I believe my house was built in the early '70's when aluminum wiring was acceptable. I suppose one of the first occupants added some more fixtures and used copper instead so now there's a mix of aluminum and copper throughout.
I want to add some LED pot lights to the basement area and the easiest way to do this is to run from an existing nearby box. This box is fed with aluminum wiring. Can I safely continue from there with copper to my pot lights?
