Description / Abstract:
This Standard specifies the requirements for low-halogen
aboveground (Type AG) reinforced thermosetting resin conduit (RTRC)
and fittings for installation and use in accordance with CSA C22.1,
Canadian Electrical Code (CEC), Part I, and NFPA 70, National
Electrical Code (NEC), in non-hazardous locations.
The products specified in this Standard are intended for use at
-40°C (-40°F) to 110 °C (230°F). The products are for use above
ground in exposed and concealed locations. The products are also
suitable for use below ground by direct burial or by encasement in
concrete.
Type AG conduit has not been evaluated for directional boring
applications.
This Standard covers ID (dimensions based on inside diameters)
and IPS (dimensions based on outside diameters of iron pipe sizes)
conduit and fittings. Trade sizes (metric designators) are 1/2 (16)
to 6 (155).
Note: The values in parenthesis are metric size
designations of conduits and fittings and do not necessarily
reflect metric trade sizes.
ID and IPS conduit are designated as SW (Standard Wall) or HW
(Heavy Wall), which refer to specific wall thicknesses.
Fittings specified in this Standard include, but are not limited
to, straight couplings, 5° angle couplings, adapters, and elbows
with plain ends or integral belled ends at one or both ends,
expansion joints, and conduit bodies.
Note: In Canada, conduit bodies are not evaluated as
outlet boxes – they are fittings. Requirements in this standard for
conduit bodies intended for use as outlet boxes do not apply in
Canada. In the United States, a conduit body may be used as an
outlet box for the splicing of conductors.
