10/2 NM-B 10 Gauge Wire 25ft Coil - Indoor Copper Cable

In this review of the 10/2 NM-B 10 Gauge Wire 25ft coil, the bottom line is clear: this cable is aimed at DIYers and electricians who need a short run of solid copper NM-B for indoor branch circuits. The reviewer found the orange jacket and solid 10 gauge conductors straightforward to work with, and the product's 600 volt rating and Type NM-B construction make it suitable for standard residential wiring inside walls and attics. For anyone replacing or extending outlet and switch circuits in dry locations, the cable delivers reliable conductor quality and easier pulling thanks to its coated jacket.

Key Features

• Solid 10 gauge conductors: Provides a thicker, durable copper path for typical 30 A branch circuits where 10 gauge is required.
• 25 ft coil length: A convenient short-run length that reduces waste when making small repairs or additions to existing circuits.
• NM-B 90 C rated jacket: Rated for indoor building wiring at up to 600 volts and suitable for use in wall cavities and attics in dry locations.
• Coated cable jacket: Smooth orange jacket makes the cable easier to pull, strip, and route through framing spaces and chase areas.
• Ground conductor included: The solid 10 gauge ground is laid parallel and wrapped with fire-retardant paper for safety and consistent grounding.
• Two insulated conductors: Black and white insulated conductors run parallel for clear identification and installation.

Who It's For

This cable is best for home handymen, electricians doing small projects, and anyone who needs a short length of 10/2 NM-B for a branch circuit to power an outlet, range hood, or other 30 A-capable device in dry indoor spaces. The 25 ft coil makes it practical for short extensions, repairs, or prototype wiring without buying bulk spools.

Those who should look elsewhere include professionals planning long runs or commercial installers who need metal-clad cable or wire rated for damp or wet locations; this NM-B product is intended for dry, indoor applications only and is not suitable where moisture protection or metallic armor is required.

Pros & Cons

Pros

• Solid copper construction gives a thick, dependable conductor favored for branch circuits.
• Orange, coated jacket pulls and strips cleanly, making installation quicker in tight spaces.
• Includes a full-size solid ground conductor, improving safety and grounding continuity.
• 25 ft coil length reduces excess material for small jobs and repairs.

Cons

• Limited to dry, indoor use; not rated for wet locations or outdoor burial.
• Short 25 ft length may not suit larger projects that need longer continuous runs.

Frequently Asked Questions

Can this cable be used outdoors?
No. This NM-B cable is intended for dry, indoor use in wall cavities and attics and is not suitable for outdoor or wet locations.

Is the ground conductor the same gauge as the hot and neutral?
Yes. The ground is a solid 10 gauge conductor laid parallel with the insulated conductors for proper grounding.

What kinds of circuits is this cable typically used for?
It is commonly used for residential branch circuits such as outlets and switches that require 10 gauge wiring for higher current needs in dry indoor areas.
