Southwire 13058355 Uf-b Underground Feeder Wire 12 Awg 250 Ft

Product Description

The SOUTHWIRE 13058355 is a Type UF-B underground feeder cable rated for direct earth burial and suitable for use in branch circuit wiring. Built on a 12 AWG, 3-conductor configuration, this 250-foot roll delivers the current-carrying capacity needed for residential and light commercial circuits routed underground or through wet and corrosive indoor environments. The cable construction is highly resistant to acids, alkalis, corrosive fumes, chemicals, lubricants, and groundwater. It is noncorroding, sunlight-resistant, and will not support combustion. UL listed. Licensed electricians and electrical contractors install this wire in direct-burial applications where standard NM-B cable is not permitted.

Type UF-B is the required cable type when running branch circuits from a structure to an outbuilding, landscape lighting circuit, outdoor receptacle, or any below-grade wiring application governed by the National Electrical Code. It is also approved for use indoors in wet or corrosive locations where moisture exposure is a concern. The 3-conductor format supports standard 120-volt branch circuits requiring a hot, neutral, and ground conductor. This 250-foot roll is sized for typical residential yard runs and small commercial site work.

Key Features

• Rated for direct earth burial without conduit where permitted by code
• Sunlight-resistant jacket suitable for exposed above-grade runs
• Resistant to acids, alkalis, chemicals, lubricants, and groundwater
• Will not support combustion — added safety in enclosed or buried runs
• UL listed for underground feeder and branch circuit applications
• 250-foot roll reduces the need for mid-run splices on long circuits

Compatibility

Designed for use as an underground feeder cable in direct-burial branch circuit applications per NEC Article 340, and for wet or corrosive indoor locations requiring UF-B rated conductors.

Installation Notes

Installation must comply with NEC Article 340 and all applicable local codes, including minimum burial depth requirements, which vary by circuit voltage and whether conduit is used. Always de-energize the circuit and verify zero voltage at the panel before terminating conductors. Use appropriate weatherproof fittings and boxes at surface entry and exit points. A licensed electrician should perform or inspect all connections to panels and load-side devices.
