If you want to use a source with the maximum wires already present, it may be possible to split the source before it enters the box. Cut access to the wiring through the wall material and add a junction box to splice the new outlet into the circuit. Cover the box with a blank plate to protect the splice.
Electricity that is flowing from one place to another is called current. The volume of electrical current is measured in amperes or amps.
Attach the wires to a new switch connecting the hot source to the bottom terminal and the wire running to the light to the top terminal. On a receptacle the black wire from the source goes on the hot, brass colored screws and the white goes to the neutral, silver colored screws. If there are two sets of wires on a receptacle, keep them in sets using the top terminals for one and the bottom terminals for the other set.
Apply caulk to the back of the strip and stick it to each stud. Press it down until it’s flush with the wall surface. You can leave the wallboard off, but it’s best to put it back in place. Caulk along the seam to seal out air drafts and then reinstall the baseboard.
A current-carrying wire in an electrical circuit, also called the grounded circuit wire, it serves as the return path for current, and is connected to ground at the service panel. In household electrical circuits the neutral wire is colored white or gray. Some circuits make use of the white or gray wire as a hot wire, when this is done it will be marked with black tape or paint to identify it as hot.
Carefully nail the molding just above and/or below the metal shield at each stud. Caulk the trim seams, fill the nail holes, and touch up the wall and molding paint.
An easier alternative to repairing the damage is to use one coat of mud and then cover the rough repair with a preformed medallion. A plastic medallion can be installed using caulk to stick it to the surface or using the fixture cover plate to hold it in place. You can also get a plaster medallion, these should be installed using setting joint compound or plaster of Paris to attach it to the ceiling. Keep pressure on the medallion to hold it in place until the mud has set.
There will probably be several options for an electrical source to serve a new outlet. For instance, it is likely there are several suitable wall receptacles in any given room to extend the circuit to another room or another floor of the house.
