What does GFI stand for in electrical safety?

GFI stands for Ground Fault Interrupter, which is a critical safety device in electrical systems. It is designed to protect individuals from electric shock by detecting imbalances in electrical current. When a ground fault occurs—meaning that some of the current is flowing through an unintended path, such as a person— the GFI quickly cuts off the electrical supply, reducing the risk of severe injury or fatality. This technology is particularly important in wet locations, such as bathrooms or outdoor areas, where the risk of electrical hazards is heightened due to the presence of moisture.

Understanding the role of a Ground Fault Interrupter is key in ensuring electrical safety, particularly in settings where people are at greater risk of encountering live electricity. This device is an essential component in modern electrical systems, designed to safeguard the health and safety of users.
