Which installation is buried directly in the ground?

Which installation is buried directly in the ground?

• A. Indoors
• B. Aerial
• C. Buried directly in the ground
• D. Installed underground in conduit

Answer: (C)

Direct burial refers to placing cable straight into the soil without any protective conduit. The cable itself is rated to withstand moisture and soil conditions, so it can be buried directly in the ground at the required depth and with proper soil bedding and warning measures. This is different from indoors, which stays inside structures; or aerial, which runs above ground on poles; or underground in conduit, where the cable is buried but protected inside a pipe or duct rather than being buried directly in the soil. The correct choice describes exactly a direct-burial installation—the conductors are exposed to the earth rather than contained in conduit or kept indoors or above ground.
