Evening, I’m normally an industrial electrician so never work in houses, but something I’m wondering about:
If you run a cable through space between ceiling and floorboards, do you de-rate the cable for ambient temperature if there are un-insulated pipes sharing the space? Obviously it’s going to get pretty warm in there!
