I have recently started stripping wire. I mostly get the wire from dumpster diving. I have this happen a few times, and want to know if it is still considered illegal. I will be stripping the wire,and there will be sections that are black as if burnt. I would say 85% is still bare,and bright. Should i cut the black sections off,and just throw them away,or can i still sell it along with the rest? Thank you in advance
