Encore Wire 101310800030 Nm-b Wire 12 Awg 250 Ft

Product Description

The ENCORE WIRE 101310800030 is a 12 AWG NM-B nonmetallic sheathed building wire rated for 600 volts and 20 amps. It features three solid copper conductors with PVC insulation and a combined nylon/PVC outer jacket in yellow. The cable carries a 90 degrees C temperature rating and an outer diameter of 0.345 inches. At 250 feet per coil, it is sized for standard rough-in wiring on 20-amp branch circuits. Licensed electricians install this wire during new construction and remodel work in residential and light commercial applications.

NM-B wire is used in dry, protected interior locations such as walls, floors, and ceilings of residential buildings. This 12 AWG, 3-conductor configuration is a common choice for 20-amp kitchen circuits, laundry circuits, and general-purpose branch circuits where a dedicated ground conductor is required alongside the hot and neutral. The yellow jacket color is the industry-standard identifier for 12 AWG NM-B cable, making circuit identification straightforward during rough-in and inspection.

Key Features

• 600-volt rating with 20-amp capacity on 12 AWG solid copper conductors
• 3-conductor configuration includes hot, neutral, and ground for code-compliant branch circuits
• 90 degrees C temperature rating for extended service life in typical interior installations
• PVC insulation with nylon/PVC outer jacket provides moisture resistance and mechanical protection
• Yellow jacket color provides instant visual identification as 12 AWG NM-B per industry convention
• 250-foot coil length reduces waste and suits standard residential rough-in runs

Compatibility

Designed as an NM-B type building wire for use in residential and light commercial wiring systems where NM-B cable is permitted by the National Electrical Code in dry, concealed locations.

Installation Notes

Installation must be performed by a licensed electrician in accordance with the National Electrical Code (NEC) and applicable local codes. De-energize and lock out the circuit or panel before making any connections. NM-B cable is approved for use only in dry, protected locations and must not be installed in conduit runs exposed to moisture, in direct burial applications, or in locations where physical damage is likely. Secure and support the cable at intervals required by the applicable code section.
