In-Store Exclusive

This one's worth the trip to the store.

Brands like Weber, Milwaukee, Yeti, and DeWalt restrict where their products can be sold online — and for good reason. In-store buyers get authentic products, full manufacturer warranty, and access to pricing that simply isn't allowed to be advertised on the web.

  • Authorized dealer network · Full manufacturer warranty & support
  • Guaranteed authentic · No counterfeits, no gray-market resellers
  • The brands set these standards · Be wary of sellers who don't follow them

Every order helps keep your local hardware store on the corner.

Why we built NHG
You might find it for less locally. Independent retailers often offer competitive pricing — some products are even cheaper in-store than online.
Real expert advice — not search results. Independent hardware staff know their inventory and the local conditions you're working in.
Keep the neighborhood working. Every dollar spent at an independent retailer returns roughly 3x more to your local economy than at a national chain.

About Product Overview

Power your outdoor installations with confidence using the Southwire 250 ft. 12/3 Solid Type UF-B WG Underground Feeder Underground Cable. Built for direct burial and outdoor reliability, this 12/3 UF-B WG cable delivers a durable, residential-grade power run for landscapes, outbuildings, and exterior equipment.

Key specifications at a glance

  • 12 AWG solid copper with a 12/3 configuration and a dedicated ground wire
  • Voltage & amp capacity: 600V rated, suitable for typical 20-amp circuits
  • Construction: Solid copper conductors, PVC insulation, nylon jacket for abrasion resistance
  • Direct burial & environmental readiness: Direct burial approved (underground use), wet location capable, UV-resistant exterior
  • Temperature rating: 90°C for versatile indoor/outdoor performance
  • Protection & integrity: Flame-retardant jacket provides an extra safety margin in outdoor installations
  • Appearance & length: Gray jacket, 250 feet in a single run for longer trench-free installs
  • Compliance: UL listed, designed to meet established electrical safety standards

Why this UF-B WG cable stands out

  • All-in-one underground feeder solution: Thick PVC insulation paired with a durable nylon jacket creates a robust line that withstands moisture, soil abrasion, and temperature swings typical of outdoor environments.
  • Direct burial convenience: No conduit required for many outdoor feeds, enabling faster, cleaner installations for landscape lighting, irrigation pumps, and subpanels in small outbuildings.
  • Three conductors with a solid ground: Two hot conductors plus a solid ground provide a straightforward wiring configuration for reliable power delivery to external equipment.
  • Flexibility for outdoor projects: The 250-ft length helps minimize splices and allows longer runs from a subpanel or main feeder to remote outdoor loads.

Ideal uses

  • Outdoor lighting circuits, landscape features, and decorative lighting runs
  • Power feeds to irrigation systems, pumps, pool equipment, or hot tubs located underground
  • Feeding outbuildings, workshops, or detached garages where a direct burial feeder is preferred

Practical installation notes

  • Verify that your circuit load aligns with a 20-amp capacity and that the installation complies with local electrical codes.
  • Choose the UF-B WG option when you need a proven underground feeder with direct burial capability and outdoor durability.
  • Use proper burial depth, protection, and bonding practices as specified by code to ensure long-term performance.
  • Store unused length and handle with care to preserve the integrity of the nylon jacket and PVC insulation.

Their Counter
Try local first · we'll wait

The stores we send you to are local and independently run — often for generations, the kind of place where someone behind the counter knows the regulars. We don't own them. We just think they deserve the foot traffic. They can put most of what we sell on their next truck. Ask there before you check out here.

About our directory. National Hardware Group is an independent retailer and directory. The local stores we list and link to are separately owned and operated — we have no ownership stake in any of them, and most pay us nothing to be included. That includes plenty of stores flying a co-op banner that people don't realize are locally owned and run, not operated by a corporation. Store owners can choose to upgrade their listing for an enhanced presence or pickup features, but the base directory is free, and inclusion is never a paid endorsement.
