About Wire and Cable

Compare wire vs. cable and choose the right option based on gauge, number of conductors, insulation, and current rating.

Power Cable

Built for rough handling and frequent positioning, this cable delivers power you can count on. Use it for everything from extension cords to cords for hydraulic presses. Made to NEC Article 400 requirements, you can trust it to power whatever you need. Plus, the flexible jacket takes the struggle out of routing it through tight spaces and around machinery.

Armored Building Cable

Also known as metal clad (MC) cable, this cable has metal armor that acts as conduit to protect the building wires. It's often used along the exterior of walls to carry power to outlet boxes. It has a ground wire that is not counted in the number of wires.

Hazardous location environmental ratings indicate whether manufacturers have included safety features in products to facilitate their safe use in a hazardous environment. Before selecting a product for a hazardous location, ensure it is rated for your environment.

MC, THHN Solid Wire

Cable with THHN wire stands up to condensation and moisture in basements and other damp environments.

Harsh-Environment Power Cable

Type P Cable

Type P Cable with Bronze Armor

Transmit power in dirty, corrosive environments such as offshore rigs and ships. This cable is strong enough to resist crushing forces from heavy equipment. Its CPE jacket and tin-plated copper conductors maintain power in areas exposed to chemicals, oil, and salt water. It meets UL 1309 for high-performance marine cables, yet works just as well on land.

Bronze Armor—A layer of bronze armor between the two outer jackets boosts resistance to abrasion, impact, and crushing.

VFD Motor Cable

This cable is used in variable-frequency drive motors. It has a layer of braid and foil shielding that provides excellent protection against signal interference caused by voltage fluctuations and current spikes. The industry designation is WTTC, so it can be installed in cable trays or raceway in a wind turbine generator. It’s flame rated FT4 to meet requirements for preventing the spread of flames based on a timed test with material mounted to a vertical tray. The insulation resists oil.

Power Wire— Stranded with Cross-Linked Polyethylene Outer Jacket

With Three Uninsulated Ground

Wires

Cable with power wires sends electricity to run a motor.

Three Uninsulated Ground Wires—Cable with three uninsulated ground wires pairs a ground wire with each power wire, so you can create multiple circuits from the same cable. These wires aren’t counted in the cable’s number of wires.

No-Conduit-Required Control Cable

Unshielded

Made to TC-ER (Tray Cable, Exposed Run) standards, this crush- and impact-resistant cable eliminates the cost and hassle of installing conduit. It’s ideal for exposed runs, such as from a cable tray down to a control panel or motor control box. Support it every six feet to prevent sagging. You can flex and bend this cable during installation and adjustments, but it isn't made for continuous motion.

Building Cable


THHN Cable NM-B Cable	UF-B Cable THHN Cable

Rated for in-wall installation, this cable carries power to wall outlets. Also known as branch circuit wire, it can be used without conduit. It has solid THHN building wires, so the cable will stay in the shape you bend it. The uninsulated ground wire is not counted in the number of wires.

NM-B Cable—NM-B cable is for dry locations where moisture is not a concern, and often run through walls, ceilings, and concrete blocks.

UF-B Cable—UF-B cable is for wet locations where cable may be exposed to moisture or humidity. It's often used as underground feeder cable for pumps and lighting. The insulation resists moisture and UV light.
