Claim 2:
3. 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; 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 a steady-state condition, wherein a steady-state of the current exists when the one or more cycles of current conform to both a range of allowable variation in RMS value and an envelope of acceptable variation in correlation coefficient value, and
prevent the tripped condition upon identifying the steady-state condition.
