About Wire and Cable

Industrial Communication-Standard Cable

Connect devices such as sensors, programmable logic controllers, and actuators to an automated network.

Audio Cable

Hook up speakers, intercoms, and other low-current devices to a building's communication wiring.

Cable

Use this general purpose cable to supply power to equipment.

Low-Voltage Cable

Rated to 12 volts DC, this cable is often used in low-voltage applications such as battery and vehicle wiring and radios. Also known as GPT cable.

Direct-Burial Cable

Weather-resistant insulation makes this cable suitable for outdoor use and direct burial without conduit.

Appliance Cable

Also known as zip cord, this cable is often used in lamps, heat guns, and other small appliances.

Drop-Down Cable

Often used to wire pendant switches, this cable hangs from an overhead connection. Also known as bus drop cable.

Control Cable

Send signal and data to operate, measure, or regulate automated equipment such as conveyors and CNC machines.

No-Conduit-Required Control Cable

This cable meets TC-ER crush and impact requirements for exposed runs in cable trays, so it can be used without conduit. It sends signal and data to operate, measure, or regulate automated equipment.

Water-Block Control Cable

Keep water from damaging wires—this cable has a layer of absorbent material that traps moisture before it reaches the internal wires. It sends signal and data to operate, measure, or regulate automated equipment.

Continuous-Flex Cable

Often used in automated applications such as robotics and cable carriers, this cable withstands continuous motion without degrading data or signal transmission.

Communication and Security System Cable

Connect low-current circuits such as intercoms and security systems to a building's electrical system in single-level facilities.

Duct-Rated Communication and Security System Cable

Also known as plenum cable, this cable has low-smoke insulation and can be used without conduit in ductwork and above a drop ceiling. Use it in low-current circuits such as intercoms and security systems.

Riser-Rated Communication and Security System Cable

This cable is approved for use in vertical shafts and large facilities with multiple levels. It's often used for low-current circuits such as intercoms and security systems.

Armored Building Cable

The metal armor on this cable acts as conduit to protect the internal wires. It's often used along the exterior of walls to carry power to outlet boxes. Also known as MC cable.

Armored Building Cable with Uninsulated Ground Wire

This cable has an uninsulated ground wire that touches the protective metal armor so it can be used for bonding and grounding. It's often used along the exterior of walls to carry power to outlet boxes. Also known as AC cable.

Building Cable

Rated for in-wall installation, this cable carries power to wall outlets. Also known as branch circuit wire.

Thermostat Cable

Hook up thermostats, air-conditioning units, and other low-voltage equipment.

Duct-Rated Fire Alarm Cable

Also known as plenum cable, this cable has low-smoke insulation and can be used without conduit in ductwork and above a drop ceiling. Use in critical circuits such as fire alarms and smoke detectors.

Riser-Rated Fire Alarm Cable

This cable is approved for use in vertical shafts and large facilities with mulitple levels for critical circuits such as fire alarms and smoke detectors.

Welding Cable

This cable withstands abrasion, oil, and the rough conditions found in welding applications.

Flame-Resistant Welding Cable

Approved for flame resistance, this cable meets Mine Safety and Health Administration (MSHA) standards. The insulation resists abrasion and chemicals.
