Some very cool videos from lineman showing high voltage air switches opening under even a reduced load.
I think most folks don't understand electric components don't like being manipulated under a load.

I was taught the procedure of disconnecting a 10/20kV disconnect for an on-site transformer (alas, only an old one that had been decommissioned) and that thing scared the crap out of me when I first heard the spring loaded high voltage disconnect actuate.
Having a 3 meter fibreglass pole to actuate the thing, just incase, tells you there is a real risk of the thing blow up in your face, on a good day.
