The other caveat is that only outlets connected to three wires are suitable for DIY replacement. Outlets with three attached wires (remove the outlet plate to determine the number of attached wires) indicate that the outlet is located at the end of an electrical circuit (a wiring loop that starts and finishes at the breaker panel). An outlet with five attached wires is located in the middle of an electric circuit, and the wiring process is more complicated—only a licensed electrician should replace those outlets.

What is a GFCI socket?
GFCI stands for Ground Fault Circuit Interrupter. These devices replace standard electrical outlets and work by comparing the input current on the ‘hot’ side of the outlet to the output current on the neutral side. Any difference in these two numbers means that current is ‘leaking’ somewhere – potentially into a person – and the power supply to the device is cut off immediately. This, therefore, protects you while using any device plugged into a GFCI socket.

Can a GFCI be protected?
In most cases, no. For example, all of the bathroom receptacles throughout a house can be protected by one GFCI receptacle. This is true for the receptacles at a kitchen counter that are required to be GFCI protected. You may only see one GFCI receptacle, but all down-circuit receptacles can be protected if installed properly. The GFCI receptacle simply needs to be located closest to the breaker on that circuit.
