Southwire copper UF-B cable is generally used as feeder to outside post lamps, pumps, and other loads or apparatus fed from a distribution point in an existing building as specified in the 2011 National Electrical Code. UF-B cable may be used underground, including direct burial. Multiple conductor UF-B cable may be used for interior branch circuit wiring in residential or agricultural buildings at conductor temperatures not to exceed 90 degrees C (with ampacity limited to that for 60 degrees C conductors) as specified by the National Electrical Code. UF-B can be used in applications permitted for NMC in Section 334.10(B) of the National Electrical Code. Voltage rating for UF-B cable is 600 volts. Southwire copper UF-B cable is manufactured as a 2 or 3 conductor cable, with or without a ground wire. Copper conductors are annealed (soft) copper, solid or compressed stranded. Phase conductors are polyvinyl chloride (PVC) insulated, nylon jacketed, color coded for identification purposes. Jacketed with sunlight, moisture and fungus resistant gray PVC.
