Southwire 28828255 250' 12-2 NM-B Cable with Ground – SIMpull, 12 AWG, Yellow

Product overview

Southwire Romex SIMpull 12-2 NM-B Cable with Ground delivers a practical wiring option for residential projects. The 250 ft spool provides flexible length for longer runs, and the bright yellow jacket helps quick identification on site. This copper NM-B cable is designed for dry, normally indoor spaces and is suitable for branch circuits powering outlets, switches, and other loads.

In everyday use, the cable’s durable exterior protects copper conductors while you work through walls, attics, or basements. While it offers flame and moisture resistance, it is not intended for wet locations, so plan installations in dry environments accordingly. The 600 volt rating aligns with typical residential electrical work, and the conductors are rated for temperatures up to 90°C, though ampacity is limited to 60°C for practical wiring scenarios.

Key benefits for homes and spaces

• General wiring for residences, farms, stores, and shops using a reliable NM-B design.
• Exposed or concealed runs in normally dry locations up to 90°C conductor temperature.
• Flame and moisture resistant construction with a 600 V rating for typical indoor use.
• Can be installed in air voids within masonry block or tile walls where conditions are dry.
• Copper NM-B conductor supports standard branch circuit needs for outlets, switches, and lighting loads.

Usage notes and installation tips

• Plan for dry locations only; do not use in wet or damp environments.
• Respect ampacity guidelines by applying the 60°C practical limit for conductors.
• Maximum conductor temperature rating is 90°C, allowing flexible installation options in dry interiors.
• Keep twisting and pulling to a minimum during installation to maintain conductor integrity.
