Southwire 63946855 Nm-b Building Wire 14 Awg 15 Amp

Product Description

The SOUTHWIRE 63946855 is a 14 AWG NM-B stranded copper building wire rated for 15 amps and 600 volts. It ships in a 250-foot length and is designed for use in residential and light commercial branch-circuit wiring. The white nylon jacket over PVC insulation provides moisture and tear resistance, making it suitable for dry and damp interior locations where NM-B cable is code-permitted. Licensed electricians install this wire during rough-in and service upgrades. With a maximum operating temperature of 194 degrees F, it handles the thermal demands of standard residential circuits reliably.

This wire is used in residential new construction and renovation projects where NM-B wiring methods are permitted by the National Electrical Code. Typical applications include 15-amp branch circuits serving lighting, receptacles, and small appliances. The stranded core offers flexibility during routing through framing, conduit stubs, and electrical boxes. The white jacket color follows standard industry color-coding for 14 AWG NM-B wire, helping electricians quickly identify conductor size on the job.

Installation Notes

Installation should be performed by a licensed electrician in accordance with the National Electrical Code (NEC) and applicable local codes. Always de-energize the circuit and verify absence of voltage at the panel before pulling or terminating wire. NM-B wire must not be used in wet locations, embedded in concrete, or run exposed in areas subject to physical damage. Staple or secure the cable at intervals required by NEC to prevent sagging or abrasion.
