ABSTRACT:
A portable engine generator includes an overcurrent detector which detects load current to determine whether the engine is in an overcurrent state. A voltage detector detects output voltage from the engine generator. A timer circuit starts to operate when the overcurrent state is detected by the overcurrent detector and continues to operate while the overcurrent state continues to be detected. The timer circuit starts to output a signal for interrupting the supply of output power when a predetermined time period has elapsed after the start of operation thereof. The predetermined time period is set to a shorter time period as the output voltage detected by the voltage detector assumes a lower value.
