GFCI receptacles can protect which of the following if properly wired?

GFCI receptacles, or Ground Fault Circuit Interrupter receptacles, can indeed protect downstream receptacles if they are properly wired. When a GFCI is installed in a circuit, it monitors the current flowing between the hot and neutral wires. If it detects an imbalance, which indicates a ground fault, it quickly cuts off the power to prevent electric shock.

When wired correctly, the GFCI can provide ground fault protection to any receptacles or devices that are connected downstream on the same circuit. This means that if any additional outlets or devices are connected after the GFCI in terms of the electrical circuit, they will also receive the same protection as the GFCI outlet itself. This is critical for enhancing safety in areas where electrical outlets may be exposed to moisture, such as kitchens and bathrooms.

The other options do not accurately reflect how GFCI outlets function. They do not only protect the receptacle they are connected to but can extend protection to additional downstream outlets. They do not protect upstream receptacles; if there are other outlets connected before the GFCI in the circuit, they won’t receive GFCI protection unless they are also connected to a GFCI. Additionally, GFCI receptacles cannot protect outlets
