Article conclusion:   “….arc flash hazard analysis now tells us that the setting of protective devices on this basis could be detrimental to operational and maintenance personnel if an arcing fault occurs when the electrical equipment is worked on in the energized state. We must take into account the thermal limits of the human body (onset of second degree burns at 1.2cal/cm2  when selecting protective devices and their settings. Arc flash hazards are an extremely important consideration when designing electrical distribution systems.”
