The role of GFCIs in household electrical safety

GFCIs are designed to protect against electric shock hazards by quickly shutting off the power when a ground fault is detected. Ground faults occur when electrical current deviates from its intended path and flows through an unintended connection, such as through a person or water. GFCIs are commonly installed in areas where there is a higher risk of electrical shock, such as kitchens, bathrooms, garages, and outdoor outlets.

They constantly monitor the flow of electricity and can trip within milliseconds to prevent serious injuries. GFCIs provide an added layer of protection by reducing the risk of electrical shocks, especially in wet or damp environments where the chances of grounding faults are higher. Periodically test GFCIs to ensure they are functioning correctly.

If a GFCI repeatedly trips or fails to reset, it may indicate a fault in the circuit or a malfunctioning GFCI device, which should be inspected and repaired by a qualified electrician.
