What is the purpose of GFCI outlets?

GFCI outlets are specifically designed to protect against ground faults, which occur when there is an unintended path between the source of current and the ground. The GFCI, or Ground Fault Circuit Interrupter, monitors the electrical current flowing through the circuit. If it detects an imbalance between the outgoing and incoming currents, which could indicate a leakage of electricity through an individual (possibly due to contact with water), it will quickly shut off the power to prevent electrical shock or electrocution.

This safety feature is critical in areas where electrical devices might come into contact with water, such as kitchens, bathrooms, and outdoor settings. The primary mission of GFCI outlets is to enhance safety by detecting and interrupting ground faults in real-time, thus minimizing the risk of electrical hazards.
