10/3 UF-B Wire 50ft 100% Pure Copper 10AWG 3 - Direct Burial Cable

In this review of the 10/3 UF-B Wire 50ft spool, the bottom line is simple: this cable is aimed at homeowners, electricians, and contractors who need a durable, direct-burial 10AWG feeder that reduces installation time and conduit cost. The single biggest reason to buy is its ready-for-underground design combined with a full-size 10AWG ground, which makes it well suited for landscape lighting, outdoor outlets, and other damp or buried runs where a robust, weather-resistant cable is required.

Key Features

• 10AWG/3 configuration: Provides a full-size 10 gauge hot, neutral and 10AWG ground for 600V service, suitable for many outdoor feeder and branch circuits.
• Direct burial ready: The UF-B construction is engineered for burial without added conduit, saving time and piping expense during installation.
• Wide temperature tolerance: Rated to operate from -10C to 105C, it maintains stable performance in freezing winters and hot underground environments.
• PVC jacket protection: A waterproof and sunproof PVC jacket guards conductors from moisture, UV and soil exposure for outdoor longevity.
• RoHS compliant: Manufactured free from hazardous substances, meeting environmental safety expectations for installed wiring.

Who It's For

This cable is ideal for homeowners running landscape lighting, outdoor receptacles, or small feeder runs to outbuildings and agricultural equipment, plus electricians who want a time-saving direct-burial option. It is also a good choice for ground-mount solar array wiring where a robust, flexible conductor is needed.

Those who should look elsewhere include projects that require stranded conductors for special flexibility needs or installations that must meet a local code requiring conduit for physical protection; in those cases, use a stranded or conduit-rated alternative.

Pros & Cons

Pros

• Solid copper conductors and a full 10AWG ground deliver reliable electrical performance and good conductivity.
• Direct-burial construction saves labor and material costs by removing the need for conduit in many installations.
• PVC jacket is waterproof, sunproof and flexible enough for straightforward routing and termination.
• RoHS compliance adds reassurance about environmental and material safety.

Cons

• Not a stranded conductor cable, so it is less flexible than some stranded alternatives for tight bends.
• Length limited to 50ft per spool may require planning for longer runs or multiple splices.
