Which type of conduit is commonly used for underground applications?

PVC conduit is commonly used for underground applications due to its excellent resistance to corrosion, moisture, and chemicals, which are vital considerations for installations buried below ground. Its lightweight nature makes it easier to handle and install, while its insulating properties help safeguard electrical wiring from electrical leakage and physical damage.

Unlike metal conduits, which can corrode over time when exposed to moisture, or aluminum conduit, which may not be as durable in certain soil conditions, PVC stands out as a reliable choice for underground settings. Flexible conduit can offer adaptability in specific above-ground situations but is generally not suited for direct burial applications. PVC conduit’s durability and resistance to environmental factors make it the preferred material for safeguarding electrical installations underground, ensuring they remain functional and safe over time.
