(a) junction boxes with an interior volume of 1640 Ml^↑ or less that are intended to provide access to wiring and to enclose splices and taps but not to support wiring devices;

(b) conduit boxes with an interior volume of 1640 mL^↑ or less that are intended to be used as pull boxes but not to enclose splices and taps or support wiring devices;

(c) surface mounted device boxes with an interior volume of 1640 mL^↑ or less that are intended primarily to support wiring devices but may also be used as a pull box or to enclose wiring joints;

(d) box covers of the blank and device types;

(e) expansion joints that are intended to compensate for the linear expansion of a span of rigid PVC conduit;

(f) junction box terminal adapters that are intended to connect a length of PVC conduit by an elbow or other bend to a box;

(g) female adapters that are intended to connect a length of PVC conduit to a length of rigid metal conduit;

(h) reducers that are intended to connect lengths of two different sizes of rigid PVC conduit;

(i) caps that are intended to close the ends of unused lengths of rigid PVC conduit; and

(j) bell ends that are intended to provide a bushed opening at the open end of a length of rigid PVC conduit.
