Does NEC specifically prohibit NM cable in an old K&T switch box?
I need to do the calculations, but I think I have room as I'm just terminating a 12/2 cable to a receptacle (K&T removed from box).
My question relates more to the clamps. The old clamps are designed for the circular profile of the K&T insulation. Not sure if this will cause cable damage or cause other problems with cable. Also, since it is K&T - no grounding screw present. My plan was to use a grounding screw on the existing unused threaded hole for a second set of internal clamps
Thanks in advance.
