What is the difference between copper #1 and #2. When bringing in my copper today I had a ball of copper got from some wires., they were kinda thick.. the young Guy at the scrap yard said it was #1 but when weighing my copper it was all together as #2. I'm assuming #2 is thin copper wires out of TVs and such.. also had a bag of insulated wires (.60) they ask what kinda wires were in it? Anyway just wondering the differences
