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

Southwire 500 ft. 14/1 Solid THHN Building Wire

Equip your electrical projects with a dependable THHN solution designed for indoor conduit runs. This 14 AWG solid copper conductor delivers consistent performance, code-compliant safety, and durable construction to keep circuits protected from start to finish.

Why this THHN wire stands out

  • Conductor: Solid 14 AWG copper for straightforward pulling and stable voltage delivery.
  • Insulation & jacket: PVC (thermoplastic) insulation with a rugged nylon jacket for enhanced abrasion resistance in conduit and tight spaces.
  • Voltage & temperature ratings: Rated for 600 V and up to 90°C, supporting a range of standard building circuits.
  • Amp rating: 15 A capability aligned with typical residential and light commercial branch circuits.
  • Conductor configuration: 14/1 (one solid conductor) for clean, single-run installs.
  • Location suitability: Indoor use with wet location compatibility and UV resistance, expanding where this wire can be deployed.
  • UL Listed & flame retardant: Built to meet safety standards and reduce risk in electrical installations.
  • Direct burial: Not intended for direct burial; use within conduit or raceways as specified.
  • Grounding: Copper ground material to support proper grounding paths.
  • Color & length: Yellow jacket helps identification, with a long 500 ft reel for extensive projects.

Ideal applications

  • Indoor conduit runs for residential and light commercial wiring
  • Branch circuits, panel wiring, and short to moderate-length installations
  • Situations requiring a durable nylon jacket for added abrasion resistance
  • Projects where wet location flexibility is beneficial, including basements and garages

Note: This product is 500 feet in length, with a single solid 14 AWG copper conductor, PVC insulation, and a nylon outer jacket. It’s UL Listed, flame retardant, and rated for 600 V and up to 90°C.

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.
