A GFCI (Ground Fault Circuit Interrupter) outlet is specifically designed to prevent electrical shock, particularly in wet areas where the risk of such incidents is heightened, like bathrooms, kitchens, and outdoor locations. The GFCI monitors the flow of electricity and can detect imbalances between the outgoing and incoming electrical currents. If it senses that some of the current is escaping to the ground, which often indicates a fault such as a person coming into contact with a live wire, the GFCI outlet will quickly cut off the power to prevent serious injury or fatality from electric shock. This safety feature is crucial in environments where moisture is present, as water can increase the likelihood of electrical shocks.
