I thought the Subject was Metal boxes ?? When did we get off on lugs to steel ect.If you feel a cable clamp screw well do the Job by all means Go for it BUT like I said try it some time you:ll see what I mean. As Far as the NEC Code handbook I feel its interpretations as as good as any you:ll find.Several of people who had a hand in the handbook are on the code panels. No hard feelings been fun sparing with you time to move on.
