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.

  • Guaranteed authentic · No counterfeits, no gray-market resellers

About Product Overview

This is Southwire's 10/3 Romex NM-B with ground, a solid-copper non-metallic cable built for circuits that need 10-gauge wire and a dedicated ground - think electric water heaters, some dryers, and other 30-amp branch circuits. The 250-foot coil gives you enough length to run a full circuit on most jobs without splicing mid-run, which means fewer connections and less troubleshooting down the road.

The nylon jacket resists abrasion during pulls through studs and joists, and Southwire rates this cable for sunlight/UV exposure, so it holds up if a run gets exposed temporarily during construction. It's rated for indoor use and carries a 90°C temperature rating with a 600-volt rating, giving you margin on both heat and voltage for standard residential and light commercial wiring. UL listing means it meets recognized safety standards, and the flame-retardant jacket adds another layer of protection once it's behind the wall.

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.
