Underground feeder (UF) cable is used to distribute power from buildings to outdoor fixtures like buildings, pumps, lighting, and equipment. This wire can also be used for irrigation applications and as a locating wire for underground utilities and other assets.
Single conductors are solid or stranded and annealed or hardened uncoated copper.
Conductors are insulated with a concentrically applied PVC (polyvinyl chloride).
Print legends on the wire include the manufacturer, conductor size, voltage rating, UL symbol (if applicable) and type designation. Standard length spools are 500 or 2500 feet.
