Southwire Type UF-B copper cable feeds outdoor and underground branch circuits and may be buried directly in the earth. 2 solid 12 AWG copper conductors and a full-size solid copper ground are individually insulated and sealed in a gray PVC jacket rated 600 volts, supplied here as a 50 ft coil.

• Type UF-B, 12 AWG solid copper, 2-conductor with ground
• Conductor colors black and white, plus a 12 AWG solid copper ground
• 600 volt rating
• May be used underground, including direct burial
• Gray PVC outer jacket
• Southwire lists UF-B as a feeder to outside post lamps, pumps, and other loads fed from a distribution point in an existing building
• Multiple-conductor UF-B may also be used for interior branch circuit wiring in residential or agricultural buildings
• May be used in applications permitted for NMC under National Electrical Code Section 334.10(B)
• Conductor temperature not to exceed 90 deg C, with ampacity limited to that for 60 deg C conductors
• Approximate cable weight 96 lb per 1000 ft
• Supplied as a 50 ft coil

Tip: Burial depth and ampacity for UF-B are set by the National Electrical Code and by your local inspector - confirm what your circuit requires before you dig. Southwire publishes this cable to a 90 deg C conductor temperature with ampacity limited to that for 60 deg C conductors, so size the breaker to the 60 deg C column.
