, ◉ Equipotential Zone. Answer: A(n) - is an area in which all
conductive elements are bonded or other wise connected together in
a manner that prevents a difference of potential from developing
within the area.
◉ Arc Flash. Answer: The - boundary is the distance from exposed
energized conductors or circuit parts where a person would receive
the onset of second degree burns on bare, unprotected skin.
