Southwire UF-B Underground Feeder Cable, 12/2 AWG, 250 ft
Key features include availability with 2 or 3 conductors, with or without a ground wire. Conductors are annealed copper, wrapped in PVC insulation and a color-coded jacket for easy identification. The 250 ft length supports extended runs without frequent splicing, making it suitable for outdoor lighting, garden features, and direct burial applications. The rugged jacket resists moisture exposure while maintaining electrical integrity in damp or wet environments.
Southwire Outdoor Wire, 12/2WG UF 100 Ft Coil
Designed for direct burial wiring in outdoor environments, this UF cable features a sunlight-resistant jacket, flame retardant properties, and moisture/corrosion resistance. It is intended for outdoor feeder runs to lighting and fixtures, with suitability for damp, moist, wet, or dry locations. UL listed, the cable supports robust outdoor installations that require long, buried runs without conduit in some cases.
FIRMERST 12/2 UF Wire Outdoor Direct Burial 150 ft
This UF-B 12 AWG cable uses a solid copper conductor with a ground wire and a PVC jacket rated for direct burial at up to 600 volts. It is ETL-listed and suitable for both dry and wet locations, with UV resistance to withstand outdoor exposure. The 150 ft length minimizes splices on longer outdoor runs, providing reliable, continuous power to exterior fixtures or equipment.
Southwire 12/2WG UF Wire 50-Foot
This 50-foot version is well-suited for shorter direct burial runs to outdoor lighting or outbuildings. It features a UV-resistant jacket and a UL-listed, direct burial rating. The 12/2 construction with two conductors plus ground or without depending on configuration provides flexibility for varying installation needs such as lighting, irrigation pumps, and exterior outlets.
Southwire 12/2 Gray Solid CU UF-B W/G Wire, 25 ft
Compact 25 ft runs are ideal for short, direct burial projects or feeder drops to secondary outdoor loads. The solid copper conductors with a ground wire or without provide stable electrical performance, while the PVC jacket and weather-ready design support exterior installations in damp or wet environments. UL listed status reinforces its suitability for residential outdoor use.
Buying Guide
Choosing the right UF-B 12/2 cable involves several considerations to ensure safe, code-compliant installations and dependable performance:
- Conductor type: Solid vs stranded copper. Solid copper offers lower resistance for fixed runs, while stranded copper can be more flexible for bends and routing around obstacles.
- Ground presence: Decide whether the configuration requires a ground wire included in the conductors. Grounding improves safety for outdoor loads.
- Jacket material and rating: Look for UV resistance, moisture resistance, and flame retardancy based on exposure and local codes. Direct burial ratings are essential for underground runs without conduit where allowed.
- Voltage rating: Confirm the cable is rated for the intended environment (commonly 600 volts for residential outdoor use).
- Length and installation: Plan runs to minimize splices. Longer lengths reduce the number of connections but ensure the chosen product is rated for the burial conditions.
- UL/ETL listings: Certifications indicate compliance with safety and performance standards for exterior installations.
- Environmental considerations: Proximity to moisture, soil salinity, and potential sunlight exposure may influence jacket choice and burial depth.
- Code compatibility: Local electrical codes may specify burial methods, conduit requirements, and acceptable UF cable configurations for outdoor installations.
Comparative considerations across the showcased options include length variety, stranded versus solid conductors, presence or absence of a ground wire, jacket durability, and direct burial suitability. For longer exterior runs, a 150 ft or 250 ft option reduces the number of splices, while shorter coils are handy for compact projects such as lighting at an outbuilding or a garden feature. In all cases, adhere to safe burial practices and verify local code compliance before installation.
