Finagled my way into the attic to explore a bit. Found this wiring run that basically lays on the sheet rock with insulation sitting on top. It goes to a light switch that controls three of this thin led recessed lights. Could this get really hot and start a fire with the insulation on top?
edit: breathing easier now. Sounds like this is normal stuff. Thanks for the help!
lol I made it half way through your comment and went "That doesn't look like knob and tube! It looks like Romex!" and then literally the next sentence said the same thing.
Ha, realizing the oddity of my phrasing in hindsight. My guess was OP had some smidge of a memory hearing that insulating over wire was bad, so thought it would be worth a little context.
