What type of receptacle(s) can be used in place of a non-grounding-type receptacle when there is no equipment grounding conductor?

• A. Standard duplex receptacles
• B. GFCI-type receptacles
• C. Smart receptacles
• D. Weather-resistant receptacles

Answer: (B)

GFCI-type receptacles are designed to provide protection against electrical shock by detecting ground faults and interrupting the electrical circuit if an imbalance occurs. This makes them suitable for use in locations where a grounding conductor is not available. When replacing a non-grounding-type receptacle, GFCI receptacles can be used as they don't require a ground wire to safely function. Instead, they monitor the current flowing through the circuit and can cut off power within milliseconds if a fault is detected. The use of GFCI receptacles is particularly important in areas where moisture is present, such as kitchens, bathrooms, and outdoor locations, as it enhances safety under conditions that increase the risk of electric shock. This capability allows them to serve as a safe alternative to traditional receptacles in situations lacking a grounding system. In contrast, standard duplex receptacles require a grounding conductor to function safely and effectively; smart receptacles often rely on grounding for their advanced electronic features; and weather-resistant receptacles, while suitable for outdoor use, still generally require grounding to ensure safety.
