Which type of outlet is designed for wet locations to prevent electrical shock?

A GFCI outlet, or Ground Fault Circuit Interrupter, is specifically designed to protect against electrical shock in areas where water is present, such as kitchens, bathrooms, and outdoor locations. It functions by continuously monitoring the amount of current flowing through the circuit. If it detects an imbalance, indicating that current is flowing through an unintended path (such as water or a person), it quickly interrupts the circuit, thereby reducing the risk of shock.

In wet locations, the likelihood of electrical shock is significantly higher, so the use of GFCI outlets is a requirement in many electrical codes. They enhance safety more effectively than standard outlets, which do not have this protective mechanism. Additionally, while AFCI outlets are designed to prevent arc faults and reduce the risk of electrical fires, and USB outlets serve to provide power for USB devices, neither is specifically focused on protection against electrical shock in wet conditions.
