The safest way to connect wires is to use the outlet's side screw terminals, a procedure known as sidewiring. Another common method, called backwiring, uses self-clamping rear terminals that do not screw down the wire; this method is unsafe because the wires can come loose from these terminals.
There are two approaches to physically connecting electrical wires to an electrical receptacle ("Outlet") or to an electrical switch ("light switch" or "wall switch"). Back-wiring means connecting the wire through an opening or into a clamp accessed on the back of the receptalce or switch.
Feed in enough cable to reach the new outlet location—plus about 1 ft. Connect the wires of the new cable to the existing wires (Photo 3). Pull the cable out through the new outlet hole in the wall (Photo 4) and feed it into the new box.
Electrical Question from Tony about Outlet Wiring Directions Background: Tony, a Homeowner from Newport News, VA Question: I bought a new outlet with 5 screws in it. But when I removed the old outlet, I see only 3 wires coming out.
Wiring Multiple Outlets in a Series. In this diagram wall outlets are wired in a row using the terminal screws to pass voltage from one receptacle to the next. Wiring outlets together using the device terminals, instead of a pigtail splice as shown in the next diagram, can create a weakest link problem.
Connect this jumper wire back to the switch terminal. Now, remove the wire cap from the two white wires in the box, add the white wire from the outlet and reset the cap. You may need a larger cap. Finally, add the ground wire to the two already attached to the ground screw, either by twisting the wires together or connecting them with a crimp ring.

Connect the black wires to the brass terminals on the outlet you're wiring, connect the ground wires to the ground terminal, then twist the white wires together and cap them. Follow this procedure for all but the last outlet in the circuit.
Being able to wire an outlet is a great skill to have in your repertoire, and, once mastered, you’ll be able to replace old or damaged outlets in a matter of minutes. To help you know what to expect, I’ve created a tabletop guide with pictures illustrating how to properly wire an outlet.
