Electrical Wiring and Building Definitions

Practice vocabulary flashcards defining standard electrical and construction terminology including structures, busbars, cabinets, and types of cables.

Building

A structure that stands alone or that is separated from adjoining structures by fire walls.

Building, Manufactured

Any building that is of closed construction and is made or assembled in manufacturing facilities on or off the building site for installation, or for assembly and installation on the building site, other than manufactured homes, mobile homes, park trailers, or recreational vehicles.

Bundled

Cables or conductors that are tied, wrapped, taped or otherwise periodically bound together.

Busbar

A noninsulated conductor electrically connected to the source of supply and physically supported on an insulator providing a power rail for connection to utilization equipment such as sensors, actuators, A/V devices, low-voltage luminaires, and similar electrical equipment.

Cabinet

An enclosure that is designed for either surface mounting or flush mounting and is provided with a frame, mal, or trim in which a swinging door or doors are or can be hung.

Cable, Abandoned

Installed cable that is not terminated at equipment other than a termination fitting or a connector and is not identified for future use with a tag.

Cable, Armored (Type AC)

A fabricated assembly of insulated conductors in a flexible interlocked metallic armor.

Cable, Metal Clad (Type MC)

A factory assembly of one or more insulated circuit conductors with or without optical fiber members enclosed in an armor of interlocking metal tape, or a smooth or corrugated metallic sheath.

Cable, Nonmetallic-Sheathed

A factory assembly of two or more insulated conductors enclosed within an overall nonmetallic jacket.

Cable, Nonmetallic-Sheathed (Type NM)

Insulated conductors enclosed within an overall nonmetallic jacket.

Cable, Nonmetallic-Sheathed (Type NMC)

Insulated conductors enclosed within an overall, corrosion resistant, nonmetallic jacket.

Cable, Service

Service conductors made up in the form of a cable.

Cable, Service Entrance (Type SE)

Service entrance cable having a flame-retardant, moisture- resistant covering.

Cable, Service Entrance (Type USE)

Service-entrance cable identified for underground use, having a moisture-resistant covering, but not required to have a flame-retardant covering.

Cable, Underground Feeder and Branch-Circuit (Type UF)

(Underground Feeder and Branch-Circuit Cable) A factory assembl of one or more insulated conductors with an integral or an overall covering of nonmetallic material suitable for direct burial in the earth. (CMP-6)

Cable Bundle

A group of cables that are tied together or in contact with one another in a closely packed configuration for at least $1.0\,m$ ($40\,in.$).

Cable connector

A connector designed to join flat conductor cables (Type FCC) without using a junction box.

Cable Management System

An apparatus designed to control and organize lengths of cable or cord.
