Construction:

Conductor:Solid soft drawn bare copper per ASTM B3 or class B compressed stranded soft drawn bare copper per ASTM B8
Insulation:All phases and neutral are insulated with Polyvinyl Chloride (PVC) with Nylon Sheath
Ground:Solid soft drawn bare copper
Jacket:Gray Polyvinyl Chloride (PVC) jacket. Sunlight, moisture and fungus resistant.

Applications and Features:

Southwire® copper UF-B cable is generally used as a feeder to outside post lamps, pumps, and other loads or apparatuses fed from a distribution point in an existing building as specified in the 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°C (with ampacity limited to that for 60°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.
