How does PVC conduit differ from metal conduit in applications?

PVC conduit is distinguished by its lightweight nature and strong resistance to corrosion, making it an ideal choice for outdoor applications. This material does not rust or corrode in the presence of moisture, unlike metal conduit, which can be subject to degradation when exposed to the elements. Furthermore, the ease of handling and installation of PVC, due to its lighter weight, often makes it a more appealing option in various installation scenarios.

In contrast to the other options, while PVC may be less expensive than some metal counterparts, it does not corrode easily—a trait that enhances its longevity and performance, especially in environments where moisture exposure is a concern. PVC conduit is, in fact, specifically designed for durability in both outdoor and underground settings, contradicting the notion that it cannot be used for these applications. This highlights the advantages of PVC, particularly for projects that require reliable and cost-effective solutions in various environmental conditions.
