Southwire 10/2 NM-B Romex Wire 100 ft vs Southwire Romex Simpull 10-2 NM-B Cable

Both are the same Southwire Romex SIMpull 10/2 NM-B cable with ground, so the choice comes down to length and packaging, not performance. The 100-foot coil suits a full branch circuit run or several short runs; the 50-foot coil suits a single dedicated circuit such as a 30-amp dryer, water heater or AC feed. Build, jacket and conductor quality are identical, and owners of Romex generally report the jacket pulls and strips cleanly. Buy the length that matches your run and avoid splicing short coils together.

• Choose the Southwire 100-foot 10/2 NM-B if your run is long or you have several circuits to wire and want one continuous coil.
• Choose the Southwire 50-foot 10/2 NM-B if you are wiring one dedicated 240-volt circuit and want less leftover cable.
