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.
Make sure you’re buying 14/2 or 12/2 that has a ground wire and running that back to the breaker box. I saw the job you did with the big cable in the floor and it didn’t look like you ran a new cable that had a ground wire. It’s best to replace the old shoddy stuff with circuits that are up to code, even if you’re doing it DIY and your area doesn’t require homeowners to get it inspected. The codes are designed to prevent fires and loss of life.
That was a 240v circuit. It didn’t have a ground because it was 10/3. I had the money to get the stuff with a ground, but they were sold out and I couldn’t get anything for a few weeks so I went with the no ground but it is still up to code and manufacturer approved.
This does have a ground and black is going to the breaker with white and ground going to the ground bar.
