I actually like this guy. He is close to me in terms of his work.
But.....watch the end of his video and tell me if the beer has affected his judgement or is it ok to mess around with 110 ac without a care in the world?
I grew up in Canada in the 60's/70's. My dad (a welder) was practical, but you couldn't accuse him of wrapping me in cotton wool. This was the man who made me a sword out of scrap metal for my pirate costume and sent me off to the Cubs Halloween party with it. It was swiftly removed by Akela.
Anyway, he also let me play in his workshop as long as I never ever touched his table saw. This was in our basement, so the floor and walls were concrete. The socket for the light (no wall switch) was for some reason about head height on the far away wall. I remember stumbling my way through in the dark, finding the two pin plug for the light; holding it in my right hand and with my index finger between the two prongs and feeling about for the socket and with the tip of the same index finger. More than once I plugged in the light with my finger still between the prongs. Sometimes a tickle, sometimes a jolt. Always fun
Edit: I just remembered: I made a big electromagnet out of a copper wire and a plug. That thing heated up and buzzed a lot. Also blew fuses.
I got 380 volts across the chest in a school when some fool had stolen a live from a different board on another phase, the board I was working on was turned off, I'd been stripping out a couple of circuits when I lent me left hand on the metal trunking and my right hand touched the neutral bar. BOOM!
That hurt!
I eventually found that an emergency light was wired with the live from the kitchen board and the neutral from the one I was working in so when I isolated the board it left a floating neurtal. After I turned the double pole isolator off I checked between live and neutral and live and earth and it was dead, after the belt I checked between neutral and earth and found 380 volts!
