What type of breaker is designed to prevent electrical shock?

The Ground Fault Circuit Interrupter (GFCI) is specifically designed to protect against electrical shock. It accomplishes this by monitoring the current flowing through a circuit and can quickly detect any imbalance, which typically occurs when electricity is flowing through an unintended path, such as a person who is touching a live electrical source. When such a fault is detected, the GFCI instantly interrupts the electrical flow, greatly reducing the risk of severe injury or fatality due to electric shock.

GFCIs are commonly found in areas where water and electricity are in close proximity, such as kitchens, bathrooms, and outdoor outlets, because these environments pose a higher risk of shock. By providing this critical function, GFCIs play a vital role in electrical safety standards.
