Electrical cable

An electrical cable is an assembly of one or more wires running side by side or bundled, which is used to carry electric current. A cable assembly is the composition of one or more electrical cables and their corresponding connectors. Cable assemblies can also take the form of a cable tree or cable harness , used to connect many terminals together. The term cable originally referred to a nautical line of specific length where multiple ropes are combined to produce a strong thick line that was used to anchor large ships. As electric technology developed, people changed from using bare copper wire to using groupings of wires and various sheathing and shackling methods that resembled the mechanical cabling so the term was adopted for electrical wiring.

The term "electrical conduit" refers to durable tubing or other types of enclosure used to protect and provide a route for individual electrical wiring conductors. Conduit is typically required where wiring is exposed or where it might be subject to damage. A conduit can be made of metal or plastic and may be rigid or flexible. All conduit is installed with compatible fittings couplings, elbows, connectors and electrical boxes, usually made of the same or similar material. There are seven different types of conduit used commonly in residential and light commercial wiring. Rigid metal conduit, or RMC, is heavy-duty galvanized steel tubing that is installed with threaded fittings. It is typically used outdoors to provide protection from damage and can also provide structural support for electrical cables, panels, and other equipment.
