Yes, I have run a lot of #2 wire. As long as the copper % is there I will chop it.
When I made this video I only had one nelmor granulator.



You can never have enough wire.
It depends on how you load your product. You can't toss a Gaylord of wire in a granulator at one time. The door is too small and the machine will jam. You can chunk 2 or 3 Gaylord's in a shredder at one time. Or you can hand feed 1 lbs at a time. I have tried them all. I like the fastest way
