The maximum current, in amp years, a conductor can carry can seamlessly, under the conditions of use without exceeding its temperature rating.

Question 6

Arc-fault circuit interrupter (AFCI)

Answer 6

An Arc-fault circuit interrupter it is a device intended to de-energize the circuit when it detects the current unique to an arcing fault.

Question 7

Attachment plug (plug cap) (plug)

Answer 7

A wiring device at the end of a flexible court intended to be inserted into a receptacle in order to make an electrical connection

Question 8

authority having jurisdiction (AHJ)

Answer 8

The organization, office, or individual response for approving equipment, materials, and installation, or a procedure.

Question 9

Bonded (bonding)

Answer 9

Connected to establish electrical continuity and connectivity

Question 10

Bonding conductor or jumper

Answer 10

A conductor that ensures electrical conductivity between metal parts of the electrical installation

Question 11

Bunting jumper, Main

Answer 11

A conductor, screw, or strapped that connects the circuit equipment grounding conductor to the neutral conductor at the Service Equipment in accordance with 250.24(B)

Question 12

Bonding jumper system

Answer 12

The connection between the neutral conductor and the supply side of bonding jumper or equipment ground conductor, and it’s separately to drive system transformer or separately derived system generator

Question 13

Branch circuit

Answer 13

The conductor’s between the final over current protection device and the receptacle outlets, playing outlets, or other outlets as defined in this article

Question 14

Branch circuit

Answer 14

A branch circuit that’s only supplies one load

Question 15

Branch circuit, multi-wire

Answer 15

A branch circuit that consists of two or more ungrounded circuit conductors with a comment neutral conductor. There must be a voltage between the ungrounded conductors and an equal difference of voltage from each ungrounded to the common neutral conductor

Question 16

Building

Answer 16

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

Question 17

Cabinet

Answer 17

An enclosure for either surface mounting or flush mounting provided with a frame in which a door can be hung.

Question 18

Charge controller

Answer 18

Equipment that controls DC voltage or DC current, or both, and is used to charge a batter or other energy storage device

Question 19

Circuit breaker (inverse time)

Answer 19

Inverse time breakers operate on the principle that is the current increases, the time it takes for the device to open decreases. This type of breaker provides overcurrent protection (overload, short circuit, and ground fault). This is the most common type of circuit breaker that you’ll buy over the counter.

Question 20

Circuit Breaker (instantaneous trip)

Answer 20

Instantaneous trip breakers operate on the principle of electromagnetism only and are used for motors. Sometimes these devices are called Motor Circuit Protectors. this type of overcurrent protection device doesn’t provide overload protection. It only provides short-circuit and ground fault protection; overload protection must be provided separately.

Question 21

Combustible dust

Answer 21

Dust particles that are 500 microns or smaller and pose a combustion possibility.

Question 22

Communications equipment

Answer 22

Electronic telecommunications equipment used for the transmission of audio, video, and data, including support equipment such as computers, as well as conductors that are used solely for the operation of the equipment.

Question 23

Communications raceway

Answer 23

An enclosed nonmetal channel designed for holding communications wires and cables.

Question 24

Composite Optical Fiber Cable

Answer 24

a cable containing optical fibers and current carrying electrical conductors

Question 25

Conduit Body

Answer 25

a fitting that’s installed in a conduit or tubing system ad provides access to conductors through a removable cover

Question 26

Pressure Connector

Answer 26

A device that establishes a conductive connection between conductors or between a conductor and a terminal by the means of mechanical pressure.

Question 27

Continuous load

Answer 27

a load where the maximum current is expected to exist for 3 hours or more continuously, such as store, or parking lot lighting.

Question 28

control circuit

Answer 28

the circuit of a control apparatus or system that carries the electric signals directing the performance of the controller buy doesn’t carry the main power current.
