Hello again from the dungeon...
As I start to get into building line-driven power supplies and such, where should I start REALLY being careful? 40V? 60V? 110V? I realize that current is what does the damage, but you don't have it without voltage. (I also realize that other factors will factor).
What is the realistic neighborhood of where I shouldn't be grabbing wires and/or switching out caps or resistors in a live circuit?
The physics and shop teacher in HS talked about 110 AC Line current like it would knock you dead instantly. An electrician that was installing a 208v-->480v step up transformer said "110 won't hurt you at all. It's just enough to scare you a little bit".
I'm not about to strip a power cord and bite down on it, obviously, but he's not the first to say 'I've been bit by 110 a bunch of times. It's no big deal'..
Thoughts?
