GFIs are different from regular outlets. GFI or GFCI (Ground Fault Circuit Interrupters) are installed outdoors or near places where water is present. A GFI can detect when a current in appliances is no longer flowing in its proper circuit and then shuts down the current within milliseconds. These look different than traditional outlets and have two buttons on them, “Test” and “Reset”.
Take a look in your kitchens, bathrooms, and garages to see if you have the correct outlets installed. Be sure to test them often to see if they are still working properly.
