Which type of conduit is typically used in wet locations?

PVC Conduit is specifically designed for use in wet locations due to its inherent properties that resist moisture and corrosion. Unlike metal conduits, PVC does not conduct electricity, making it safer in environments where water exposure is a concern. Additionally, PVC is lightweight, easy to install, and can handle the effects of various environmental conditions without deteriorating, which is essential for ensuring the longevity and reliability of electrical systems in wet locations.

Moreover, PVC conduit's resistance to various chemicals and its robustness against the elements make it an ideal choice for installations that require protection from water ingress. This versatility allows for wide application in areas such as underground installations, outdoor on-building exteriors, and areas subject to frequent wet conditions.

In contrast, the other types of conduits mentioned are generally not recommended for wet locations due to their material properties and potential for corrosion or electrical hazards when exposed to moisture.
