50ft NM-B 8/3 Wire With Ground — XMK
This UL-listed 8/3 NM-B cable features three copper conductors plus a ground, rated at 600 volts and 40 amps. It is designed for dry indoor residential wiring and is suitable for branch circuits powering outlets, switches, or large loads such as ranges and HVAC equipment. The 10 AWG ground wire helps ensure a robust grounding path. The jacket is RoHS-compliant, and the cable is intended for dry environments like garages and basements. Its versatility includes use in conduit or concealed installations, making it a practical pick for many indoor applications.
Southwire 8/3 Romex NM-B W/g — 125 ft
Southwire’s Type NM-B cable is a staple for residential and commercial branch circuits. This 8/3 with ground version supports installations above ground in dry locations and is approved for service up to 600 volts. Ideal for runs to subpanels, outlets, and other 120/240-volt loads, its copper conductors and robust insulation provide dependable performance in typical indoor environments. While designed for dry spaces, users should avoid wet or damp locations to preserve insulation integrity.
Southwire 75 ft 8/3 NM-B — Dry Indoor Use
Southwire’s 75-foot NM-B 8/3 cable is designed for residential and commercial branch circuits in dry indoor locations. This cable is rated for up to 600 volts and features copper conductors encapsulated in a nonmetallic jacket for easy installation. The length makes it suitable for longer circuit runs such as feeding multiple outlets or a subpanel in a garage or utility room. As with other NM-B cables, it should not be used in wet or damp locations.
Southwire 25′ 8/3 with Ground — SIMpull
This SIMpull NM-B cable from Southwire is coated with a patented SIMpull jacket designed to ease pulling and installation. It remains suitable for dry indoor environments and is commonly used for branch circuits powering outlets and switches. The jacket is designed to reduce resistance when routing through walls and conduit, helping to streamline installations in homes where length and ease of handling matter most.
NM-B 8/3 Wire With Ground — 100ft
This 100-foot NM-B 8/3 cable mirrors the same core specs: three insulated copper conductors plus a 10 AWG ground wire, rated for 600 volts and 40 amps. It is suitable for dry indoor use, including garages, basements, or utility rooms. The longer length reduces the need for splices and helps manage routing through walls or joists. As always, avoid damp locations to maintain insulation integrity.
50 Feet 8/3 Type NM-B Copper — Arizona Electrical Solutions
Arizona Electrical Solutions offers 8/3 NM-B with a color-coded jacket for easy identification and 600-volt rating. This 50-foot option is convenient for mid-length runs in dry indoor installations, such as feeding switches and outlets in a home. It emphasizes copper conductors and a standard 3-conductor plus ground configuration, making it a straightforward choice for typical residential wiring tasks.
Arizona Electrical Solutions 8/3 Type NM-B Copper — 25 ft
This 25-foot NM-B 8/3 cable is designed for compact runs with dry indoor use in mind. It uses copper conductors and a color-coded jacket to simplify identification during installations such as indoor branch circuits for outlets and switches. It is a practical option when shorter lengths are needed for shorter runs or tight spaces in residential projects.
Buying Guide: Key Purchase Considerations
- Voltage and ampacity: All listed options are rated for 600 volts and typically support up to 40 amps. Confirm the circuit requirements and local electrical codes before selecting a cable.
- Environment: These NM-B cables are designed for dry indoor locations. Avoid use in damp or wet areas to prevent insulation damage and potential hazards.
- Conductor material: All options use copper conductors, which offer excellent conductivity and durability for residential wiring.
- Jacket type: NM-B jackets vary from standard to SIMpull. SIMpull jackets can simplify installation by reducing friction when pulling through walls and conduits.
- Length: Choose lengths that minimize splices and facilitate cleaner routing. Longer runs may reduce the need for additional connectors but require careful handling during installation.
- Grounding: Ensure the ground conductor is included (8/3 with ground) and properly connected to grounding paths in your panel and devices for safety compliance.
- Code compliance: Verify that the product is UL-listed and RoHS-compliant where applicable, and match local codes for residential wiring projects.
- Installation tips: Plan routes to avoid moisture exposure, protect cables from physical damage, and use appropriate conduit or raceways where required.
In summary, these 8/3 NM-B cables with ground offer reliable choices for residential wiring projects that require feeding outlets, switches, or heavy appliances. Whether you prioritize length, ease of pulling, or standard dry-location performance, the options above provide solid baselines for safe, code-compliant installations.
