Direct burial wire and cable are types of electrical service wire that can be placed directly in the ground without needing protection from conduit. These products can withstand exposure to soil, moisture, and fungus and are rated for wet, dry, and damp environments. Underground cable is also shielded from outdoor elements, such as tree limbs and storms, lessening the potential for damage and extending the life of the wire. Direct burial wire and cable are typically used to extend electrical service from a distribution point to an outdoor application, such as landscape lighting, solar panels, sprinkler systems, and outbuildings.
