A portable electric vehicle supply equipment (EVSE) includes a first line and a second line, a current sensor, a microcontroller, and at least one protective relay. The current sensor is connected to monitor at least one of the first line or the second line and a current module is connected to sample the monitored current. The microcontroller is configured to detect arc faults in the first line and/or the second line based on the sampled current and to selectively open the protective relay in response to a detected arc fault.
