Solid Indoor 14/2 NM-B Cable 100ft Coil
The Energeaster NM-B cable is a solid Indoor 14/2 with ground, rated for 600 volts. It features a coated jacket to ease pulling and installation in wall cavities and attics. Ideal for general residential branch circuits powering outlets and switches.
Best for: Homeowners planning longer runs inside walls where a single 100-foot coil reduces splicing. Better for: Projects needing easy installation with a reliable 600V rating. Choose this if: You want a straightforward, longer roll for mid-scale indoor wiring. Caution: The product data focuses on basic spec; verify local code requirements before use.
14/2 NM-B Wire With Ground – 10 ft
Premium copper conductors with a dual-layer jacket (PVC inner insulation and nylon outer jacket) provide enhanced protection against moisture, abrasion, and chemicals. Ground wire is kraft-wrapped for easy identification. Rated up to 600V and -10°C to 90°C, suitable for in-wall or conduit installations in dry locations.
Best for: Short indoor runs needing robust protection and easy pulling. Better for: Environments where moisture or abrasion resistance matters. Choose this if: you want a durable jacket and clean installation for outlets and switches. Caution: Grounding wire is paper-wrapped; handle with care to maintain separation during installation.
6/2 NM-B Wire With Ground – 10 ft
6 AWG NM-B with two current-carrying conductors plus a kraft-wrapped ground wire offers a robust option for higher load circuits. Dual-layer insulation combines inner PVC for electrical isolation and a tough nylon outer jacket for mechanical protection. Operates from -10°C to 90°C.
Best for: Lighting and outlets in high-heat or demanding spaces. Better for: Future-proofing circuits that may require higher current. Choose this if: you need heavier gauge copper for lower voltage drop on longer runs. Caution: Heavier gauge is stiffer; plan entry routes accordingly.
12/2 NM-B Wire With Ground – 50 ft
UL Listed 12/2 NM-B cable with solid copper conductors and a grounded conductor provides reliable performance for typical residential branch circuits. The flame-retardant PVC jacket protects the conductors during installation, and the flexible sheath supports quick pulling and clean stripping.
Best for: Standard indoor wiring projects for outlets, switches, and lighting. Better for: Homes needing a trusted, code-compliant 12-gauge option. Choose this if: you want predictable performance and easy installation. Caution: Data highlights general-use suitability; confirm conduit or wall cavity constraints in your space.
10/2 NM-B Wire with Ground – 50 ft
Indoors-ready 10/2 NM-B cable, 50 feet, includes ground. Similar to other NM-B cables, it uses a 600V rating and a jacket designed for easier pulling and stripping. Suitable for branch circuits powering outlets and general indoor loads.
Best for: Projects needing additional current capacity with longer runs in a dry indoor location. Better for: Upgrading smaller gauge circuits in older homes. Choose this if: you expect higher current while maintaining straightforward installation. Caution: 50 ft length may require splicing for longer runs; plan accordingly.
Buying Guide
What is NM-B cable and when should you use it?
NM-B stands for non-metallic sheathed cable with a thermoplastic jacket. It is commonly used for indoor residential wiring in dry locations such as walls and attics to power outlets and switches. Voltage rating is typically 600V, suitable for standard household circuits.
How do I choose gauge and number of conductors?
Common options include 12/2 and 14/2 with ground. Use 12-gauge ($12/2) for higher-load circuits or longer runs where voltage drop matters. Use 14-gauge for standard lighting and outlet circuits in dry, short-to-moderate runs. For heavier loads or longer distances, consider 6/2 or 10/2 with appropriate protection.
What should I consider for the jacket and insulation?
Look for a durable outer jacket (PVC or nylon-coated) and a design that resists moisture, abrasion, and chemicals. Dual-layer jackets offer extra protection in rugged indoor environments, while paper-wrapped grounds can aid identification during installs.
Safety and code considerations
Ensure installation complies with local electrical codes and NEC requirements. Cables must be rated for indoor use and installed in dry locations unless specifically rated for wet locations. Always power off circuits before work and confirm proper grounding and secure connections.
How to plan your run and avoid common issues
Measure the total length, account for bends and pulls, and choose lengths with minimal splices. Use staples or clamps recommended for NM-B to avoid damaging the jacket. Keep conductors away from sharp edges and heat sources to maintain insulation integrity.
Material and installation notes
Most options include ground conductors and share a 600V rating. The main differences are jacket materials (PVC, nylon outer jacket), conductor purity (copper quality), and length. For longer runs or higher loads, heavier gauges may be preferable to reduce voltage drop.
FAQ
- Q: Is NM-B suitable for outdoor use? A: No, NM-B is intended for indoor dry locations unless specifically rated for exterior use.
- Q: What does “with ground” mean? A: It includes a grounding conductor to help protect against electrical faults.
- Q: Can I use 14/2 for lighting circuits? A: Yes, 14/2 is common for standard lighting and outlets in dry indoor spaces.
- Q: How long should I run to avoid voltage drop? A: For typical home runs, 50–100 feet is common; longer runs may require heavier gauge to minimize drop.
- Q: Do these cables require special tools? A: Basic hand tools and a cutter/stripper appropriate for copper conductors are typically enough; follow local code for fastening and protection.
