About Wire and Cable

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

Variable-Frequency Drive 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 PVC Outer Jacket


	With Uninsulated Ground Wire

Cable with power wires sends electricity to run a motor.

Uninsulated Ground Wire—Cable with an uninsulated ground wire has an additional uninsulated ground wire you can use to ground the cable’s foil shielding. Also known as a drain wire, it isn’t counted in the cable’s number of wires.

MSHA Accepted—MSHA-accepted cable meets Mine Safety and Health Administration (MSHA) standards for material quality.

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.
