Ground Fault Circuit Interrupter (GFCI) outlets should be used where water is present, creating potential electrical hazards. These areas include: Kitchens: GFCI outlets are essential in kitchen spaces where water and electrical appliances are frequently used. Bathrooms: Bathrooms often have GFCI-protected outlets to protect against electrical shocks in wet environments. Garages: Since garages can be exposed to moisture, GFCI outlets enhance the safety of tools and equipment. Outdoor Spaces: GFCI outlets are necessary for outdoor areas, including patios, decks, and garden areas, where they protect against weather-related electrical hazards.
