UF-B underground feeder cable is electrical wire that can be buried directly in the ground, with or without conduit. It is typically used as a feeder or branch circuit cable to extend electrical service underground from a main building to a secondary facility. It has a durable nylon jacket that resists abrasion, moisture, and corrosion. UF-B is commonly used in residential and agricultural settings to supply electricity to pumps, garages, sheds, barns, and other outbuildings. It can also be used in wet indoor settings because it resists moisture and fungus.
