I was working at a power plant in East Texas when it came time to pack up the work trailer. About 8 ft up on the side of the trailer was an access door about 18" square. Through this door went the 440 volt ac feed and the phone wire.
I would disconnect the phone lead and after we left, the plant electrician would disconnect the 440 volt line. It was well insulated but on an aluminum ladder, against an aluminum trailer with an earth ground, I would reach in gingerly the pull the phone line. Really not a biggy since phones are low voltage. Well, in East Texas the phones were using 110 volt dc. I thought I was a dead man.
