The conduit is Schedule-40, Schedule-80, EPEC-A, or EPEC-B High Density Polyethylene (HDPE) in trade sizes 1/2 (16) - 6 (155). This product is intended for installation in accordance with the National Electrical Code, NFPA 70. The values in parentheses are metric trade designators of conduit. The designations Schedule-40, Schedule-80, EPEC-A, and EPEC-B refer to conduit having specific outside diameters and wall thicknesses.This product is for aboveground use where encased in not less than 2 inches (51 mm) of concrete and for underground use by direct burial or encasement in concrete. A product that contains features, characteristics, components, materials, or systems new or different from those covered by the requirements in this standard, and that involves a risk of fire, electric shock, or injury to persons shall be evaluated using the appropriate additional component and end-product requirements to determine that the level of safety as originally anticipated by the intent of this standard is maintained.
