Title Definition
GFI or GFCI or Ground Fault Current Interrupter

A electrical device used to prevent injury from contact with faulty electrical appliances and faulty wiring - electrical shocks. GFIs should not be confused with AFIs, the later are designed to prevent electrical fires. GFIs are required in new home bathrooms, kitchen, garage, out of doors and in other locations where one might be in contact with a grounded surface and an electrical appliance. Most GFI's are located in the receptacle itself and can be identified by the presence of a 'test' and a 'reset' button.
