A GFCI outlet, or ground fault circuit interrupter, is a special type of electrical outlet designed to protect people from electrical shocks. GFCI outlets are required in certain areas of the home, such as bathrooms, kitchens, and outdoor areas. They work by monitoring the electrical current flowing through the outlet. If the current suddenly changes, such as when a person comes into contact with a live wire, the GFCI outlet will trip and shut off the power.
GFCI outlets are an important safety feature that can help to prevent electrical shocks and electrocutions. They are relatively easy to install and can be purchased at most hardware stores. It is important to note that GFCI outlets should only be installed by a qualified electrician.
