Which type of conduit is typically used for outdoor applications?

Rigid PVC conduit is commonly chosen for outdoor applications due to its durability and resistance to environmental elements. This type of conduit is non-metallic, which makes it resistant to corrosion, a significant advantage when exposed to moisture, rain, or soil conditions. Furthermore, rigid PVC can withstand UV radiation, meaning it can be used effectively outdoors without deteriorating over time due to sun exposure.

Its structural integrity provides excellent protection for electrical wiring against physical damage, making it a reliable choice for safeguarding electrical systems in residential and commercial installations outside buildings. Rigid PVC conduit is also lightweight and easy to install, contributing to its growing preference in various outdoor electrical projects.

In contrast, the other types of conduits may not offer the same level of protection or suitability for outdoor environments. Flexible PVC and soft plastic conduits can be less durable when subjected to harsh weather conditions, while metal conduit, although strong and reliable, can be prone to corrosion if not properly coated or galvanized, especially in moist outdoor settings.
