NFPA 70E Exam | Newest Questions and
Answers | Updated 2026 | Complete
Review
• Accessible (as applied to equipment) -✓✓ Admitting close approach; not
guarded by locked doors, elevation, or other effective means.
• 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.
• Boundary, Lung Protection -✓✓ Worker distance at which 1 percent probability
of lung damage exists from a 70kPa (10psi) shock wave.
• Boundary, Restricted Approach -✓✓ An approach limit at a distance from an
exposed energized electrical conductor or circuit part within which there is an
increased likelihood of electric shock, due to electrical arc-over combined with
inadvertent movement.
• Building -✓✓ A structure that stands alone or that is cut off from adjoining
structures by fire walls with all openings therein protected by approved fire
doors.
