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.

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.

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.

High-Temperature Power Cable

Unshielded

When others can't take the heat, this cable delivers power in ovens, furnaces, steel mills, and foundries. The PTFE jacket won't degrade and weaken as temperatures rise. It also resists abrasion, chemicals, oil, and moisture.

Fiberglass Fabric over PTFE and Mica Tape—A layer of mica tape, naturally heat resistant and electrically insulating, delivers superior protection against high temperatures.

Moisture-Resistant Control Cable

Safely wire control circuits in wet locations such as washdown areas. A water-blocking fiber tape under the jacket of this cable prevents swelling and protects your connection. Use this cable to control, monitor, and regulate stationary equipment such as sensors and PLCs. You can flex and bend this cable during installation and adjustments, but it isn't made for continuous motion.

Unshielded—Choose unshielded wires when electromagnetic interference (EMI) isn't a concern. Equipment such as motors and pumps may have voltage fluctuations and current spikes that distort signals.

Tight-Space Building Cable Strippers

Angled jaws let you insert building cable into the front of these strippers, so they’re useful in tight spots, such as inside electrical boxes. These tools remove the outer and inner insulation of NM-B cable. It’s the cable you’ll often find inside your walls running power to light fixtures and switches.

Armored Building Cable with Uninsulated Ground Wire

Also known as AC cable, this cable has an uninsulated aluminum ground wire that's in constant contact with the aluminum armor, so it can be used for bonding and grounding. The uninsulated ground wire is not counted in the number of wires. The armor acts as conduit to protect the THHN building wires. It's often used along the exterior of walls to carry power to outlet boxes. All are flame rated VW-1 to meet requirements for preventing the spread of flames based on a timed test with vertically suspended material.

Squeeze-and-Strip Building Cable Strippers

With just a squeeze, strip and remove outer insulation from your cable. These strippers require less effort than standard strippers or stripping knives because you don’t need to manually peel the insulation. The blade automatically adjusts to the outer diameter of your cable to remove a layer of insulation. They’re often used on NM-B cable (also known as Romex) since you can strip the cable jacket and the insulation on the individual wires without changing settings in between. Turn the adjustment knob to fine-tune the position of the blades so you don’t nick inner insulation, thin wires, or stranded wire. Set your strip length with the stop for consistent strips across multiple cables.

Building Cable Strippers

Remove the outer and inner insulation of NM-B building cable, commonly found inside your walls running power to light fixtures and switches. These strippers have a plier nose, which is useful for pulling and looping wire.

Steel—Steel strippers stay sharp with continuous use.

Stainless Steel—Stainless steel strippers resist corrosion and won't rust as quickly as strippers with steel blades when stored. They're best for less frequent use because their blades dull more quickly than steel blades.
