Southwire 12/3 Solid Copper UF-B Underground Feeder Cable with Ground 250-Foot Roll – Model 13058355

The Southwire 13058355 is a 250-foot roll of 12/3 AWG solid copper Type UF-B underground feeder cable with an integrated grounding conductor. This cable is engineered for direct burial applications and outdoor branch circuit installations where moisture resistance and durability are required.

The 12/3 configuration includes three insulated 12 AWG solid copper conductors along with a bare copper grounding conductor. This setup is commonly used for multi-wire branch circuits, outdoor equipment, detached structures, and installations requiring two hot conductors and a neutral.

UF-B cable features a rugged PVC insulation and jacket system designed to resist moisture, sunlight exposure, and soil contact. Unlike NM-B cable, UF-B is approved for direct burial without conduit where permitted by local code.

Rated for 600 volts with conductors suitable for 90°C, this cable is designed to meet National Electrical Code requirements for underground and wet-location installations.
