Wiring Two Outlets In The Same Box. To connect the receptacle with pigtails each of the black white and ground wires in the two cables in the box are joined together with a short length of wire called a pigtail. Normally the pigtail will be a wire with the same color coding as the circuit wires.
In this diagram wall outlets are wired in a row using the terminal screws to pass voltage from one receptacle to the next. The other cable goes to the next outlet in the chain. Using this method any break or malfunction at one outlet will likely cause all the outlets that follow to fail as well.
Turn off the power to the circuits you are working on by flipping off the circuit breakers.
The white neutral wire is splice to each outlet so they share the return path. Wire or rewire multiple outlets in one box. If you re wiring an outlet in the middle of a chain of outlets you ll have two cables in the outlet box. Connect the new wires to the new outlet.
