Which NEC Article is associated with Rigid Polyvinyl Chloride Conduit?

The association of Rigid Polyvinyl Chloride (PVC) conduit with Article 352 of the National Electrical Code (NEC) is grounded in the specifications and standards for installation and usage of rigid non-metallic conduit. Article 352 outlines the requirements for Rigid PVC Conduit, including its applications, installation practices, and performance criteria.

The key focus of Article 352 is to address the properties and permissible uses of rigid PVC conduit in electrical installations. It covers aspects such as the conduit’s resistance to ultraviolet exposure and moisture, as well as its physical characteristics which contribute to its suitability for underground installations, direct burial, and protection in various environments. Understanding these specifications is crucial for ensuring safety and compliance with national standards when using this type of conduit in electrical systems.

The other options relate to different types of conduits or raceways, which do not apply to Rigid PVC. For example, Article 344 pertains to rigid metal conduit and Article 356 covers flexible non-metallic conduit, which are distinctly different in terms of materials and installation requirements.
