TEXAS RAIL EXAM QUESTIONS WITH
ACCURATE ANSWERS
Ampacity - Accurate answers The maximum current, in amperes, that a conductor can
carry continuously under the conditions of use without exceeding its temperature rating.
Appliance - Accurate answers 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.
Approved - Accurate answers Acceptable to the authority having jurisdiction.
Authority Having Jurisdiction - Accurate answers 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.
Attachment Plug - Accurate answers 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.
Bathroom - Accurate answers 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 - Accurate answers Connected to establish electrical continuity and conductivity.
Bonding Jumper - Accurate answers A reliable conductor to ensure the required electrical
conductivity between metal parts required to be electrically connected.
Branch Circuit - Accurate answers The circuit conductors between the final overcurrent
device protecting the circuit and the outlet(s).
Circuit Breaker - Accurate answers 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 - Accurate answers Rendered inaccessible by the structure or finish of the
building.
, Bare Conductor - Accurate answers A conductor having no covering or electrical insulation
whatsoever.
Covered Conductor - Accurate answers A conductor encased within material of
composition or thickness that is not recognized by this code as electrical insulation.
Insulated Conductor - Accurate answers A conductor encased within material of
composition and thickness that is recognized by this Code as electrical insulation.
Conduit Body - Accurate answers A separate portion of a conduit or tubing system that
provides access through a removable cover(s) to the interior of the system at a junction of two
or more sections of the system or at a terminal point of the system. Boxes such as FS and FD or
larger cast or sheet metal boxes are not classified as conduit bodies.
Continuous Load - Accurate answers A load where the maximum current is expected to
continue for 3 hours or more.
Continuous Duty - Accurate answers Operation at a substantially constant load for an
indefinitely long time.
Dead Front - Accurate answers Without live parts exposed to a person on the operating
side of the equipment.
Feeder - Accurate answers All circuit conductors between the service equipment, the
source of a separately derived system, or other power supply source and the final branch-
circuit overcurrent device.
Ground - Accurate answers The earth
Grounded - Accurate answers Connected (connecting) to ground or to a conductive body
that extends the ground connection.
GFCI - Accurate answers A device intended for the protection of personnel that functions
to de-energize a circuit or portion thereof within an established period of time when a current
to ground exceeds the values established for a Class A device.
Ground Fault Current Path - Accurate answers An electrically conductive path from the
point of a ground fault on a wiring system through normally non-current-carrying conductors,
equipment, or the earth to the electrical supply source.
Grounding Electrode - Accurate answers A conducting object through which a direct
connection to earth is established.
