EXAM QUESTIONS AND ANSWERS
Capable of being reached quickly for operation, renewal, or inspections without
requiring those to whom ready access is requisite to actions such as to use tools, to
climb over or remove obstacles, or to resort to portable ladders, and so forth. - Correct
Answers -Accessible, Readily (Readily Accessible)
The maximum current, in amperes, that a conductor can carry continuously under the
conditions or use without exceeding its temperature rating. - Correct Answers -Ampacity
Utilization equipment, generally other than industrial, that is normally built in
standardized sizes or types and is installed or connected as a unit to perform one or
more functions such as clothes washing, air-conditioning, food mixing, deep frying and
so forth. - Correct Answers -Appliance
Acceptable to the authority
having jurisdiction. - Correct Answers -Approved
A device intended to provide protection from the effects of arc faults by reorganizing
characteristics unique to arcing and by functioning to de-energize the circuit when an
arc fault is detected. - Correct Answers -Arc-Fault Circuit Interrupter (AFCI)
An organization, office, or individual responsible for enforcing the requirements of a
code or standard, or for approving equipment, materials, an installation, or procedure. -
Correct Answers -Authority Having Jurisdiction (AH)
Connected to establish continuity and conductivity. - Correct Answers -Bonded
(Bonding)
The connection between two or more portions of the equipment grounding conductor. -
Correct Answers -Bonding Jumper, Equipment
The connection between the grounded circuit conductor and the equipment grounding
conductor at service. - Correct Answers -Bonding Jumper, Main
The connection between the grounded circuit conductor and the supply-side bonding
jumper, or the equipment grounding conductor, or both, at a separately derived system.
- Correct Answers -Bonding Jumper, System
, The circuit conductors between the final overcurrent device protecting the circuit and the
other(s). - Correct Answers -Branch Circuit
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. - Correct Answers -Branch Circuit, Appliance
A branch circuit that supplies two or more receptacles or outlets for lighting and
appliances. - Correct Answers -Branch Circuit, General-Purpose
A branch circuit that supplies only one utilization equipment. - Correct Answers -Branch
Circuit, Individual
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. - Correct Answers -Branch Circuit, Multiwire
A structure that stands alone or that is cut off from adjoining structures by fire walls with
all openings therein protected by approved fire doors. - Correct Answers -Building
An enclosure that is designed for either surface mounting or flush mounting and is
provided with a frame, mat, or trim in which a swinging door or doors are or can be
hung. - Correct Answers -Cabinet
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. - Correct Answers -Circuit Breaker
Instantaneous trip (as applied to circuit breakers) - Correct Answers -A qualifying term
indicating that no delay is purposely introduced in the tripping action of the circuit
breaker
Inverse time (as applied to circuit breakers) - Correct Answers -
Rendered inaccessible by the structure or finish of the building. - Correct Answers -
Concealed
A conductor encased within material of composition or thickness that is not recognized
by this code as electrical insulation. - Correct Answers -Conductor, Covered
A conductor encased within material of composition and thickness that is recognized by
this code as electrical insulation. - Correct Answers -Conductor, Insulated
