I honestly don’t see a reason why it would hurt if there’s nothing wired to the breaker. And it feels safer than leaving the contacts exposed since the metal cover is open on those slots. But I’m not sure if that’s the proper way.

As for the wire, I think it’s more so quality control. If it’s new and you bought it then you know it’s high quality and if it doesn’t work you can warranty your own work, but you can’t warranty old equipment. But this is another one where I can’t see the harm in using it if I am replacing a short strand of wire and it is the right length. Like I said, it’s type NM cable so it seems to be equivalent to modern romex wire, just a different brand.

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.

Ya, there is asbestos in the house. It is wrapped around the HVAC in the basement. We were told to get it removed now because it’s not yet a health hazard so I’m working on getting that done. It’s still in good condition and it’s not dangerous until it starts to flake away. But the insulation is newer from a remodel when the last owner turned it into a duplex. So within the last 10 years I am pretty sure

12/2 is what I bought for the basement lights I’m working on. Everything I read said that was the appropriate wire to use so I never even co sidered #14

I knew it had glass in it but I wasn’t sure if that’s all it was made of. That and the paper backing just made me want to be cautious. But I do know how to handle insulation from tearing a room off my grandparents house a few years ago.

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

I’ve been through 6 electricians and 3 general contractors. Probably more but I can’t keep those numbers straight. They all show up to give a quote then never actually do the work. I’m tired of it.

That being said, the insulation just feels flammable to me. It’s clearly marked otherwise but the paper backing and stuff just made me want to double check

Tried this at work the other day. Apparently this doesn’t work in call centers… anyone hiring?
