12. Flush-mounted installations section 314.20

Installations within or behind a surface of concrete, tile, gypsum, plaster, or other noncombustible material, including boxes employing a flush type cover or faceplate, shall be made so that the front edge of the box, plaster ring, extension ring, or listed extender will not be set back of the finished surface more than 6 mm (1∕4 in.). Installations within a surface of wood or other combustible surface material, boxes, plaster rings, extension rings, or listed extenders shall extend to the finished surface or project therefrom. The installation of common non-metallic 4” round ceiling boxes with the mounting nails on the side must meet the ¼’ maximum setback and be properly secured to the framing member. Nailing these boxes on the very edge of the joist may not meet the minimum setback and could result in the splitting of the lumber, compromising the attachment of the box to the joist.
