ACCURATE ANSWERS GRADED APLUS
●● American Wire Gauge (AWG)
Answer: an standard method of denoting the diameter of electrically
conducting wire
●● Bonding
Answer: The process of connecting, both physically and electrically,
metal components of the electrical system that are not intended to carry
electrical current to provide a low resistance return path to the circuit
breaker or fuse to clear ground faults; bonding is an elecsafety system.
system.
●● Branch Circuit
Answer: Conductors that begin at a circuit breaker or fuse and serve one
or more oulets.
●● Branch Circuit, multiwire
Answer: A branch circuit in which two energized conductors share one
neutral, examples can include clothes dryers, ranges and other cooking
appliances, and split-wire receptacle circuits, 240 volt water heaters and
,condensers for air conditioners and heat pumps are not usually branch
circuits.
●● Bus (buss, busbar)
Answer: the heavy, rigid metal part of a panelboard on which circuit
breakers or fuses are mounted; sometimes used to describe metal
terminals to which the neutral and equipment grounding conductors
(EGCs) are connected.
●● Cable
Answer: two or more conductors encased in sheathing; examples include
non-metallic sheathed cable (Brand Romex) and armored cable (Brand
BX)
●● circuit breaker
Answer: overcurrent protection device (OPD)
●● Conductor
Answer: a material, such as copper or aluminum, that permits electricity
to flow with low resistance, wires are conductors.
●● Current
Answer: the amount of electricity in a circuit. Unit of measure is the
ampere (amp); expressed as I in Ohm's Law and Watt's Law equation.
,●● Dead front cover
Answer: a panel that is removed to gain access to the energized
components inside an enclosure; the dead front cover is usually behind a
door that must be swung or lifted to gain access to the dead front cover.
●● EGC
Answer: Equipment grounding conductor
●● Enclosure (electrical)
Answer: a case or cabinet intended to prevent accidental contact with
energized parts, a panelboard is housed inside an enclosure.
●● Feeder conductors
Answer: conductors from the service equipment or from a panelboard
that supply electricity to another panelboard such as a subpanel.
●● Fuse
Answer: Overcurrent protection device (OPD)
●● Grounded
Answer: a conductor that is intentionally connected to earth; this
describes what is often called the neutral conductor.
, ●● grounding
Answer: providing an intentional connection to earth, grounding
provides an alternate path for current to return to its source; in an
electrical power system, the source is the utilities transformer and
ultimately power plant. See grounding electrode and grounding electrode
conductor (GEC).
●● Grounding Conductor, Equipment (EGC)
Answer: a bare or insulated conductor that provides a ground fault
current path (a bonding connection) for equipment with metal cases and
parts; these have been installed in most house branch circuit wiring since
around 1960.
●● grounding electrode
Answer: metal that is in direct contact with the earth and serves as the
electrical system grounding connection; examples include copper coated
steel rods, galvanized steel pipes, water service and well pipes, and
reinforcing steel encased footings.
●● grounding electrode conductor (GEC)
Answer: a conductor that runs between the grounding electrode and an
accessible point downstream from where the grounded service entrance
conductor connects to the service drop or lateral; the GEC connection is
usually at the service equipment.
