Nfpa 70E
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 requiring those to whom ready access is requisite to take actions such as to use tools (other than keys), to climb over or under, to remove obstacles, or to resort to portable ladders, and so forth. Arc Flash Hazard - correct answer A source of possible injury or damage to health associated with the release of energy caused by an electric arc. What elements increase the likelihood of an arc flash incident? - correct answer When energized electrical conductors or circuit parts are exposed or when they are within equipment in a guarded or enclosed condition, provided a person is interacting with the equipment in such a manner that could cause 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. This is expressed in cal/cm2 and is derived from the determined value of the arc thermal performance value or energy of breakopen threshold. How is arc rating reported? - correct answer ATPV (arc thermal performance value) or Ebt (energy of breakopen threshold), whichever is the lower value. Attachment Plug (Plug Cap) - 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. Authority Having Jurisdiction (AHJ) - correct 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. Automatic - correct answer Performing a function without the necessity of human intervention. Balaclava (Sock Hood). - correct answer An arc-rated hood that protects the neck and head except for the facial area of the eyes and nose. Barricade - correct 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 - correct 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. 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 from an arc source at which incident energy equals 1.2 cal/cm2.
