Southwire 63950002 125ft 6-Gauge 3-Conductor NM-B Cable, Black | SIMpull Romex Indoor Grounded Cable

Overview

Meet the Southwire Romex SIMpull NM-B cable, a nonmetallic, grounded indoor option designed for normal dry locations. This 125 ft roll of 6-3 NM-B cable provides a flexible and scalable solution for residential wiring projects, delivering three conductors wrapped in a durable black jacket.

Designed for indoor use, the NM-B cable with ground is suitable for air voids in masonry or tile walls where the environment stays dry. The assembly carries a robust 600-volt rating, offering a practical balance of safety and performance for everyday electrical tasks around the home or small commercial spaces.

Key Benefits and Typical Uses

• Simplicity in pulling: SIMpull design helps installation teams advance cable quickly through walls and cavities.
• Indoor, dry locations: Optimized for normally dry spaces, minimizing exposure to moisture and damp conditions.
• Grounded NM-B construction: Includes a ground conductor for safer branch-circuit wiring in appropriate installations.
• Voltage and insulation specs: 600V rating supports common residential and light commercial circuits; nonmetallic sheath protects conductors.
• Length and configuration: 125 ft supply with 6-3 configuration (three conductors) for versatile branch wiring.

Specifications and Practical Considerations

This NM-B cable is intended for indoor, dry environments with a temperature rating not to exceed 90°C. It can be run in air voids within masonry block or tile walls if these walls are not wet or damp, offering flexibility in remodeling or new construction projects. Always verify local code requirements and ensure power is turned off before routing or connecting any wiring. The 600-volt rating provides a standard safety margin for typical residential circuits, while the grounded conductor enhances overall circuit reliability.

• Plan routes in dry spaces: Prioritize dry, non-moisture exposure areas to align with NM-B specifications.
• Check code compliance: Follow local electrical codes and labeling requirements during every step.
• Inspect before energizing: Verify insulation integrity and conductor connections after installation.
