A GFCI mis-wiring detector includes a set of input terminals for an AC source, and a set of output terminals for an AC load. The set of output terminals are conductively connected to the set of input terminals. A GFCI circuit has one or more switches that selectively interrupt the connection between the set of input terminals and the set of output terminals when a ground fault occurs. A mis-wiring detection circuit causes the one or more switches of the GFCI circuit to open when the AC source is electrically coupled to the set of output terminals for a first time interval, even if there is no imbalance in the current flow. Additionally, a suppression circuit suppresses operation of the mis-wiring detection circuit when the AC source is electrically coupled to the input terminals for a second time interval. The second time interval is less than the first time interval.
