NFPA 70E Definitions Exam with correctanswers
Accessible (as applied to equipment) - correct answer -Admitting close approach; not guarded by locked
doors, elevation, or other effective means
Accessible (as applied to wiring methods) - correct answer -Capable of being removed or exposed
without damaging the building structure or finish or not permanently closed in by the structure or finish
of the building
Accessible, Readily (Readily Accessible) - correct answer -Capable of being reached quickly for operation,
renewal, or inspections without requiting those to whom ready access is requisite to actions such as to
use tools, to climb over or remove obstacles, or to resort to portable ladders, and so forth
Approved - correct answer -Acceptable to the authority having jurisdiction
Arc Flash Hazard - correct answer -A dangerous condition associated with the possible release of energy
caused by an electric arc
Arc Flash Suit - correct answer -A complete arc-rated clothing and equipment system that covers the
entire body, except for the hands and feet
Arc Rating - correct 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 (EBT)
(should a material system exhibit a breakopen response below the ATPV value). Arc rating is reported as
either ETPV or EBT, whichever is the lower value.
Attachment Plug (Plug Cap) (Plug) - correct 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

energized electrical conductors and circuit parts or to prevent unauthorized access to a work area
Bonded (Bonding) - correct answer -Connected to establish electrical continuity and conductivity
Bonding Conductor or Jumper - correct answer -A reliable conductor to ensure the required electrical
conductivity between metal parts required to be electrically connected
Boundary, Arc Flash - correct answer -When an arc flash hazard exists, an approach limit at a distance
from a prospective arc source within which a person could receive a second degree burn if an electrical
arc flash were to occur
Boundary, Restricted Approach - correct answer -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, for personnel working in close
proximity to the energized electrical conductor or circuit part
Branch Circuit - correct answer -The circuit conductors between the final overcurrent device protecting
the circuit and the outlet(s)
