Southwire 75 ft NM-B 8/3 — Black
Southwire’s 75-foot 8/3 NM-B cable is designed for indoor residential wiring of branch circuits. It is intended for installation above ground and in dry locations, rated up to 600 volts. The 8/3 configuration supports three conductors with a separate ground conductor, making it suitable for outlets, switches, and some 240V equipment located within dry indoor spaces. The extended length provides flexibility for longer runs without splicing.
Southwire 25 ft 8/3 with Ground — Woods SIMpull
Woods SIMpull NM-B cable features a patented SIMpull jacket designed to ease pulling and installation. It is intended for residential wiring of branch circuits for outlets, switches, and similar loads. The cable is UL Listed as NM-B and rated for 600 volts. The SIMpull design can simplify installation in tight spaces and through existing conduit or raceways, making this option suitable for interior residential projects with limited access points.
NM-B 8/3 Wire with Ground — 100 ft
This 100-foot NM-B 8/3 cable provides ample length for longer indoor runs while maintaining a 600-volt rating. The 8/3 configuration supports three conductors plus a ground and is suitable for residential branch circuits powering outlets, switches, and compatible 240V appliances when installed in dry indoor spaces. The wire is copper-based with an insulating jacket designed for easy pulling and grounding reliability.
50 Feet 8/3 Copper NM-B — Arizona Electrical Solutions
Arizona Electrical Solutions offers 8/3 NM-B cable with copper conductors and a color-coded jacket for easy identification. Rated at 600 volts with three conductors plus ground, this option is positioned for dry indoor residential use. The product notes indicate seven strands per conductor, which can affect flexibility and pulling characteristics during installation.
Arizona Electrical Solutions 25 ft 8/3 Copper NM-B
This 25-foot NM-B 8/3 copper cable provides a compact option for shorter indoor runs. It features a copper conductor with a color-coded jacket and a 600-volt rating. Suitable for residential wiring tasks such as branch circuits for outlets and switches in dry indoor spaces. The shorter length is beneficial for tight installations or limited run scenarios where longer cable would be unnecessary.
Buying Guide: Key Purchase Considerations
When selecting 8/3 with ground NM-B cable, several factors influence performance and safety. The following considerations help compare options from different brands and lengths:
- Voltage and current ratings: Ensure the cable is rated for 600 volts and appropriate current for the planned load. The 8/3 configuration typically supports up to 40 amps for many residential circuits, aligning with common subpanel and appliance requirements.
- Conductor material: Copper conductors provide reliable conductivity and durability. Some listings note seven-strand counts, which can affect flexibility during pulling and installation.
- Grounding and grounding conductor size: A dedicated ground wire (commonly 10 AWG in 8/3 cables) is essential for safety and equipment protection.
- Jacket and pulling ease: SIMpull or other advanced jackets can reduce friction and simplify installation through walls and conduits.
- Indoor use and environmental rating: Most NM-B cables are designed for dry indoor use. Avoid damp or wet locations unless the product is explicitly rated for such environments.
- Length and handling: Choose lengths that minimize splices and facilitate installation. Longer lengths may require careful pulling to prevent damage.
- Code compliance: Ensure the product complies with local electrical codes and is UL Listed for NM-B use in residential applications.
- Brand reliability and availability: Reputable brands like Southwire and XMK offer readily available products with consistent specifications and compatibility with standard fittings.
In summary, the best choice depends on your specific project: preferred length, ease of pulling, and whether you need a longer continuous run or a shorter, more maneuverable segment. For typical home renovations or new installations, a reliable 8/3 NM-B with ground from a recognized brand provides safe, compliant, and durable performance for outlets, switches, and certain 240V loads in dry indoor spaces.
