Southwire wire-12-2wg Nm-b Cable 12/2 50 Foot Box

Product Description

The SOUTHWIRE wire-12-2wg is a solid copper, Type NM-B non-metallic sheathed cable with grounding conductor, packaged in a 50-foot box. NM-B cable is the standard wiring method for residential branch circuits, rated for dry, interior locations and suitable for use in wood-framed construction. The 12/2 configuration includes two current-carrying conductors plus a bare copper ground. This gauge is commonly used for 20-amp branch circuits serving outlets, appliances, and lighting in residential and light commercial applications. Licensed electricians install this product in compliance with the National Electrical Code.

Type NM-B cable in 12/2 is a go-to choice for residential new construction and renovation wiring. It is appropriate for branch circuits in wall cavities, floor joists, and accessible attic runs where the cable is protected from physical damage and moisture. The yellow jacket color coding identifies it as 12 AWG per NEC convention, making it easy to distinguish on the job site from 14 AWG white or 10 AWG orange-jacketed cable. The 50-foot box format is suited for shorter circuit runs or finish work where a full reel is unnecessary.

Key Features

• Solid copper conductors for reliable conductivity and code-compliant connections to standard receptacles and devices
• 12/2 configuration with bare copper ground conductor
• Type NM-B rating for dry, interior residential installations
• Yellow outer jacket provides quick visual identification as 12 AWG on the job site
• 50-foot box packaging reduces waste on shorter runs

Compatibility

Designed as a standard NM-B wiring solution for 20-amp residential branch circuits in dry interior locations per NEC Article 334.

Installation Notes

Installation must be performed by a licensed electrician in accordance with the National Electrical Code and applicable local codes. Always de-energize the circuit and verify absence of voltage at the panel before pulling or terminating cable. NM-B cable must not be installed in wet or damp locations, conduit exposed to moisture, or where subject to physical damage without additional protection. Staple or secure the cable at intervals required by NEC to prevent sagging or contact with sharp edges.
