Got shocked by 120VAC

One important TIP for young players!....
It's NOT uncommon to either leave or find possibly live old wires, in many scenarios.
It seems obviously BAD to just cut a wire off!!, even if the Copper is not apparently visible... That's a given!...
However, what's WORSE, is when someone THINKS they are making it safe, by putting a Blue-Point Connector on the end, like...

BUT putting it OVER the plastic of the wire!!  People may TEST the screw-head inside the connector, and think it is dead!!   :palm:
If you do this, ALWAYS strip the insulation back, and screw the termination onto the copper!!   :-+

I do this regulary,..
After confirming it with multimeter that there is no lethal voltage present, i quickly touch with the back of my right hand, whil keeping the left one on my back. I can say that after multimeter measurment i am 99% sure and after hand check i am 100%

When I was going through electrician's license education program, I was told time and time again, if you didn't turn the circuit breaker off yourself and measured it yourself, assume every line LIVE.  I still follow this.

Risk from 120V  in DRY ENVIRONMENT  is not really the electricity itself.  You could yank your hand off and hit something else.  You could fall off a rafter.  You could fall off ladders.  You could fling tools and hurt someone else. 

Common practice is to put a wire nut on unused but live wire.  It was unprofessional of someone who did that years ago.

He was trying to measure his internal resistance, but I guess what he ended up testing was the internal resistance of a 9-volt battery!

Then wrap it with multiple layers of insulation tape.

By the way, the latter gets a "bad rap".
We tested two layers of "El Cheapo" tape with a Trimax Ionisation Tester, & it held out till around 10kV.
It just shows how much overkill we use in normal work.

If you ever see one of those Ionisation Testers up for sale cheap, grab it-- they are loads of fun!
