An apparatus and method for detecting arc faults in a circuit having a switch (28), including a leakage current management device (46), an arc fault detector (30) arranged to monitor output voltage and to send a signal representative of the output voltage, and a controller (36) coupled to the arc fault detector (30). The controller (36) is configured to monitor the output voltage signal, compare the output to a threshold, and if the output exceeds the threshold, provide an arc fault indication.
