JATC Definitions Test 2024 updated
correctly answered to pass
Ampacity - correct answer ✔✔The maximum current, in amperes, that a conductor can carry
continuously under the conditions of use without exceeding its temperature rating.
Appliance - correct answer ✔✔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.
Appliance Branch Circuit - correct 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 luminaries that
are not a part of an appliance.
Approved - correct answer ✔✔Acceptable to the authority having jurisdiction.
Arc-Fault Circuit Interrupter (AFCI) - correct 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.
Authority Having Jurisdiction (AHJ) - correct answer ✔✔An organization, office, or individual responsible
for enforcing the requirements of a code or standard, or for approving equipment, materials, an
installation, or a procedure.
Bonded - correct answer ✔✔Connected to establish electrical continuity and conductivity.
Bonding Jumper - correct answer ✔✔A reliable conductor to ensure the required electrical conductivity
between metal parts required to be electricalky connected.
Bonding Jumper, Equipment - correct answer ✔✔The connection between two or more portions of the
equipment grounding conductor.
, Bonding Jumper, Main - correct answer ✔✔The connection between the grounded circuit conductor and
the equipment grounding conductor, or the supply side bonding jumper, or both, at the service.
Bonding Jumper, System - correct answer ✔✔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.
Bonding Jumper, Supply Side - correct answer ✔✔A conductor installed on the supply side of a service or
within a service equipment enclosure(s), or for a separately derived system, that ensures the required
electrical conductivity between metal parts required to be electrically connected.
Branch Circuit - correct answer ✔✔The circuit conductors between the final overcurrent device
protecting the circuit and the outlet(s).
Building - correct answer ✔✔A structure that stands alone or that is separated from adjoining structures
by fire walls.
Cabinet - correct answer ✔✔An enclosure that is designed for either surface mounting or flush
mounting and is provided with a frame, may, or trim in which a swinging door or doors are or can be
hung.
Circuit Breaker - correct 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.
Concealed - correct answer ✔✔Rendered inaccessible by the structure or finish of the building.
Continuous Duty - correct answer ✔✔Operation at a substantially constant load for an indefinitely long
time.
Continuous Load - correct answer ✔✔A load where the maximum current is expected to continue for 3
hours or more.
