circuit breaker
anything equipment that uses electricity
load
used for connecting two or more wires to a single screw terminal. Also called a jumper
pigtail
common term for electrical conductor
wire
two or more conductors (wires) grouped in a single unit by a protective sheath
Cable
material, usually copper or aluminum, which contains movable electric charges
conductor
safety device that provides over current protection for a circuit
circuit breaker
device that allows plug in access to a circuit
receptacle
device that controls electrical power in a circuit
switch
path through which electrical current flows
Circuit
movement of electrons through an electrical conductor
current
ungrounded conductor that carries the electrical current to the load
hot conductor
panel board that located in the residence which receives electrical power from the power supplier and is the source for branch circuits and their protection
the measure of electrical power as it flows through a conductor
volt or voltage
device that provides protection from arc faults by de-engergizing the circuit when an arc fault's characteristics are detected
Arc fault circuit interrupter (AFCI)
conductor that transmits current to the earth in the event of a short circuit
grounding conductor
device that provides protection against shock from a short circuit
Ground fault circuit interrupter - GFCI
device used for measuring the total current used in a structure
service meter
measurement of the total amount of energy consumed. Obtained by multiplying the voltage by the amperage.
watt or wattage
conductor, white in color, that returns current under zero pressure from the load back to the power source
grounded circuit conductor
conductor that carries only the ampere imbalance between two ungrounded conductors
neutral wire
point in the circuit where current is utilized for receptacles, switches, appliances, lighting, etc.
outlet
panel board for additional branch circuit distribution. Receives power from the SEP
subpanel
opposition to the flow of electrons
resistance
