A wiring device comprising: an interrupting device electrically connecting one or more line terminals to one or more load terminals when the interrupting device is in a reset condition and disconnecting the line terminals from the load terminals when the interrupting device is in a tripped condition; a fault detection circuit configured to detect a fault condition and generate a fault detection signal in response to detecting the fault condition, the fault detection signal being provided to the interrupting device to place the interrupting device in the tripped condition; and a controller having an electronic processor and a memory, the controller configured to monitor a current of the one or more line terminals, identify a presence of at least one selected from a group consisting of a steady-state condition and an in-rush condition, and controlling the fault detection circuit based on identification of at least one selected from the group consisting of the steady-state condition and the -in rush condition characterized in that the in-rush condition exists when the one or more cycles of current conform with a decay progression envelope, and wherein the steady-state condition exists when the one or more cycles of current conform to both a range of allowable variation in a root-mean square, RMS, value and an envelope of acceptable variation in a correlation coefficient value. an interrupting device electrically connecting one or more line terminals to one or more load terminals when the interrupting device is in a reset condition and disconnecting the line terminals from the load terminals when the interrupting device is in a tripped condition; a fault detection circuit configured to detect a fault condition and generate a fault detection signal in response to detecting the fault condition, the fault detection signal being provided to the interrupting device to place the interrupting device in the tripped condition; and a controller having an electronic processor and a memory, the controller configured to monitor a current of the one or more line terminals, identify a presence of at least one selected from a group consisting of a steady-state condition and an in-rush condition, and controlling the fault detection circuit based on identification of at least one selected from the group consisting of the steady-state condition and the -in rush condition characterized in that the in-rush condition exists when the one or more cycles of current conform with a decay progression envelope, and wherein the steady-state condition exists when the one or more cycles of current conform to both a range of allowable variation in a root-mean square, RMS, value and an envelope of acceptable variation in a correlation coefficient value. monitor a current of the one or more line terminals, identify a presence of at least one selected from a group consisting of a steady-state condition and an in-rush condition, and controlling the fault detection circuit based on identification of at least one selected from the group consisting of the steady-state condition and the -in rush condition characterized in that the in-rush condition exists when the one or more cycles of current conform with a decay progression envelope, and
