specific purpose, environment or application may be determined by a nationally recognized

testing laboratory, inspection agency or other organization concerned with product evaluation

as part of its listing and labeling program. (See "Labeled" or "Listed.")

Armored cable--Type AC armored cable is a fabricated assembly of insulated conductors in a

flexible metallic enclosure.

Askarel--A generic term for a group of nonflammable synthetic chlorinated hydrocarbons used

as electrical insulating media. Askarels of various compositional types are used. Under arcing

conditions the gases produced, while consisting predominantly of noncombustible hydrogen

chloride, can include varying amounts of combustible gases depending upon the askarel type.

Attachment plug (Plug cap)(Cap)--A device which, by insertion in a receptacle, establishes

connection between the conductors of the attached flexible cord and the conductors connected

permanently to the receptacle.

Automatic--Self-acting, operating by its own mechanism when actuated by some impersonal

influence, as, for example, a change in current strength, pressure, temperature, or mechanical

configuration.

Bare conductor--See "Conductor."

Bonding--The permanent joining of metallic parts to form an electrically conductive path which

will assure electrical continuity and the capacity to conduct safely any current likely to be

imposed.

Bonding jumper--A reliable conductor to assure the required electrical conductivity between

metal parts required to be electrically connected.

Branch circuit--The circuit conductors between the final overcurrent device protecting the

circuit and the outlet(s).

Building--A structure which stands alone or which is cut off from adjoining structures by fire

walls with all openings therein protected by approved fire doors.

Cabinet--An enclosure designed either for surface or flush mounting, and provided with a

frame, mat, or trim in which a swinging door or doors are or may be hung.

Cable tray system--A cable tray system is a unit or assembly of units or sections, and

associated fittings, made of metal or other noncombustible materials forming a rigid structural

system used to support cables. Cable tray systems include ladders, troughs, channels, solid

bottom trays, and other similar structures.

Cablebus--Cablebus is an approved assembly of insulated conductors with fittings and

conductor terminations in a completely enclosed, ventilated, protective metal housing.

Center pivot irrigation machine--A center pivot irrigation machine is a multi-motored irrigation

machine which revolves around a central pivot and employs alignment switches or similar

devices to control individual motors.
