You spin some around with a tip tie, you slide some off (that won't catch) the primaries and deflect or bounce some off too. you use all the tricks but you have to build up experience to do the real hard ones or you will tear wires down, blow a transformer or likely get killed.
Electrocution kills more climbers than any other accident.
this is in no way giving advice to a green climber to give it a try. This isn't like learning the distal or how to use srt etc.
I'm way to old and stiff to do this. I just want to learn what some of the tricks are because I'm curious.
