What is the primary purpose of a Ground Fault Circuit Interrupter (GFCI)?

The primary purpose of a Ground Fault Circuit Interrupter (GFCI) is to protect against electric shock in damp and wet conditions. GFCIs monitor the electrical current flowing through a circuit and can detect imbalances that may indicate a ground fault or leakage of current, which typically occurs when electricity finds an unintended path to the ground. This is particularly crucial in areas such as bathrooms, kitchens, and outdoor settings where moisture is present and increases the risk of shock. When a ground fault is detected, the GFCI quickly interrupts the circuit, thereby minimizing the chance of serious injury or fatality due to electric shock.

This safety device is essential in maintaining safe electrical practices in environments that pose higher risks due to humidity or water exposure, ensuring protection for individuals who may come into contact with electrical devices under these conditions.
