I want to put two 4" square exposed work (metal) electrical boxes next
to each other. They will not be against each other because the
faceplate won't allow that. Other than that small gap, they will be
next to each other. My question is that I want wiring between the two.
Do I just remove knockouts between them and use that way or do I have
to out them far enough apart to use conduit fittings? Or can I get a
gromet for this?
