About PVC Conduit
Plastic Conduit Systems:
PVC conduit electrical products are widely used for a multitude of applications, including power, telephone, utility and non-pressurized fiber-optic projects.
PVC electrical fittings, including elbows (sweeps) and couplings meeting UL651 are available.
Uses & Applications
PVC conduit and duct is proven durable and effective for years of maintenance-free performance in underground, encased and exposed applications in accordance with the National Electrical Code.
- Commercial, Industrial and Utility Usage
- Corrosion Resistant
- Non-Magnetic and Non-Galvanic
- Impact Resistant
Unlike metallic piping, PVC Conduit is typically not affected by corrosive soils or salts.
Non-Magnetic and Non-Galvanic
Properties of PVC Conduit provide good insulation and no power loss or conductor heating.
Properties make PVC fire resistant.
Tough and durable, yet easy to handle and install right on the jobsite.
Schedule 40 & 80 rigid PVC conduit systems are sunlight resistant and are used exposed, concealed in walls, encased in concrete, and in direct burial applications including systems for:
- Cable, data and communication lines
- Institutional, commercial, industrial buildings
- Residential applications, & service entrances
- Street and highway underground feeds
- Transportation systems – subways, bridges, tunnels, airports
- Water and wastewater treatment plants
- Mines and mills
Type DB-60, DB-100, and DB-120 utility duct are designed for direct burial applications.
Type EB-20 and EB-35 are designed for burial encased in concrete.
Code and Standard Compliance
Schedule 40 and Schedule 80 rigid conduits are third-party certified to UL 651 and are allowed for use with 90º C conductors, in accordance with the National Electrical Code. They are manufactured in accordance with NEMA TC2.
Type DB and EB ducts are manufactured in accordance with ASTM F512 and NEMA TC 6&8 are allowed for use with 90º C conductors.
PVC fittings are manufactured in accordance with NEMA TC3. The UL standard for PVC fittings is UL 651; for boxes UL 514C, for cover plates UL 514D and for enclosures UL 50.
