Wire 12-3wgnm-bcoils Nm-b 12/3 Branch Circuit Cable 250ft

Product Description

The WIRE 12-3wgnm-bcoils is a 12 AWG, 3-conductor NM-B non-metallic sheathed branch circuit cable with ground, supplied in a 250-foot coil. It uses solid copper conductors insulated with PVC and jacketed in nylon, rated for 600 volts and up to 20 amps at a 90 degrees C temperature rating. NM-B cable is the standard wiring method for residential branch circuits and is handled daily by licensed electricians on new construction and renovation projects. The 250-foot coil format reduces job-site waste and suits mid-size rough-in runs without the bulk of a full 1,000-foot reel.

This cable is suited for residential interior branch circuit wiring in dry or damp locations where NM-B is code-permitted. Typical applications include 20-amp kitchen appliance circuits, laundry circuits, bathroom circuits, and general-purpose receptacle and lighting branch circuits in wood-frame construction. The 12/3 configuration provides a hot, neutral, and ground conductor plus an additional insulated conductor, making it appropriate for multi-wire branch circuits or switched-outlet wiring. Electricians working under NEC Article 334 will find this cable compliant with standard residential wiring practice.

Key Features

• 12 AWG solid copper conductors rated for 20-amp branch circuits
• NM-B type construction with PVC insulation and nylon outer jacket
• 600-volt rating with 90 degrees C temperature rating
• 3-conductor with ground configuration for multi-wire and standard branch circuit use
• 250-foot coil format for manageable job-site handling
• Outer diameter of 347 mil for compatibility with standard NM fittings and staples

Compatibility

Designed for use in residential branch circuit wiring applications where NM-B type non-metallic sheathed cable is permitted by the National Electrical Code.

Installation Notes

Installation should be performed by a licensed electrician in accordance with NEC Article 334 and applicable local codes. De-energize and lock out the circuit panel before making any connections. NM-B cable must not be installed in conduit, embedded in concrete, or used in locations exposed to direct sunlight or physical damage without additional protection. Secure the cable at intervals required by code and protect it where it passes through framing members with nail plates as needed.
