Whether you're tackling a home renovation, installing new lighting, or setting up outdoor power, electrical cables are the backbone of any safe and reliable electrical project. In this category, discover a wide selection of high-quality options like Romex NM-B for indoor residential wiring, UF cables for direct burial, heavy-duty extension cords, and specialized low-voltage wires, all designed to meet stringent safety standards and deliver dependable performance.
Understanding Electrical Cables and Their Types
Electrical cables come in various types tailored to specific applications, ensuring you get the right product for the job without compromising safety. Non-metallic sheathed cable (NM-B), commonly known as Romex, is ideal for indoor dry locations like walls and attics. Underground feeder (UF) cables are built tougher for wet or direct-bury scenarios. Extension cords provide flexible power reach for tools and appliances, while multi-conductor low-voltage wires suit LED lighting and automotive needs. Choosing the correct type prevents hazards and complies with electrical codes.
Key Features to Consider When Buying
To select the best electrical cable, focus on these essential factors:
- AWG Gauge: Lower numbers like 12 or 14 AWG handle higher amps; 12/2 means 12-gauge with two conductors.
- Conductors and Ground: Look for 2-wire with ground (W/G) for standard household use.
- Length and Coil Size: From 25 ft coils to 100 ft bulk, match to your project's scale.
- Jacket and Rating: PVC or SJTW for durability; UL-listed for safety assurance.
- Application Suitability: Indoor (NM-B), outdoor/waterproof (UF or SJTW), or low-voltage (UL 2464).
Brands like Southwire excel in user-friendly features such as SIMpull technology, which simplifies pulling wires through studs during installation.
Popular Products and Use Cases
Southwire's Romex SIMpull NM-B cables, available in 14/2 and 12/2 gauges in 25 ft or 50 ft coils, dominate for residential rewiring and new construction. For bulk needs, options like 100 ft 12/2 NM-B from ARIZONA ELECTRICAL SOLUTIONS offer value for larger jobs. Outdoor enthusiasts appreciate waterproof 50 ft 16/3 extension cords from PLUGTUL for garden tools or holiday lights.
Common scenarios include running power to garages or sheds with UF wire, extending reach in workshops with heavy-duty cords, or wiring low-voltage landscapes with 22-gauge 4-conductor cables from ENERJOUR. Pair these with items from our Electrical Boxes, Conduits & Fittings category for complete installations.

Frequently Asked Questions
What is the difference between NM-B and UF cable?
NM-B (Romex) is for indoor dry areas with a paper-wrapped ground; UF has a moisture-resistant solid jacket for outdoors or underground burial, though both are copper conductor cables.
Can Romex be used outdoors?
No, standard NM-B Romex is not rated for wet locations. Use UF cable or conduit-protected NM-B for exterior applications to maintain safety and code compliance.
What does 12/2 with ground mean?
It indicates 12 AWG (gauge) size, two insulated conductors (hot and neutral), plus a bare ground wire—suitable for 20-amp circuits in homes.
Are these cables UL-listed?
Yes, reputable products like Southwire Romex and listed extensions meet UL standards for fire resistance, insulation integrity, and ampacity.
How do I choose the right length?
Measure your run with some extra for pulls; shorter coils (25 ft) suit small jobs, while 50-100 ft options reduce splices in bigger projects.
