OK, I'm confused. The YouTube link I saw had nothing to do with light poles. It was a scene from This Old House, where their house electrician showed how he steals power for temporaries.
I'm not going to lie and say that I've never done this, but certainly not in such a brazen manner. Fiberglass ladder or whatever, that fool did everything against common sense.
First, I'd have made the neutral the last conductor that I cut.
Second, I certainly would not have stripped the end of a hot leg until I was ready to terminate it.
Third, I wouldn't let some onlooker on an aluminum ladder be anywhere close to what I was doing.
Fourth, I'd have had safety glasses and gloves on at a minimum.
Lastly, I sure wouldn't be advertise that I'm stealing power on national TV, even if only for a few hours. I know that POCOs around the country have differing policies about this, but if we do that here, we can get charged with utility theft. If we need temporary power, then we have to set a temporary service and have them feed it for us, period.
