A correctly wired GFCI receptacle can protect how many receptacles farther down the circuit?

A correctly wired Ground Fault Circuit Interrupter (GFCI) receptacle is designed to provide protection against ground faults, which can occur when electricity is inadvertently directed to the ground, posing a potential shock hazard. When a GFCI is installed, it monitors the current flowing through the circuit. If it detects an imbalance between the incoming and outgoing current, it quickly disconnects power to prevent electrical shock.

When a GFCI receptacle is wired correctly, it can protect not only itself but also any other receptacles that are connected downstream on the same circuit. This means that as long as the additional receptacles are wired correctly, all of them can benefit from the ground fault protection provided by the GFCI. This makes it a crucial safety device, especially in areas prone to moisture, such as kitchens, bathrooms, and outdoor spaces, where the risk of electrical shock is higher.

Thus, the correct answer is that a GFCI receptacle can protect all receptacles further down the circuit, ensuring comprehensive safety across multiple outlets connected to it.
