ELECTRICAL JATC CODE DEFINITIONS EXAM QUESTIONS ANSWERED CORRECTLY GRADED
A+
Ampacity - Answers The maximum current in amprees that a conductor can carry continuously
under the conditions of use without exceeding its temperature rating
Appliance - Answers Utilization equipment, generally other than industrial, that is normally built
in standardize sizes or types and it's 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
Appliance branch circuit - Answers 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
Approved - Answers Acceptable to the authority having jurisdiction
Arc-fault circuit interrupter - Answers A device intended to provide protection from the effects of
arc fault by recognizing characteristics unique to arcing and by functioning to De-energize the
circuit when the fault is detected
Authority having jurisdiction (AHJ) - Answers An organization, office, or individual responsible
for enforcing the requirements of the code or standard, or for approving equipment, materials,
and installation or procedure
Bonded (bonding) - Answers Connected to establish electrical continuity and conductivity
Bonding jumper, equipment - Answers The connection between two or more portions of
equipment grounding conductor
Bonding jumper, main - Answers The connection between the grounded circuit conductor and
thr equipment grounding conductor At the service
Bonding jumper, system - Answers 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
Branch circuit - Answers The circuit conductors between the final overcurrent device protecting
the circuit and the outlet
Building - Answers A structure that stands alone or that is cut off from ajoining structures by
firewalls with all openings therein protected by approved fire doors
Cabinet - Answers And enclosure that is designed for either surface mount or flush mounting
and is provided with a frame mat or trim and which a swingingdoor or doors are or can be hung
Circuit breaker - Answers Hey device designed to open and close a circuit by non-automatic
means and open the circuit automatically on a predetermined overcurrent without damage to
, itself when properly applied within its rating
Concealed - Answers Rendered inaccessible by the structure or the finish of the building
Continuous duty - Answers Operation at a substantially constant load for ideffentially long time
Continuous load - Answers A load were maximum current is expected to last 3 hours or more
Controller - Answers A device or group of devices that serves to govern, in some pre-determined
manner, the electric power delivered to the apparatus to which it is connected
Covered conductor - Answers A conductor encased within material of composition
Cutout box - Answers And enclosure designed for surface mounting that has swinging doors or
covers secured directly to and telescoping with the walls of the enclosure
Damp location - Answers Locations protected from weather and not subject to saturation with
water or other liquids but subject to moderate degrees of moisture
Dead front - Answers Without live parts exposed to a person on the operating side of the
equipment
Device - Answers A unit of an electrical system other than a conductor that carries or controls
electrical energy as its primary function
Disconnecting means - Answers Device or group of devices or other means by which the
conductors of a circuit can be disconnected from their source of supply
Dry location - Answers They location not normally subject to dampness or wetness a location
classified as dry maybe temporarily subject to dampness or wetness as in the case of a building
under construction
Dusttight - Answers Enclosure constructed so that dust will not enter under specified task
conditions
Dwelling unit - Answers A single unit providing complete an independent living facilities for one
or more persons including permanent provisions for living sleeping cooking and sanitation
Effective ground fault current path - Answers In intentionally constructed low-impedance
electrically conductive path designed and intended to carry current under ground-fault
conditions from the point of a ground fault on a wiring system to the electrical supply source
and that facilitates the operation of the overcurrent protective device or ground-fault detectors
Enclosed - Answers Surrounded by a case housing fence or walls that prevent persons from
accidentally contacting energized parts
Enclosure - Answers The case or housing of an apparatus or the fence or wall surrounding and
