How To Wire A Double Electrical Outlet – Get rid of unsightly and sometimes dangerous extension cords. You can add a new outlet quickly and easily without tearing up the wall if you have an electrical outlet on the other side of the wall. There are no special holes. No processing and messy coloring. The steps presented here allow us to mount our TV on the wall in the family room without an outlet. Since there is an electrical outlet on the other side of this wall (facing the next bedroom), we added a new outlet in the family room, which draws power from the outlet in the bedroom.
This technique only works if you can use an electrical outlet as a power source opposite or nearly opposite where you want your new outlet. To determine how to wire and whether you can safely use an existing outlet, follow the list below.
How To Wire A Double Electrical Outlet
Confirm the required box size with your local building inspector. In most areas, you will need an electrical permit for this work from your local building department. This helps ensure safe work. Listed below are the 8 most common violations of the National Electrical Code.

Before tackling any part of this project, turn off the circuit at the main electrical panel by closing the switch or removing the fuse.
Before touching an exposed wire or terminal on a switch or outlet, use a voltage tester on all wires to make sure they are closed. If you have old cloth insulated cables, call an electrician to suggest a safe connection. In this type of wiring, there is usually no ground wire and it is difficult to distinguish the hot wire from the middle wire, since both are coated with black insulation.
Aluminum wire requires special care. If you have aluminum wiring, have a licensed professional work on it. This wire is light gray, not the pale orange characteristic of copper.

There are several methods of replacing the cables and half cables outside. Generally, the outlet will receive the same wire as if there was a fire.

Alternatively, you can get an outlet where half the outlet is replaced and the other half is constantly live. Here are two alternating wiring diagrams showing isolated wiring.
If your intention is to replace a thermostatic valve to control an existing ceiling fan or light switch, you should click here to read my blog post with pictures on how to do this.
The switch wiring diagram shows the current from the circuit entering the toggle outlet box, where two wires go to the switch and the other two wires send current to another outlet that is always active.
The wiring diagram above shows how electrical outlets are typically wired. Although Section 404.2(C) of the National Electrical Code (NFPA 70) requires that wall switches that control light fixtures also have a neutral conductor, valve control switches are exempt from this requirement.

A neutral conductor is required for lights in the case of converting a standard wall into a smart home device or other type of control such as a timer.
I think it’s worth including a neutral for the wall switch that controls the outlet anyway, because a normal wall switch can also be turned into a smart home device that usually requires a neutral conductor to work.
It is common practice among the uninitiated to use a neutral ground conductor whenever there is no wiring. This is an unsafe and potentially dangerous practice.
When the white wire is used as a hot wire or LINE, it is necessary to set a new white wire of a different color. However, in my experience working on older homes, white wire almost never changes color when used as wire. So it is not unusual to find that the white wire in the breaker box is the wire and not the neutral conductor. A non-contact voltage probe is good for checking wires that are hot
Residual Current Device
Any outlet that children have access to, including kitchen counter outlets, should be sealed. They prevent plugging things in as children are known to do. Section 406.12 sets forth the requirements of this code.
Wiring diagram of a switched outlet and an unswitched electrical outlet with current entering the electrical switch box from the switch panel. A single pole switch has a neutral conductor for future electronic controls such as timers or WiFi switches.
In the diagram below, the power is shown by the circuit breaker panel. The same wiring diagram can be used if the power comes from a different outlet and connects to the outlet shown on the back.
In the diagram above, the hot and neutral wires go into the single pole switch box. Then 3 conductors are placed in the switch. Two conductor cables are installed from the outlet alternately to supply the live valve at all times. Two conductor wires run from the switch box to another pair of sockets that remain active all the time.
Wiring One And Two Pole Breakers
The following two switching wiring diagrams illustrate how to connect insulated or semi-switched cables. The first shows how there is a neutral conductor in the breaker box. The diagram below shows how this is usually done.
Split jacks are standard two-tier jacks that have cut tabs to separate the top and bottom. In the drawing below only the rod on the LINE side of the socket is cut because the top and bottom serve as the same center.
A half-switch wiring diagram shows that electricity enters an electrical outlet and then goes to a switch and another outlet.
The outlet is split into wires so that the top half of the receiver is always on and the bottom half of the receiver is controlled by a wall switch. Shown below is the neutral conductor in the breaker box as well as the location of the disconnect in the outlet.
How To Wire An Outlet And Add An Electrical Outlet (diy)
The top socket has a notch on the hot wire side to make it a separate socket. Now the fixed hot wire can be attached to one screw and the variable hot wire can go under the other screw.
There is no need to cut the strip on the neutral side if the top and bottom of the outlet are on the same circuit. If there are two separate circuits, two neutral boards may be required and the neutral strip must be cut. If a multi-wire circuit is used, it is not necessary to cut the neutral strip.
A multi-wire circuit consists of three wires with two hot and one neutral wire in addition to the equipment ground conductor. It is connected with a bipolar circuit breaker.
Depending on the brand of receiver, you can break the strap between the top and bottom of the jack by using a needle nose needle to bend the strap back and forth or small pliers to cut it.
How To Count Wires In An Electrical Box
Three different two-level sockets on the sides have a separate strip to create a separate receiver.
In the wiring diagram below, the white wire going to the switch is used as the hot lead, not the neutral. When using a white wire as a hot wire or LINE, it must be reconfigured to a color other than white, gray or green.
The switch controls the lower half of each individual burner. The three-conductor cable is used to bring the hot wire, switch leg, and neutral conductor to the receptacle on the right.
It does not show the required ground conductor to simplify the wiring diagram. However, each outlet and switch must have its own green screw connected to the appliance’s ground conductor. Click here to see my post on how to disconnect or switch.

Only one ground wire can go under the green screw. If you have multiple ground wires, braid them together. The braid is attached below the green screw.
There are green wire connectors with holes that allow one long wire to be used as a braid and the other wire to wrap around it.
