I was always told that part of the connector had to be in contact with the cable thus you were limited to two cables.I have never had an inspector insist that they both be 12 or 14.
Interesting! Each jacket in contact with the connector, so a stack of three flat cables is NG, but one flat with two 'on edge' may fly?? Something like |=, as oppesed to ||| ?
clarify: the side of the cable,not the edge. Now we see why the code is updated every three years
