A Ground Fault Circuit Interrupter (GFCI) is essential in electrical installations, particularly in areas where there is a risk of moisture or water exposure, such as kitchens, bathrooms, and outdoor spaces. The primary function of a GFCI is to continuously monitor the current flowing through the circuit; it will quickly disconnect the power if it detects any imbalance between incoming and outgoing current. This imbalance could indicate a leakage current that may cause electric shock, which substantially increases the risk of injury or fatality in wet environments.

In situations where there is a potential for electric shock, a GFCI provides a vital layer of protection by significantly reducing the likelihood of electrocution. While fuses serve to prevent overcurrent conditions and surge protectors help safeguard against voltage spikes, they do not specifically address the safety hazard posed by ground faults. Similarly, voltage stabilizers are effective in regulating voltage levels but are not designed to interrupt the circuit in case of ground faults. Thus, for comprehensive safety in electrical installations, especially in high-risk areas, the use of a GFCI is highly recommended.
