COMPLETE QUESTIONS AND CORRECT
ANSWERS
◉ Approved. Answer: Admitting close approach; not guarded by locked
doors, elevation or other effective means.
◉ Arc Flash Suit. Answer: A complete arc-rated clothing and equipment
system that covers the entire body, except for the hands and feet.
◉ Arc Rating. Answer: 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). 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.
,◉ Authority Having Jurisdiction (AHJ). 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.
◉ Authorized Personnel. Answer: 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. Answer: Performing a function without the necessity of
human intervention.
◉ Balaclava. Answer: An arc-rated head protective fabric that protects
the neck and head except for a small portion of the facial area
◉ Barricade. Answer: 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. Answer: A physical obstruction that is intended to prevent
contact with equipment or energized electrical conductors and circuit
parts.
, ◉ Battery. Answer: 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. Answer: A voltage that exists on the electrolytic cell
line after the power supply is disconnected
◉ Battery Room. Answer: A room specifically intended for the
installation of batteries that have no other protective enclosure
◉ Bonded (Bonding). Answer: Connected to establish electrical
continuity and conductivity.
◉ Bonding Conductor or Jumper. Answer: A reliable conductor to
ensure the required electrical conductivity between metal parts required
to be electrically connected.
◉ Boundary, Arc Flash. Answer: 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. Answer: Worker distance at which a 1
percent probability of ear damage exists from a 20 kPa (3.0 psi)
shockwave.
