Which devices should be tested for GFCI functionality?

Testing all Ground Fault Circuit Interrupter (GFCI) devices is essential for ensuring safety and functionality. GFCIs are critical in preventing electrical shocks by quickly shutting off power when they detect an imbalance in electrical current, which often occurs in wet areas where there is a higher risk of electric shock.

Test procedures should be conducted on all GFCI devices because they are found in various locations, including bathrooms, kitchens, outdoor areas, garages, and other locations where moisture is present. Each of these devices plays a crucial role in protecting users from potential hazards. Regular testing can help determine if the device is functioning correctly and can be crucial in preventing electrical accidents.

Focusing on only specific GFCI devices, such as those found in outdoor areas or kitchens, would leave other critical areas unmonitored and increase the risk of electric shock in those spaces. Therefore, a comprehensive approach that includes all GFCI devices ensures maximum safety for users throughout a building.
