This pales in comparison to my conversation the other day with one of our city's elec inspectors. He wasn't asking for it, but we talked about how many of the local guys want all the insulators removed after we rewire and gut out K+T jobs. I of course said it isn't in any NEC code book made to require that, and there is no amendment to the Honolulu code requiring anything like that. Then he goes on to say how he does require that the conductors all be removed, to which I replied that horse hockey to that as well, the code does not require that the old disconnected unused knob and tube conductors be removed, but I always do it anyway cause it gets me around 50 to a hundred bucks in scrap wire every old house rewire job and old macsqueaky , er I mean old macmikey like's to scap wire. But no, he keeps on claiming it is required to remove all unused chapter 3 wiring, and of course I keep telling him it is absolutely not required to do so. Even as he drove away we were in friendly disagreement about it. But removing the insulator knobs- total malarky and I refuse to even discuss it.
