Electrical Terms Flashcards

Capable of being removed or exposed without damaging the building structure or finish or not permanently closed in by the structure or finish of the building.

Electrical meter used to measure current, calibrated in amperes.

Measurement of electrical current in a circuit at any given time.

Current-carrying capacity of electric conductors expressed in amperes.

Unit of electric current equivalent to 6.28 quintillion electrons passing a given point in 1 sec.

Flow of electricity through electrical wire.

Tester that is designed to determine running currents, overloads, and balanced circuits.

Two or more insulated wires wrapped in a metal sheathing.

Permanent joining of metallic parts to form an electrically conductive path to ensure electrical continuity and capacity to safely conduct any current likely to be imposed.

Reliable conductor to ensure the required electrical conductivity between metal parts required to be electrically connected.

Metal or plastic enclosure within which electrical connections are made; used for splitting circuits and connecting switches, receptacles, or fixtures; also referred to as a J-box or Junction box.

Circuit conductors between the final overcurrent device protecting the circuit and outlets.

Branch circuit supplying energy to one or more outlets to which appliances are connected. Such circuits have no permanently connected lighting fixtures not part of an appliance.

Branch circuit that supplies many outlets for lighting and appliances.

Main power terminal to which circuits are attached through either fuses or circuit breakers. One bus bar serves the hot side; the other serves the neutral side.
