What does GFI stand for?

The term GFI stands for Ground Fault Interrupter. A Ground Fault Interrupter is a crucial safety device used in electrical systems to protect people from electric shock by monitoring the flow of electrical current. It operates by comparing the input and output current and can detect if there is an imbalance, which typically indicates that current is leaking or flowing through an unintended path, such as through a person who is touching a faulty ground or connections. When such an imbalance is detected, a GFI can quickly disconnect the power, significantly reducing the risk of electrical shock and injury.

This piece of equipment is particularly important in wet areas, like bathrooms and kitchens, where the risk of electric shock is heightened. Understanding the function and importance of a Ground Fault Interrupter is vital for safety in construction and electrical work, highlighting the significance of using this technology in various applications.
