What type of cable is specifically designed for underground use?

• A. NM (Non-Metallic) cable
• B. Type MC cable
• C. UF (Underground Feeder) cable
• D. Type NM-B cable

Answer: (C)

UF (Underground Feeder) cable is specifically designed for underground use because it is constructed to withstand moisture and is resistant to damage from the environment it is installed in. This type of cable has a rugged outer jacket that provides protection against water and soil exposure, making it suitable for direct burial applications in wet locations. UF cable is often used for underground installations, such as supplying power to outdoor lighting, garages, or other structures where the cable will be buried. In contrast, Non-Metallic (NM) cable and NM-B cable are intended for indoor residential wiring and do not have the moisture and environmental protection necessary for underground applications. Type MC cable, while versatile and used in various applications, is more suited for exposed or concealed installations, such as in commercial buildings, rather than direct burial in earth. This highlights why UF cable is the correct and appropriate choice for underground installation needs.
