Scope
1.1
This Standard applies to rigid un-plasticized poly (vinyl chloride) boxes and fittings of the following types that are intended to be installed and used with rigid PVC conduit at a maximum working temperature of 75°C in accordance with the rules of the Canadian Electrical Code, Part I:
(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.
For convenience, the shorter term PVC is used in this Standard. ×1640 mL is the volume of trade size known as 100 cubic inches.
