Underground feeder cable (UF cable) is a type of electrical cable designed for underground installation. It is typically used to supply power to outdoor lighting, garden equipment, and other electrical devices. UF cable is durable and moisture-resistant, making it suitable for direct burial in the ground without additional conduit. This cable consists of multiple insulated conductors, usually made of copper or aluminum, surrounded by a protective outer jacket. The design helps prevent damage from soil, water, and other environmental factors. UF cable is available in various sizes and ratings to accommodate different electrical loads and applications.
