In this educational article, we will explore the workings of power outlets, focusing on the color coding and terminology commonly used in North America. However, the fundamental concepts are applicable globally. It’s important to note that working with electricity can be hazardous and should only be performed by those who are qualified and knowledgeable.
A typical power outlet, or receptacle, consists of several key components. On the left side, you will find two neutral terminals, which are silver in color. On the right side, there are two brass-colored hot terminals. Additionally, a green ground terminal is present. These terminals are connected by a jumper, which plays a crucial role in the outlet’s functionality.
Inside the outlet, there are tracks that facilitate the flow of electricity. The jumper connects the two neutral and two hot terminals, allowing both hot terminals to be energized if either one is connected to the electrical circuit.
To integrate the receptacle into the electrical system, the hot wire is connected to the hot terminal, and the neutral wire is connected to the neutral terminal on the opposite side. For safety, the ground wire is also connected. When power is activated, electricity flows through the hot wire into the tracks for the hot terminals. The electricity aims to return to the service panel via the neutral terminals, but the circuit remains incomplete until a device is plugged in.
With the jumper in place, both hot terminals are energized, allowing a device plugged into either socket to complete the circuit. Removing the jumper isolates the terminals, meaning only the terminal directly connected to the hot wire will be energized. This setup is useful for specific applications, such as switch receptacles.
One practical application of removing the jumper is in switch receptacles. This configuration allows one half of the receptacle to remain constantly powered, while the other half is controlled by a switch. To achieve this, the hot wire is connected to a wire nut, and an additional hot wire is run to the top hot terminal. The neutral wire is connected back to the service panel, along with the ground wires.
When powered, only the top half of the receptacle is energized. To connect the lower half to a switch, a white wire (marked with tape to indicate it is hot) is run from the hot wire nut to the lower terminal of the switch. A black wire is then run from the top terminal of the switch to the lower terminal of the receptacle. The ground wire is also connected for safety.
With this setup, flipping the switch completes the circuit, allowing electricity to flow to the lower half of the receptacle. Turning off the switch cuts power to the lower half, while the top half remains powered.
Another application involves connecting two different hot wires by removing the jumper. By introducing a red hot wire alongside the black hot wire, the top and bottom halves of the receptacle can be connected to separate circuit breakers. This configuration helps distribute electrical demand across two breakers, reducing the risk of overloading and tripping a breaker.

In this video, we will be using color coding and terminology specific to North America. However, if you’re from outside this region, you can still follow along and learn how these concepts work. We will be covering the theory in this video, but please remember that electricity is dangerous and can be fatal. You should be qualified and competent to carry out any electrical work.
Let’s take a look at a typical receptacle. You’ll find two neutral terminals on the left, which are silver in color, and two brass-colored hot terminals on the right. Additionally, there is a green ground terminal. Between these sets of terminals, there is a jumper, which we will discuss later in the video. Inside the outlet, there are tracks that carry electricity. The two neutral and two hot terminals are currently connected by the jumper, meaning both hot terminals will become energized if either one is wired into the circuit.
We can remove the jumpers using pliers, but these cannot be replaced once removed. By snapping these off, we can isolate the terminals and connect them to different circuits, which we will explore in detail later. For now, I will leave the jumpers in place.
To connect this receptacle to the electrical system, we first bring in our hot wire and connect it to the hot terminal. Next, we connect the neutral wire to the neutral terminal on the opposite side. To ensure the circuit is safe, we also bring in our ground wire. When we turn on the power, electricity will flow along the hot wire into both tracks for the hot terminals. The electricity seeks to return to the service panel via the neutral terminals, but it cannot complete the circuit at this moment.
With the jumper in place, both hot terminals are energized. If we remove the jumper, only the terminal connected to the hot wire will be energized. To complete the circuit, we need to plug something into the receptacle. For this example, I will plug in a simple light. With the light plugged in, electricity can now flow through the hot terminal into the plug, then along the cable into the lamp. From there, it returns to the neutral terminal of the outlet and back to the service panel.
With the jumper in place, the lamp will light up if plugged into either socket. However, when we remove the jumper, the circuit is broken, and the lower hot terminal will no longer power the lamp. We can still plug the lamp into the top circuit to complete the circuit and power the lamp.
So, why would we want to remove the jumper? One application is when using switch receptacles, which allows half of the receptacle to remain hot while the other half is controlled by a switch. For this, we connect the hot wire to a wire nut and run another hot wire from there to the top hot terminal. We then run our neutral wire back to the service panel, ensuring we also include our ground wires.
If we power this circuit, only the top half will be hot, while the lower half will have no power. To connect the lower half to the switch, we run a white wire from the hot wire nut to the lower terminal of the switch, placing tape on this wire to indicate that it is hot. From the top terminal of the switch, we run a black wire to the lower terminal of the receptacle. To ensure safety, we also bring in our ground wire.
When we power this circuit, electricity flows to the top terminal, and we have provided a second path leading to the switch. If the switch is off, electricity cannot pass through it, but when we flip the switch, the circuit is completed, allowing electricity to flow to the lower half. If something is plugged into either socket, electricity can flow through and return to the service panel.
If we turn the switch off, power is cut to the lower half, but the top half remains hot. Another application is connecting two different hot wires. By removing the jumper and bringing in a red hot wire along with the black hot wire, we can connect the top and bottom halves to different circuit breakers. This helps distribute the electrical demand over two breakers instead of just one, reducing the likelihood of overloading and tripping the breaker.
