What does the acronym "GFCI" stand for, and what is its purpose?

The acronym "GFCI" stands for Ground Fault Circuit Interrupter. Its primary purpose is to protect individuals from electrical shock. A GFCI is a safety device commonly used in areas where water and electricity may come into contact, such as kitchens, bathrooms, and outdoor spaces. It functions by continuously monitoring the flow of electrical current through a circuit. If it detects an imbalance between the outgoing and incoming current — which may indicate a leakage of current to the ground, potentially through a person’s body — it interrupts the flow of electricity almost instantaneously. This rapid response can prevent severe shocks, injuries, or fatalities caused by electrical current.

Understanding the importance of GFCIs in safety protocols helps emphasize their role in reducing the risk of accidents related to electricity.
