UL Standard for Safety Aboveground Reinforced Thermosetting Resin Conduit (RTRC) and Fittings (First Edition; Reprint with revisions through and including January 24@ 2014)
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??(-40?? to 110 ??(230??. 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??ngle 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 ?C 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.
