I have always kept old wire to bring to the scrap yard. I only use 3 categories - Aluminum - dirty copper - bright copper. I don't go into any further sorting. I've always thrown light fixtures and fans away. I was thinking today that I should probably craigslist this stuff. This got me thinking about the 400+ circuit breakers in my shop that have an inch of dust on them and all of the panels and misc pipe etc. that I throw away. Does anyone get more involved in scrapping or reselling? I'm just curious how much "easy" money I might be throwing away.
