Type UF cable used with a 24V landscape lighting system can have a minimum cover of how many inches?

Type UF (underground feeder) cable is designed for direct burial in the ground without the need for additional conduit. For a 24V landscape lighting system, the applicable code specifies that UF cable must be buried at a minimum depth to provide protection from physical damage and environmental factors.

The correct minimum cover for Type UF cable in this scenario is 6 inches. This depth ensures that the cable is sufficiently protected when installed underground. Such requirements help prevent accidental damage from surface activities, such as gardening or landscaping, and assist in maintaining the integrity of the electrical system.

Understanding the depth requirements is crucial for adhering to safety standards and ensuring reliable performance of the landscape lighting system. Other options exceeding 6 inches do not align with code requirements for residential applications involving low-voltage installations, which makes 6 inches the appropriate choice for this type of cable used in such systems.
