14/3 NM-B Wire with Ground 100FT - Solid Copper Residential Wire

In this review the 14/3 NM-B Wire with Ground 100FT is assessed for common residential wiring tasks. The reviewer finds this cable best for homeowners, electricians, and DIYers who need a flexible, durable 14 AWG three-conductor cable rated for indoor circuits; the single biggest reason to buy is the solid 99.99% oxygen free copper conductor and robust PVC construction that together deliver reliable conductivity and easier handling during installation. The review focuses on real-world installation, safety attributes, and whether it represents good value for typical outlet, switch and lighting runs.

Key Features

• 14 Gauge 3 Conductors: Provides the standard capacity and conductor count for many residential circuits, making it suitable for outlets and lighting runs.
• 99.99% Oxygen Free Copper: Enhanced conductivity reduces resistive loss and improves long-term corrosion resistance compared with lower-grade conductors.
• Temperature Rating: Rated from -10C to +90C, the cable tolerates a wide range of indoor temperature conditions encountered in basements and attics.
• Durable PVC Jacket: A high-grade outer sheath is flexible, flame retardant and water resistant, which eases pulling and protects conductors during installation.
• Grounded 3-Conductor Design: Includes a dedicated ground conductor for safer wiring of outlets, switches and lighting circuits in residential installations.
• Tested Manufacturing: Factory testing and RoHS environmental grade claims mean the product is intended to meet recognized safety and material standards.

Who It's For

The 14/3 NM-B 100FT cable is aimed at homeowners doing interior wiring projects, electricians installing branch circuits for multi-receptacle runs or lighting, and DIYers who want a ready length of solid 14 AWG cable with a grounded conductor. Its solid copper core and flexible jacket make it particularly useful where pulls through studs or short attic runs are common.

Those who should look elsewhere include installers who require stranded cable for vehicle or appliance hookups, and contractors needing outdoor or direct-burial cable since this is intended for residential indoor use. For higher ampacity or specific code-driven applications, verify local code before choosing this gauge and construction.

Pros & Cons

Pros

• High-purity oxygen free copper improves conductivity and long-term reliability.
• Flexible, flame-retardant PVC jacket makes pulling and stripping easier on typical residential runs.
• Wide temperature rating supports common indoor environments from cold basements to warm attics.
• Good value for the length and quality, as reflected by customer comments about durability and protection.

Cons

• Solid conductor is not ideal for applications that specifically require stranded wire or outdoor exposure.
• Not rated for direct burial or outdoor use, limiting some installation scenarios.
