Southwire/coleman Cable 63947628 12/3 Nm-b Wire 100 Ft

Product Description

The SOUTHWIRE/COLEMAN CABLE 63947628 is a 100-foot roll of 12/3 non-metallic sheathed cable with ground, commonly known as NM-B or Romex-style cable. It features three 12 AWG copper conductors plus a ground wire, all enclosed in a thermoplastic outer jacket rated for 90 degrees C. This cable is used in standard residential and light commercial electrical rough-in work, supplying 120/240-volt branch circuits for outlets, appliances, and dedicated loads. Licensed electricians install this cable in dry, indoor locations inside walls, ceilings, and floor cavities where NM-B cable is code-permitted.

This 12/3 NM-B cable is well-suited for 20-amp branch circuits in residential construction and renovation. Common applications include kitchen appliance circuits, bathroom circuits, dryer feeds where a separate neutral is required, and other dedicated 240-volt loads. The 100-foot cut length is practical for single-room or single-circuit runs. It is sold as a single roll and is appropriate for use where the NEC permits non-metallic sheathed cable in dry, concealed locations.

Installation Notes

Installation must be performed by a licensed electrician in accordance with NEC Article 334 governing non-metallic sheathed cable. Always de-energize the circuit and verify zero voltage at the panel before pulling or terminating cable. NM-B cable is rated for dry locations only and must not be installed in wet, damp, or exposed outdoor environments. Secure and support the cable at intervals required by the applicable NEC edition and local amendments.
