Hi,I'm a rookie poster to this site and have a query.I Was just on a DIY site and a poster asked where he could get a 250' run of USE for a project he was working on.Am I mistaken in beliving that any type of wiring removed from one installation cannot be permanently installed in another location.This person was interested if a scrap or salvage yard would sell him the length he needs.Is this in violation of art.300 ?
