Energeaster Solid Indoor 12/2 NM-B Cable, 25ft Coil – 12 Gauge, 2 Conductors with Ground (Yellow)

Overview

Energeaster Solid Indoor 12/2 NM-B Cable is a dependable copper wiring option designed for indoor residential projects. Supplied as a 25-foot coil, the cable features a high-visibility yellow jacket that helps identify the run quickly during installation. With a 600-volt rating and 90°C NM-B insulation, this wire is suited for indoor branch circuits that power switches and outlets inside walls and attics.

This cable is built for practical, real-world use. The solid 12-gauge conductors are paired with a solid ground wire, all arranged with the ground interposed between the insulated lines and wrapped in a fire-retardant layer for added safety. The jacket is designed to ease pulling, stripping, and overall installation, reducing friction as you route the wire through stud bays and an attic crawlspace.

Key specifications

• Solid indoor 12/2 NM-B copper cable, 25 ft coil, jacket-coated for smoother pulling and stripping
• Type NM-B insulation rated up to 90°C, suitable for indoor walls, attics, and concealed runs
• Two 12-gauge solid conductors with a 12-gauge ground wire; all conductors are copper
• Yellow jacket color for quick identification and organized wiring layouts
• Voltage rating of 600 volts, appropriate for standard residential power distribution
• Ground wire wrapped with fire-retardant material and laid parallel between insulated conductors

What this means for your project

• Indoor reliability: Ideal for branch circuits that feed switches and outlets inside walls and attics.
• Ease of installation: Jacket-coated for smoother pulling and simpler stripping, saving time on site.
• Durable construction: Copper conductors with a solid ground wire provide a sturdy, safe wiring option for residential use.
• Clear identification: Yellow jacket helps you distinguish NM-B runs at a glance.
• Safety and compatibility: 600V rating supports typical household electrical loads; 90°C insulation offers additional heat tolerance in indoor spaces.

Tips for installation and guidelines

• Install only in dry indoor locations; NM-B is not recommended for damp or wet locations.
• Follow local electrical codes and best practices when routing cable through walls, ceilings, and attics.
• Keep the 25 ft coil length within the allowed run distances for your project to minimize splices.
• Use proper strain relief and connectors at panels and boxes to ensure a safe, secure connection.

Overall, Energeaster 12/2 NM-B cable offers a practical combination of copper performance, indoor suitability, and ease of handling. It’s a solid choice when wiring residential branch circuits inside walls and attics, provided location and code requirements are observed.
