Have any of you seen or intalled nm cables into the top of a panel via a 2" or 3" pvc nipple instead of thru separate nm connectors? I've seen this at a couple locations, never did it myself, but I thought I saw something in the NEC addressing this by way of an exception. Either that or I saw it in a book or magazine article. I'm just trying to find out about this for a friend, he said his son's house was wired that way. I'd think there would be issues about securing the cables at least. I figured someone here may know something about this. thanx...
