The distance a metallic plug or plate should be from the outer surface of a nonmetallic enclosure defines which term?

Explanation:
The distance from the outer surface of a nonmetallic enclosure to the face of the metal plug or plate describes a recessed plug or plate. This term specifically refers to how far back the device sits inside the enclosure, not protruding or flush with the surface. It’s about mounting depth, whereas the other terms relate to how conductors are connected (pressure/ set-screw connectors) or how conductors are identified (labeling). So the correct term for describing that distance is recessed plug or plate.
