NFPA 70E Exam Questions and
Answers 100% Pass
Arrangement of 70E - ANSWER-Introduction (Article 90)
Chapter 1 Safety Related Work Practices
Chapter 2 Safety Related Maintenance Requirements
Chapter 3 Safety Requirements for Special Equipment
Annexes (Article 350)
Arc Flash Hazard - ANSWER-A dangerous condition associated with the possible
release of energy caused by an electric arc
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.
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 or to prevent
unauthorized access to a work area.
Shock boundaries - ANSWER-Limited approach boundary,
Restricted approach boundary,
Prohibited approach boundary (not in 2015)
Limited approach boundary - ANSWER-An approach limit at a distance from an
exposed energized electrical conductor or circtuit part within which a shock hazard
exists.
Restricted approach boundary - 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.
Arc Flash Boundary - 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.
Electrically safe work condition - ANSWER-A state in which an electrical
conductor or circuit part has been disconnected from energized parts,
