Arc-fault circuit interrupter : The arc generated due to poor contact of the contact or damage to the insulation ofthe circuit is called a "bad arc"corresponding to a "good arc" .The arc generated by normal operation of the switch is called a "good arc".That is to say, "bad arcs" can do badthings and cause fire hazards. f not dealt with in a timely manner, "bad arcs"can cause significant economic losses and even casualties.
