hey sparky, yes that is the one. i have seen different methods. i.e., several holes drilled in the header and individual clamps at the box, like the photo portrays and a 2' or a 2-1/4" pvc or emt conduit run from the panel thru the header an the branch cables passing thru. i'm familiar with the 24" nipple rule and max # of cables. are there any other reasons why the conduit thru the header is not nec worthy?
providing the cables are secured prior to entry into the conduit and a sealer is used. thx., ken m
