You do not want to try this yourself. I sat in the doctor's office for 3 hours hooked to a heart monitor.
Turns out that a shock like that can stop your heart......up to 3 DAYS after the fact...
It also turns out that an electrical burn isn't "you get a burn and that's it"...
No....electrical burns CONTINUE to burn for DAYS after the hit....they actually GET WORSE OVER TIME......FROM THE INSIDE OUT!!
This is all 100% true, as driven into my head by Central Maine Power Company's safety supervisors....and real world experience..My shoulders hurt like hell for 4 days...it was the burn INSIDE the muscles..I got super lucky....whilst being super absent minded around power lines.
Be careful...no line is safe to touch, none. DO NOT touch poles, or guy wires.
They can be "hot" if a branch is touching the hot line and the neutral 2 miles away...
