10/2 NM-B Romex Cable, 250 ft vs Southwire Romex Simpull 10-2 NM-B Cable

Buy the 250 ft coil for a full branch circuit run; buy the 50 ft Southwire coil for a short dedicated circuit or a repair. Both are 10 AWG solid copper NM-B rated 600 V and 194 °F dry, so performance is the same. The real differences are length and jacket: Southwire's SIMpull jacket pulls and strips more easily, while the generic coil is the practical choice when you need distance. Owners of both report the same thing: solid copper NM-B is durable inside dry walls and fails only when overloaded or damaged.

• Choose the 250 ft coil if you are wiring a long 30-amp circuit, such as a dryer, water heater or subpanel feed, and want one continuous run without splices.
• Choose the Southwire 50 ft coil if you need a short run for a single outlet, a repair, or a job where a branded SIMpull jacket makes pulling easier.
