The present disclosure provides an industrial GFCI for control panels and/or industrial machines. The industrial GFCI senses when a fault condition has occurred in an associated circuit or load and quickly disconnect the circuit. In some exemplary embodiments, the industrial GFCI includes a bypass switch, which couples a load directly to a power source, bypassing fault detection. In some exemplary embodiments, the industrial GFCI also includes intelligent filtering, which discriminate between true fault events and false signals caused by environmental noise. Further, the industrial GFCI is manufactured as a part of a control panel or a piece of equipment. In certain exemplary embodiments, the industrial GFCI is manufactured as a portable kit capable of coupling to and decoupling from one or more control panels, machines, etc.
