Best 12 / 2 With Ground Electrical Wires for Home Wiring
Comprehensive guide to 12/2 with ground NM-B electrical wire for residential wiring. This article highlights top choices for different needs—from compact runs in closets to long runs in new builds. Best for residential outlets and lighting circuits, these cables are rated for 600V and designed for indoor use. The featured selections cover varying coil lengths and jackets to suit different installation scenarios.
Buyer type overview:
– First-time homeowners and DIY enthusiasts: choose flexible pulling and common lengths like 25–50 ft.
– Renovators and electricians working in larger homes: opt for 100–250 ft coils to minimize splices.
– Projects emphasizing ease of installation: look for coated jackets and SIMpull technologies.
– Budget-focused buyers: compare 100 ft vs 250 ft coils for cost-per-foot without sacrificing safety.

Energeaster 12/2 Solid Indoor NM-B with Ground – 100 ft
Features: Solid indoor 12/2 NM-B cable; 100 ft coil; coated jacket for easier pulling and installation; 600V rating; copper conductors. Best for: homeowners and installers who need a reliable, mid-length run for outlets and switches inside walls or attics. Limitation: longer runs may require additional junctions or supports in tight spaces.
Energeaster 12/2 Solid Indoor NM-B – 50 ft
Features: 50 ft coil; coated jacket; 600V rating; indoor NM-B copper wire. Best for: small-scale projects like confined attic runs or ceiling-to-switch connections. Caution: shorter coils may require more fittings or splices on larger layouts.
Energeaster 12/2 Solid Indoor NM-B – 25 ft
Features: 25 ft coil; jacket-coated for easier install; 600V rating; copper conductors. Best for: quick-wire replacements and small interior runs. Limitation: very short length may increase connections and time for larger installations.
Imperium Cable 12/2 NM-B – 250 ft
Features: 250 ft coil; solid copper conductors; yellow jacket; 600V rating. Best for: long runs with fewer splices, ideal for new construction or retrofit projects in single-family homes. Caution: ensure proper securing and protection in open stud bays to prevent damage to the jacket.
CIRENKO 12/2 NM-B Cable – 100 ft
Features: UL Listed; two insulated 12 AWG conductors plus bare ground; indoor use in dry locations; 600V rating implied by NM-B. Best for: residential indoor wiring where UL listing is preferred. Limitation: data emphasizes dry locations; avoid damp or outdoor spaces without protection.
ARIZONA ELECTRICAL SOLUTIONS NM-B 12/2 – 100 ft
Features: 100 ft coil; meets ASTM B-3, B-8, NFPA 70 standards; 600V rating; 2 conductors with ground; yellow jacket. Best for: standard indoor residential circuits that require compliance with multiple electrical standards. Limitation: data does not specify jacket thickness; verify compatibility with local codes for dense installations.
Buying Guide: Key Purchase Considerations
- Length needs: Longer runs reduce splices but increase difficulty during installation. Choose 100–250 ft coils for main runs; 25–50 ft for shorter, interior connections.
- Jacket color and jacket quality: Yellow jackets typically indicate NM-B; SIMpull or coated jackets ease pulling and installation in walls and attics.
- Voltage rating and intended use: NM-B copper cables are rated for 600V and designed for indoor use in dry locations.
- Conductor material: All listed products use copper conductors (solid copper preferred for permanent wiring), which provides better durability and reliability than copper-clad options.
- Code compliance: Look for UL listings and adherence to NEC requirements for residential indoor wiring. Check local amendments as needed.
- Best-for scenarios:
– Short runs in tight spaces: 25–50 ft coils with jacket ease.
– Longer, uninterrupted runs: 100–250 ft coils to minimize splices.
– Indoor wall/attic installations: coated jackets for easier pulling and protection against abrasion.
FAQ
- What does 12/2 with ground NM-B mean?
Answer: It refers to a non-metallic sheathed copper cable with two insulated conductors and a bare ground conductor, rated for indoor use and up to 600V. - Is NM-B suitable for outdoor use?
Answer: No. NM-B is intended for indoor, dry locations. For outdoor or wet locations, use weather-rated or conduit-protected cable. - What is the advantage of a longer coil like 250 ft?
Answer: Longer coils reduce the need for splices and can lower per-foot costs in large installations, but may be harder to maneuver in tight spaces. - Should I choose copper or copper-clad aluminum (CCA)?
Answer: Copper conductors offer better conductivity and durability in typical residential wiring; CCA is usually a lower-cost alternative but with lower performance in long-term use. - What safety standards should I look for?
Answer: UL listings, NFPA 70 (NEC compliance), ASTM standards, and REACH/RoHS compliance indicate reliability and safe installation.
