To install and wire in a new electrical outlet from an existing outlet:
For this method to work, the existing outlet needs to be located on the opposite wall of the new location and be the most common wiring of 14-gauge wire on a 15-amp circuit.
Turn off the power at the main electrical panel and ensure the power is off at the existing outlet by testing it with a voltage tester.
Remove the face plate on the existing outlet and pull it out from the box. Feed in 14-gauge wire through one of the back knock-out holes, adding in enough cable to reach the new outlet, as well as an extra foot.
Expose the wire on the new cable by stripping off 10 inches of the plastic sheathing, then push the new cable up inside the box, wrapping it around itself to hold it in place. Strip off the insulation from the ends of the new wire, and connect the new wires with those in the existing outlet, connecting white with white, black with black and ground with ground. Cap off the ends.
Cut out the new hole for the outlet box and pull through the new cable from the wall. Install the new outlet box, and then connect the wires with the new outlet. Secure the wires and the outlet inside the box, and attach the face plate.
