Application & Features

Southwire® UF-B Copper Cable with Qwik Strip™ Jacket is engineered for clean cuts, fast installs, and fewer mistakes. Precision-engineered grooves along the outer jacket serve as visual and physical cut guides, enabling accurate terminations with greater consistency and efficiency—no specialty tools required, and with reduced risk of conductor damage or installer injury compared to standard UF-B. This cable is ideal for use as a feeder to outdoor post lamps, pumps, and other loads or apparatuses fed from a distribution point in an existing building, as specified in the National Electrical Code® (NEC). It is approved for underground use, including direct burial, and may also be used for interior branch circuit wiring in residential or agricultural buildings at conductor temperatures not exceeding 90°C (with ampacity limited to that for 60°C conductors), per NEC guidelines. UF-B is also permitted in applications outlined for NMC in NEC Section 334.10(B). Voltage rating: 600 volts.

Ampacities based upon 2023 NEC Table 310.16 and do not take into account the overcurrent protection limitations in NEC 240.4(D) of 15 Amps for 14 AWG CU, 20 Amps for 12 AWG CU, and 30 Amps for 10 AWG CU (independent of the conductor temperature rating and stranding if size is present in table). Also, see NEC sections 310.15 and 110.14(C) for additional requirements.
