Hi I was wondering if you can buy insulated copper wire from a scrap yard ? Like say big stuff that I wouldn't normally see like 500mcm. I just was wondering if they would do it or not? If it's a waste to even ask???. It would be cool if I could then I could get to run 500mcm or 250 mcm in my stripper haha. I ran plenty of Romex and then and 4/0 is the highest I have ran same with ec wire.
