Texas RAIL Exam Questions and
Answers
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, 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 - Answer-Acceptable to the authority having jurisdiction.
Authority Having Jurisdiction - 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.
Attachment 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.
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 - Answer-Connected to establish electrical continuity and conductivity.
Bonding Jumper - Answer-A reliable conductor to ensure 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).
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.
Concealed - Answer-Rendered inaccessible by the structure or finish of the building.
Bare Conductor - Answer-A conductor having no covering or electrical insulation
whatsoever.
Covered Conductor - Answer-A conductor encased within material of composition or
thickness that is not recognized by this code as electrical insulation.
, Insulated Conductor - Answer-A conductor encased within material of composition and
thickness that is recognized by this Code as electrical insulation.
Conduit Body - Answer-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 - Answer-A load where the maximum current is expected to continue
for 3 hours or more.
Continuous Duty - Answer-Operation at a substantially constant load for an indefinitely
long time.
Dead Front - Answer-Without live parts exposed to a person on the operating side of the
equipment.
Feeder - Answer-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 - Answer-The earth
Grounded - Answer-Connected (connecting) to ground or to a conductive body that
extends the ground connection.
GFCI - Answer-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 - Answer-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 - Answer-A conducting object through which a direct connection to
earth is established.
In Sight From - Answer-Where this Code specifies that one equipment shall be "in sight
from," "within sight from," or "within sight," and so forth, of another equipment, the
specified equipment is to be visible and not more than 15 m distant from the other.
Listed - Answer-Equipment, materials, or services included in a list published by an
organization that is acceptable to the authority having jurisdiction and concerned with
evaluation of products or services, that maintains periodic inspection of production of
listed equipment or materials or periodic evaluation of services, and whose listing states
