The Book of Terms The WJI Book of Wire & Cable Terms: an interactive experience of learning and sharing
This book, written by industry volunteers and containing more than 5,000 entries, is an asset for newcomers to wire and cable.

At the same time, it also represents an opportunity for industry veterans to give back by either updating or adding to the more than 5,000 entries. This is an honor system process. Entries/updates must be non-commercial, and any deemed not to be so will be removed. Share your expertise as part of this legacy project to help those who will follow. Purchase a printed copy here.

Green Vitriol

See Vitriol.

Grinding

The removal of metal from a surface by the application of an abrasive.

Grommet

A rubber seal used to seal cable.

Groove

Slot or cavity in a connector, which bears directly on the cable. Also the depression in a crimping die, which holds the connector during crimping. A depression encircling the body of a roll into which the piece being rolled is forced. Also, a depression on a drum used for winding cables.

Ground

To connect to the earth or other large conducting body to serve as an earth thus making a complete electrical circuit. 2) A wire intended to be used for grounding (also called Grounding Conductor).

Ground Check

A pilot wire in portable cables to monitor the grounding circuit.

Ground Check Conductor

A conductor used in mining cables to monitor the continuity of the grounding circuit which causes the power conductors to be de-energized in the event that ground continuity is lost. Also called a ground-monitoring conductor. Used in types G-GC, SHD-GC and MPF-GC, and identified by yellow colored insulation.

Ground Conductor

A conductor in a transmission cable or line that is grounded.

Ground Fault

See Fault, Ground.

Ground Fault Interrupter

A protective device that detects abnormal current flowing to ground and then interrupts the circuit.

Ground Insulation

The major insulation used between a winding and the magnetic core of other structural parts, usually at ground potential.

Ground Loop

The generation of undesirable current flow within a ground conductor, owing to the circulation currents that originate from a second source of voltage, frequently as a result of connecting two separate grounds to a single circuit.
