A while back, Joe Tedesco quoted a Los Angeles City Code section which states that abandoned wiring should be removed. This is a good example of why. This 600A 480/277 section was smacked hard by a forklift about 30 years ago. Although the branch wiring was removed and rerouted to other sources, the feeder was never removed, and remained connected to the disconnect in the 2000A service. In the meantime, someone had closed the disconnect, and this thing was hot when I got there to do some other work. Nobody knew how long it had been on, but the entire interior was just dangling from the top insulators, and a good quake would have gotten something together, with possible disastrous results....Scott (Electure)
Joe, It's been removed entirely. The customer actually is a very good one. Very concerned about a safe workplace, and just didn't know that this was in their back 40. The "millwrong" still works there, but is under a heck of a lot more scrutiny...S

That ain't good!. It would make you wonder why the feeder wasn't disconnected at the same time as the other circuits were re-routed. Even so, the upstream protection should have been locked out/pulled.
