What does GFCI stand for?

The term GFCI stands for Ground Fault Circuit Interrupter. This device is designed to protect people from electric shock by monitoring the electrical current flowing in a circuit. If it detects an imbalance between the outgoing current and the incoming current, which could indicate a leakage of current, the GFCI quickly shuts off the power to prevent potentially lethal shocks. This is especially important in wet locations, such as bathrooms and kitchens, where the risk of electric shock is higher.

Understanding the function and importance of a GFCI is crucial for fire investigation technicians, as it plays a significant role in electrical safety in homes and buildings. Identifying and ensuring that GFCIs are installed and functioning properly can help prevent electrical fires that may arise from faulty wiring or appliances.
