NFPA 70E Final Test Questions and
Answers | Examination Preparation
Guide | Graded A+
‣ Approved -✓✓Admitting close approach; not guarded by locked doors,
elevation or other effective means.
‣ Arc Flash Suit -✓✓A complete arc-rated clothing and equipment
system that covers the entire body, except for the hands and feet.
‣ Arc Rating -✓✓The value attributed to materials that describes their
performance to exposure to an electrical arc discharge. The arc rating is
expressed in cal/cm^2 and is derived from the determined value of the
arc thermal performance value (ATPV) or energy of breakopen
threshold (E BT) (should a material system exhibit a breakopen
resoponce below the APTV value). Arc rating is reported as either
APTV or E bt, whichever is the lower value.
‣ Attachment Plug (Plug Cap or Plug) -✓✓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.
‣ Authority Having Jurisdiction (AHJ) -✓✓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.
‣ Authorized Personnel -✓✓The person in charge of the premises, or
other persons appointed or selected by the person in charge of the
premises who performs certain duties associated with stationary storage
batteries.
‣ Automatic -✓✓Performing a function without the necessity of human
intervention.
‣ Balaclava -✓✓An arc-rated head protective fabric that protects the
neck and head except for a small portion of the facial area
‣ Barricade -✓✓A physical obstruction such as tapes, cones or A-frame-
type wood or metal structures intended to provide a warning and to limit
access.
‣ Barrier -✓✓A physical obstruction that is intended to prevent contact
with equipment or energized electrical conductors and circuit parts.
‣ Battery -✓✓A system consisting of two or more electrochemical cells
connected in series or parallel and capable of storing electrical energy
received and that can give it back by reconversion.
, ‣ Battery Effect -✓✓A voltage that exists on the electrolytic cell line
after the power supply is disconnected
‣ Battery Room -✓✓A room specifically intended for the installation of
batteries that have no other protective enclosure
‣ Bonded (Bonding) -✓✓Connected to establish electrical continuity and
conductivity.
‣ Bonding Conductor or Jumper -✓✓A reliable conductor to ensure the
required electrical conductivity between metal parts required to be
electrically connected.
‣ Boundary, Arc Flash -✓✓When an arc flash hazard exists, an approach
limit from an arc source at which incident energy equals 1.2 cal/cm^2
(5J/cm^2)
‣ Boundary, Hearing Protection -✓✓Worker distance at which a 1
percent probability of ear damage exists from a 20 kPa (3.0 psi)
shockwave.
‣ Boundary, Limited Approach -✓✓An approach limit at a distance from
an exposed energized electrical conductor or circuit part within which a
shock hazard exists.
