Quizplus · Accepted Answer

An arc-fault circuit interrupter (AFCI) is a device that is designed to provide protection from the effects of arc faults by recognizing characteristics unique to arcing. It works by detecting unintentional electrical arcing and disconnecting the power before it can start a fire. A circuit interrupter (CI) and grounded circuit interrupter (GCI) are not specifically designed to detect arc faults. A diagnostic arc-fault interrupter (DACI) is not a commonly used term in the electrical industry.
