QUESTIONS AND ANSWERS
Bonding Jumper (Equipment) - ANSWER-The connection between two or more portions
of the equipment grounding conductor.
Bonding Jumper, Main - ANSWER-The connection between the grounded circuit
conductor and the equipment grounding conductor at the service.
Bonding Jumper, Supply-Side - ANSWER-A conductor installed on the supply side of a
service or within a service equipment enclosure(s) that ensures the required electrical
conductivity between metal parts required to be electrically connected.
Branch Circuit - ANSWER-The circuit conductors between the final overcurrent device
protecting the circuit and the outlet(s).
Branch Circuit, Appliance - ANSWER-A branch circuit that supplies energy to one or
more outlets to which appliances are to be connected and that has no permanently
connected luminaires that are not a part of an appliance.
Branch Circuit, Individual - ANSWER-A branch circuit that supplies only one utilization
equipment.
Branch Circuit, Multiwire - ANSWER-A branch circuit that consists of two or more
ungrounded conductors that have a voltage between them, and a grounded conductor
that has equal voltage between it and each ungrounded conductor of the circuit and that
is connected to the neutral or grounded conductor of the system.
Cabinet - ANSWER-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.
Circuit Breaker - ANSWER-A device designed to open and close a circuit by
nonautomatic means and to open the circuit automatically on a predetermined
overcurrent without damage to itself when properly applied within its rating.
Clothes Closet - ANSWER-A non-habitable room or space intended primarily for
storage of garments and apparel.
Concealed - ANSWER-Rendered inaccessible by the structure or finish of the building.
, Conductor, Bare - ANSWER-A conductor having no covering or electrical insulation
whatsoever.
Accessible (As applied to equipment.) - ANSWER-Admitting close approach as a result
of not being guarded by locked doors, elevation or other effective means
Accessible (As applied to wiring methods.) - ANSWER-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.
Accessible, Readily - ANSWER-Capable of being reached quickly for operation,
renewal or inspections, without requiring those to whom ready access is requisite to
take actions such as to use tools, other than keys, to climb over or remove obstacles or
to resort to portable ladders, and so forth.
Ampacity - ANSWER-The maximum current in amperes that a conductor can carry
continuously under the conditions of use without exceeding its temperature rating.
Appliance - ANSWER-Utilization equipment, normally built in standardized sizes or
types that is installed or connected as a unit to perform one or more functions such as
clothes washing, air conditioning, food mixing, deep frying, etc.
Approved - ANSWER-Acceptable to the authority having jurisdiction.
Arc-Fault Circuit Interrupter (AFCI) - ANSWER-A device intended to provide protection
from the effects of arc faults by recognizing characteristics unique to arcing and by
functioning to de-energize the circuit when an arc fault is detected.
Attachment Plug (Plug Cap) (Plug) - ANSWER-A device that, by insertion in a
receptacle, establishes a connection between the conductors of the attached flexible
cord and the conductors connected permanently to the receptacle.
Automatic - ANSWER-Performing a function without the necessity of human
intervention.
Bathroom - ANSWER-An area including a basin with one or more of the following: a
toilet, a urinal, a tub, a shower, a bidet, or similar plumbing fixtures.
Bonded (Bonding) - ANSWER-Connected to establish electrical continuity and
conductivity.
Bonding Conductor or Jumper - ANSWER-A reliable conductor to ensure the required
electrical conductivity between metal parts required to be electrically connected.
Conductor, Covered - ANSWER-A conductor encased within material of composition or
thickness that is not recognized by this Code as electrical insulation.
