How To Wire Multiple Outlets And Lights On Same Circuit?

Home Tips

It is possible to wire multiple outlets and lights on a similar circuit as long as the course does not supply more than 80 percent of the circuit breakers limit. This is a safety precaution that ensures you enjoy a constant power supply without the circuit breakers tripping continuously when in use. One needs to confirm with the authorities to know what the limitations are. The important thing is to understand how this works. Read on to discover how this is done. 

How To Wire Multiple Outlets And Lights On Same Circuit?

Tools to Use

Several tools are required to get this done and connect your extension cord with multiple outlets and lights in the same circuit. These include:

  • Extension cord
  • Ammeter
  • Voltmeter
  • Wires
  • Black tape
  • Continuity tester
  • Pliers

Understanding the Wires

Before you start with the connection, you must first figure out the wires to know which ones are hot and which ones are not. It is necessary to pay attention to the wiring system every time you are following a DIY procedure. 

Please pay special attention to the colors of the wires since they have a specific indication. For instance, standard 120-volt wiring will have the neutral wire in white since the national electric code dictates. The hot wires will come in black, purple, or red, with the conventional color being black. Finally, the ground color will be green or bare copper. Please take note of these colors since they affect the connection you make moving forward.

Besides the wires, terminals are also color-coded regardless of whether they are on a switch, outlet, or fixture. Chrome screws are indicative of neutral terminals, while brass screws are hot terminals. The green screws will be used with the ground wires. The same color-coded rules apply to plugs and make it easy to identify them.

Standard Daisy Wiring

There will be two cables in the outlet box to wire an outlet in the middle of the chain outlets. One of the wires is live and comes from a different device with power or direct from the panel. The second cable goes to the next outlet in the chain.

You need to turn off the breaker and use the voltage tester to test that the power is off. Once confirmed, connect the black wire from the live cable to the brass terminal on the outlet. Similarly, click the white wire from the live line to the chrome terminal’s top. You can also choose to start with the bottom pair, but it is easier and more straightforward to start with the top couple.

Next, connect the outgoing black wire to the brass terminal’s bottom side, the hot wire. Similarly, the white neutral wire should be connected to the chrome terminal’s bottom side. To complete the process, twist the ground wires together and connect to the green wire, which is the ground terminal.

If you do this correctly, then the outlet will continue to pass power to the rest of the outlets in the same chain even when plugged in burns out. The only downside to this type of connection is that in case of a serious power surge that can damage the terminals’ connecting plates, the rest of the terminals will go out with them.

If you want to avoid power outages, consider creating pigtails in the connections. This can be done by simply twisting together same-colored multiple wires and adding an extra short spare wire of the same color. You need pliers to help you twist these wires clockwise. Once turned, you need to screw a white cap on top. This does because it splits the electrical paths, creating a way to power the outlet you are wiring but also to those downstream. No pigtail is needed for the ground wires. You can twist them together to the ground just as you do in the standard wiring procedure.

FAQs

1. How many lights and outlets can be connected in one circuit?

You can use a maximum of 12 outlets for every connection. This is the recommended maximum that can be connected to a circuit. The composition may comprise 12 light outlets or 12 plug outlets but not appliance plugs. Alternatively, you can use any combination of light and plug outlets as a mix, as long as they do not total to more than 12 outlets. If you have no idea how to go about this, consider working with a certified electrician.

2. Is it possible to wire light outlets on a similar circuit?

Basically, Yes. But before you do this, it is best to check with the local authority in your area how much limitation is allowed. The last thing you want is to get into legal trouble for your ignorance. The bottom line is that the C circuits will be wired in parallel circuitry.

3. What is the easiest way to wire multiple receptacles?

Simply twist them together and connect one of them to the ground screw just as would happen in a standard outlet wiring system. Once you make the pigtails with your black and white wires, make sure to connect the short jumper black wire to the outlet’s top brass terminal. On the other hand, the white jumper should be connected to the top chrome terminal.

4. Why would the outlet have two black and two white wires?

Your two black conductors should be electrically bonded using the receptacle, just like the two white conductors are. You may notice that the receptacle’s side’s bonding tab is still in place, meaning that the two receptacles are connected. 

5. Why is it that my outlet has two hot wires?

Outlets may have two hot wires, in which case one wire functions as an ‘always on’ transmutation from the power supply that feeds the other wire. The second hot wire, in turn, transmutes the voltage to another device or series of devices.

Final Thoughts

It is easy to wire multiple outlets and lights on the same circuit as long as you know what to do. Find a simple-to-follow procedure if you intend to make a DIY connection. You do not have to be a certified electrician to do this, but an understanding of electric functionality is advised.
