Is 6-3 NM-B allowed in a 2 gang plastic Carlon nail on box? I have seen alot of this in new construction residential range outlet installations. Don't know offhand what the cu/in capacity of the box is, but it just seems wrong. I was "trained" to use a metal "range box" or a 4s deep w/2gang mud ring, and back it up w/some lumber to prevent the box from pushing in when trimming out.
