Not to argue that K&T is good, but a couple decades ago, when my father expressed concern that the K&T wiring would start a fire in his house, I went up and removed from circuit a short sample of a K&T conductor. I brought it to him and bent it in the middle, folding it back 180 degrees and then straightened it back out. The insulation didn't split or damage in any way. It looked like brand new. I suggested to him that the issue with the wiring had more to do with devices (outlets and switches) that were so old and the lack of grounding than from the quality of the insulation on the conductors themselves. This was long before becoming an inspector but after my education in electrical engineering. Marc Exactly,as long as knob and tube wiring hasnt been hacked/butchered by somebody reading a book at the hardware store thinking their an electrician I generally have no problem with it myself as a contractor.We still have many houses in the older parts of omaha with knob and tube
