Which type of conduit is known as Rigid Polyvinyl Chloride Conduit?

Rigid Polyvinyl Chloride Conduit is specifically identified as Type PVC. PVC conduit is widely used in electrical applications due to its resistance to corrosion, lightweight nature, and ease of installation. It is ideal for environments that may be subject to moisture as it does not rust or corrode, making it a popular choice for both residential and commercial wiring installations.

In contrast to the other conduits listed: EMT (Electrical Metal Tubing) is made from metal and is more suitable for indoor installations, especially in dry environments; HDPE (High-Density Polyethylene) is used more for underground applications and is not classified as rigid; and LFNC (Liquidtight Flexible Nonmetallic Conduit) is a flexible conduit that is used for applications requiring flexibility, which does not classify as rigid. This differentiation highlights why Type PVC, as the correct answer, is recognized for its rigid structure and specific material composition.
