Conductor insulation damage


St paul, Mn, US
When I was still fairly new in this trade I didn't have too much trouble with stripping NM cable, then was a time we were running a lot of UF cable in ag buildings. I skinned a lot of conductors on those projects at that time. Over time I got better and now hardly ever skin conductors if stripping UF cable. And I don't seem to run into UF cable all that much lately but still haven't forgotten how to do it I guess.
I hate UF really a lot.
