There may not be anything wrong with knob & tube wiring, as such. But about 30 years ago, I installed some ceiling fans in my parents' home. My grandfather bought that house in 1943, but it was built in 1922 and had that knob & tube wiring in the attic. And if you touched a wire, all the insulation just crumbled and fell off.Scary, to say the least.
But in reality the insulation never needed to be there in the first place. Insulation doesn't keep the electricity in it keeps everything else out. In walls with proper & complete seperation there's no hazard. I know insulation is added just in case seperation fails.
Different subject but what I find really scary is when the interior insulation disintergrates in newer multi conductor wire. My workplace replaced miles of SE cord a couple years ago from temp wiring & pendant lights where the jacket looked great but inner insulation would crumble if the cord was flexed. MikeD74t
