What conduit type does Type 352 refer to?

Type 352 specifically refers to Rigid Polyvinyl Chloride Conduit (PVC). This type of conduit is designed for use in outdoor and indoor applications where moisture, chemical exposure, or sun damage could be a concern. It is known for its durability, resistance to corrosion, and ability to handle high levels of electrical protection.

Rigid PVC conduit is particularly popular due to its flexibility in installation, availability, and cost-effectiveness, making it a standout choice in various electrical wiring applications. It can be used in environments where other materials might degrade or corrode over time.

The other options represent different types of conduit with specific applications and attributes, but they do not apply to Type 352 as accurately as Rigid Polyvinyl Chloride Conduit does. For instance, Liquidtight Flexible Nonmetallic Conduit is designed primarily for flexibility and moisture protection rather than rigidity. High Density Polyethylene Conduit is effective in certain specialized applications, while Electrical Nonmetallic Tubing is lighter and less suitable for heavier installations. Thus, understanding the specific characteristics of Rigid PVC helps clarify why this option is the correct choice for Type 352.
