12/2 UF-B Wire 250FT 100% Pure Copper - Direct Burial Durable Cable

In this review the 12/2 UF-B Wire 250FT is judged for homeowners, contractors and DIYers who need a reliable direct burial feeder cable. The bottom line: this cable stands out because it uses 100% oxygen free copper conductors and a heavy PVC jacket rated for wet and corrosive locations, making it a practical choice when durability and conductivity matter most for outdoor and underground runs.

Key Features

• 100% Oxygen Free Copper: Provides higher conductivity and greater current capacity than copper-clad alternatives, helping reduce voltage drop on longer runs.
• 12 AWG 2 Conductors with Ground: Standard 12/2 configuration with a 12AWG ground suitable for general branch circuits and feeders up to three stories above ground.
• Wide Temperature Rating: Rated -15C to +105C so it holds up in both cold and hot environments without losing flexibility or safety.
• Waterproof and UV Resistant Jacket: Thick PVC sheath resists sunlight, moisture, snow and abrasion for long life in harsh outdoor or direct burial installations.
• 600V Voltage Rating: Rated for 600 volts, meeting common residential and outdoor electrical needs without special handling.

Who It's For

The 12/2 UF-B is aimed at homeowners running outdoor lighting, pumps or feeders, plus electricians needing a reliable, direct burial cable for wet or corrosive locations. It is a sensible pick for projects where a robust jacket and OFC conductors reduce concern over oxidation and ensure steady current delivery.

Those who need thinner indoor-only cable or specialized high-voltage wire should look elsewhere; this product is designed for general branch circuits and underground feeders rather than fine control wiring or appliance-specific connectors.

Pros & Cons

Pros

• Heavy duty construction with a durable PVC jacket makes it suitable for direct burial and exposed outdoor runs.
• Customers report the cable feels substantial and is good value for money, matching the claims of solid copper construction.
• Wide temperature and 600V ratings add versatility for many residential and light commercial uses.

Cons

• At 250 ft, it can be heavy and less maneuverable for single-person handling on long pulls.
• Not intended for specialized applications that require non-PVC jackets or different voltage classes.
