    Abstract: A circuit interrupting device including a phase conductor, a neutral conductor, an interrupter configured to disconnect the phase conductor and the neutral conductor from a load, and a sensor configured to generate a signal indicative of current flowing through the phase conductor and the neutral conductor. The circuit interrupting device further includes a microcontroller that includes an electronic processor and is electrically connected to the first sensor and the interrupter. The microcontroller is configured to generate a reference signal, receive a first signal from the sensor, determine whether a difference between a voltage of the first signal and a voltage of the reference signal exceeds a threshold, determine whether the microcontroller has performed a ground fault self-test, and activate the interrupter when the difference exceeds the threshold and the microcontroller has not performed the ground fault self-test.

    Abstract: A circuit interrupting device including a line terminal, a current sensor to measure a current flowing through the line terminal, a zero cross detection circuit to measure a voltage and a frequency of the line terminal, and a microcontroller. The microcontroller configured to apply a digital filter to a line current measurement signal, determine zero cross positions of a line voltage measurement signal, count a plurality of turning points of the filtered line current measurement signal, determine a position of each of the plurality of turning points relative to a corresponding zero cross position, determine a time between each turning point and subsequent turning point, and determine whether an arc fault is present within the circuit interrupting device based on the plurality of turning points, the position of each turning point relative to the corresponding zero cross position, and the time between each turning point and the subsequent turning point.
