I first saw this video a few months ago. I was reminded of it by my recent project to install new light fixtures in our bathroom.
I didn’t turn off the breaker because: a) I’ve shocked myself many times before, and while it’s not pleasant, it’s not fatal either, b) the circuit that controls the bathroom also includes the other upstairs room lights, and I was using some of them, and c) just turning off the wall switch accomplishes the same thing. Well, I almost paid for that hubris. I walked to the next room to get something, and when re-entering the (dark) bathroom, I naturally reached for the light switch. I stopped just in the nick of time – had I hit it, the way the wires were just then would have resulted in a short, with the associated spark, flash, smoke, etc. So I wouldn’t have been hurt, but Cindy would have had the “I told you so” rights for weeks.
So the moral is, when you know there’s a right way to do something, do it that way. It’s the right way for a reason.
The video is from an IMAX film and I find it amazing content and wonderful to look at. You may think it’s too sciency, but invest the 3 minutes to hear the final drole comment.
