| Already Rated A+
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
