While we're on this subject, it seems as if the wire insulation is getting flakier as well. I did a job recently where the customer supplied his own THHN that I think he bought from a big box store. It was #12 solid. When we were done, we ended up having two shorts. In both instances, the insulation had taken the slightest little nick and gave out. I sure remember it being a lot more durable, largely due to the thicker nylon outer covering. It seems like that is almost non-existent now.
I don't even want to talk about how flimsy the jacket has become on Romex cable.
