Abstract:
A wiring device including an interrupting device and a controller. The 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. The controller has an electronic processor and a memory. The controller is configured to monitor a current of the one or more line terminals, identify a presence of an in-rush condition, wherein an in-rush of the current exists when the one or more cycles of current conform with a decay progression envelope, and prevent the tripped condition upon identifying the in-rush condition.
