Understanding what trips a GFCI outlet is essential for any homeowner or DIY enthusiast, as these interruptions are a direct indicator of a potentially dangerous electrical condition. Inside the receptacle, a sensor monitors the electrical current on the hot and neutral wires.

Tools with worn cords, damaged motors, or internal shorts can cause temporary leakage current that the GFCI detects. Over time, the insulation on wires can degrade, leading to minor arcing or capacitance leakage that accumulates and eventually trips the GFCI.
Under normal conditions, these currents should be identical; however, if some of the current takes an unintended path—such as through a person who has touched a faulty appliance—the currents become unbalanced. If your outdoor outlet trips during or after a storm, it might be due to water ingress into the receptacle or connected junction box.
