Hello, I’m back with another question. Everything a read is telling me yes I can, but it really does not feel right so I’m gonna ask here for good measure. Can I run electrical wire through fiberglass insulation?
In several rooms upstairs the wire comes out of the center of the ceiling then goes across to the window where a fluorescent tube light is installed. Below all that is a drop ceiling tile with insulation packed on top of it. I want to take the fluorescent light out and put a normal light back in which is easy enough. My concern is running the wiring through the insulation. Everything says running it through insulated walls is fine and the insulation itself says it’s non-combustible. But can someone confirm that I’m reading the right stuff?
There’s a gap between two pieces of insulation that I want to run the wire between. Picture attached. Not sure how old the insulation is if that is important.
Regular modern romex wire is fine.
You can’t insulate over old knob and tube since the cloth insulation degrades and flakes off.
Tell that to the maniac who wired my house 95 years ago.
The guy wiring with knob and tube was probably not the maniac who put insulation over it at a later date.
AFAICT it was all done in a four-year period from 1926 to 1929 and untouched until I ripped the ceiling open in 2018.
This is thankfully not knob and tube. The house is old enough for it though. Going in the attic you can see where the wires used to run
