Which electrical device is designed to prevent electric shock in wet areas?

The Ground Fault Circuit Interrupter (GFCI) is specifically designed to prevent electric shock in wet areas by continuously monitoring the flow of electricity in a circuit. If it detects an imbalance in the electrical current—such as when electricity is flowing through water or a person—it will quickly cut off the power to the circuit, significantly reducing the risk of electric shock.

GFCIs are typically used in locations where water and electricity may come into contact, such as bathrooms, kitchens, and outdoor areas. This safety feature is crucial, as water is a conductor of electricity, and any electric fault in these environments can lead to serious injuries or fatalities.

In contrast, devices like circuit breakers and fuses primarily serve to prevent overloads and short circuits; they do not specifically target the inherent hazards presented by moisture. An Arc-Fault Circuit Interrupter (AFCI) addresses the risk of electrical fires caused by arcing faults but does not provide the same level of protection against electric shock in wet conditions as a GFCI does.
