What must be done if a conduit is not rated for direct burial?

When a conduit is not rated for direct burial, it is essential that it be installed above ground or protected with proper enclosures. This is because conduits that are not specifically designed to withstand the conditions of being buried underground may not provide adequate protection against moisture, soil pressure, and potential physical damage. Above-ground installation helps ensure the longevity and integrity of the conduit, preventing issues such as corrosion or electrical failures.

Using proper enclosures when the conduit must remain in the ground provides an additional layer of protection, allowing the installation to comply with electrical codes and safety standards. Ensuring that the conduit is either raised above ground or appropriately shielded informs best practices in electrical installations, safeguarding both the equipment and the safety of individuals in the area.
