Southwire/coleman Cable 63947621 12/3 Nmb Cable 25 Ft

Product Description

The SOUTHWIRE/COLEMAN CABLE 63947621 is a 25-foot cut length of 12/3 non-metallic sheathed (NMB) cable with ground, designed for residential and light commercial electrical wiring applications. Built with copper conductors and rated to 90 degrees C, this Romex-style cable delivers reliable performance in standard branch circuit installations. The 12 AWG, 3-conductor-plus-ground configuration supports 20-amp circuits commonly used for kitchen appliances, laundry equipment, and general-purpose outlets. It ships in a package quantity of 5 rolls, making it practical for stocking or multi-circuit jobs.

This cable is suited for interior residential and light commercial wiring where NMB (non-metallic sheathed) cable is permitted by local electrical code. Typical applications include branch circuits in dry, protected indoor locations such as walls, ceilings, and floors. The cut length format allows electricians to work from a manageable 25-foot section without handling a full spool, which is useful for shorter runs or service calls requiring a specific quantity.

Installation Notes

Installation should be performed by a licensed electrician in accordance with the National Electrical Code (NEC) and applicable local amendments. Always de-energize the circuit at the breaker panel and verify the absence of voltage before handling or terminating conductors. NMB cable must be installed in dry, protected interior locations and secured and supported per NEC Article 334 requirements. Do not install in conduit runs, wet locations, or exposed exterior applications unless the local authority having jurisdiction specifically permits it.
