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
