How to Read These Diagrams. This page contains several diagrams for 2 or more receptacle outlets in one circuit. Wiring for multiple ground fault circuit interrupters gfci and standard duplex receptacles are included with protected and non-protected arrangements.
In this diagram wall outlets are wired in a row using the terminal screws to pass voltage from one receptacle to the next.
How to Wire a 110-Volt Outlet
Wiring outlets together using the device terminals, instead of a pigtail splice as shown in the next diagram, can create a weakest link problem. Using this method, any break or malfunction at one outlet will likely cause all the outlets that follow to fail as well.
This diagram shows the wiring for multiple receptacles in an arrangement that connects each individually to the source.
All wires are spliced to a pigtail which is connected to each device separate from all the others in the row. This wiring allows for source voltage at each outlet independent of the others in the circuit.
Here 3-wire cable is run from a double-pole circuit breaker providing an independent volts to two sets of multiple outlets. The neutral wire from the circuit is shared by both sets. This wiring is commonly used in a 20 amp kitchen circuit where two appliance feeds are needed, such as for a refrigerator and a microwave in the same location.
In this diagram multiple ground fault circuit interrupter receptacles are wired together using pigtails to connect the source. Two-wire cable is run between the gfci's, and the hot and neutral wires from the source are spliced to the line terminals at each device.
The load terminals are not used and each device provides its own, single-location protection. Here a gfci receptacle is added at the end of a row of duplex receptacles for single-location protection.
The first outlet is connected to the source and 2-wire cable runs from box to box. All wires are spliced with a pigtail at the devices to pass current to the next. The load terminals on the gfci are not used and it does not protect the other receptacles in the circuit. Here one ground fault circuit interrupter protects multiple duplex receptacles coming after it, known as multiple-location protection.
Two-wire cable runs from the gfci to all the following outlets. The line terminals on the gfci are connected to the circuit source and the load terminals are connected to each following outlet with a pigtail splice.
This keeps each duplex receptacle connected directly to the gfci. By code there is a limit to the number of conductors allowed inside an electrical box depending on the wire gauge you're using and the size of the box. While wires are conductors, they aren't the only ones in an electrical box.Wiring a V electrical outlet is a do-it-yourself task that can be completed by anyone with common tools. Modern homes all have 3-plug outlets that are comprised of a hot side, a neutral side and a ground wire.
Older homes have 2-plug outlets that do not have a ground wire but are wired with the hot and the neutral in the same way.
How to Wire a Double Outlet
Turn off the power to the outlet on the breaker panel. Check the outlet by inserting the probes on a voltage tester into the outlet plugs. If there is no power, the tester will not light up. This doesn't mean that power has been cut off to the outlet because the outlet may be bad. Remove the center screw from the outlet cover and take the cover off.
At this point, you will be able to see the wires that attach directly to the outlet. Test the wires directly with the voltage tester. If the tester lights up, throw the main breaker on your panel to the "off" position. Test the wires directly again. If the tester still lights up, stop what you are doing and call in a certified electrician to determine the problem with your wiring.
Remove the outlet receptacle holding screws with a screwdriver when you're assured that the power is off. There will be one screw at the top and one at the bottom.
Pull the outlet out of the receptacle box. Attach the wires onto the the terminals on the new outlet. Pull the sheathing off and expose the bare wire. Make little hooks on the ends of the wires and wrap them around the electrical terminals.
The black hot wire goes to the gold terminal, the white neutral wire goes to the silver terminal and the green or bare copper ground wire goes to the green colored terminal. Tighten down the terminal screws firmly. Dale Yalanovsky has been writing professionally since He specializes in do-it-yourself projects, household and auto maintenance and property management.

By Dale Yalanovsky.If you want to install an electrical double outlet, you should know that it is a little different from a single one. However, the wiring is actually very easy and can be completed in just a few minutes. This simple step-by-step guide will show you everything you need to know, so let's get started! Before you start, go to your home's main breaker box and shut off the Circuit Breaker that provides electricity to where you will be working.
Once the power has been shut off, test the circuit with a multimeter or test light just to be sure there's no current flowing. Ensure that the junction box where you will be installing the new double outlet already has wiring that runs from the main circuit breaker.
Use the needle-nose pliers to create a hook in the piece of bare copper wire that will be used to ground the new double outlet as well.
After you have prepared the wiring in the junction box, install the first outlet by securing the black wire to the screw terminal with the brass colored screw. Attach the white wire to the silver-colored screw terminal after, and then connect the bare copper piece of wire to the ground screw at the bottom of the electrical box along with another piece of bare copper wire about 6" long.
The bare copper wire can next be looped and secured around the outlet's green ground screw but leaving enough of it to reach the same screw on the next receptacle. To install the second outlet, use the black short wire and secure each end to the brass-colored terminal on each receptacle, the do the same with the white short wire but this time connecting to the silver-colored terminals. To connect the ground wire, take the piece of bare copper wire hanging from the first outlet in Step 3 and secure it to the green ground screw on the second outlet.
Now that the wiring to the receptacles is complete, install the wires on the mounting plates in the junction box. Then, place the cover plate over the two outlets, and secure with the retaining screw.

This page contains wiring diagrams for two outlets in one box. Included are arrangements for 2 receptacles in one box, a switch and receptacle outlet in the same box, and 2 switches in the same box. In this diagram, two duplex receptacle outlets are installed in the same box and wired separately to the source using pigtails spliced to connect the terminals of each one. With each outlet connected by its own pigtail wire, if one fails because of physical damage, the other won't be affected and should still work.
Here two outlets are installed in one box and wired using the device terminals to connect them. With this arrangement, if receptacle 1 fails, receptacle 2 may also fail. If the first outlet in the circuit is damaged internally in some way, it may affect the flow of electricity to the outlets that follow. Usually this is not the case though. If the copper tab between the terminals screws remains intact, even if 1 stops functioning, outlet 2 will most likely still work.
In this diagram, two outlets are wired in the same box with a separate volt source feeding each. Three-wire cable runs into the box. The black and red wires are both hot and each is connected to one of the receptacles.
The white, neutral wire is splice to each outlet so they share the return path. This is appropriate for standard duplex receptacles, but should not be used for GFCI receptacles.Wiring a V outlet, like switch wiring, is a basic electrical task that every homeowner should know how to do.
An electrician charges a hefty fee for this job, and it takes less than 30 minutes to complete, even for a novice. If the reason you haven't learned how to do this yet is that you have a healthy respect for the hazards of working with electricity, you're right to have that respect.
However, if you take a few precautions, you have nothing to fear. Residential electrical devices all use a standard color code for wires and terminals, and if you follow it, it's almost impossible to wire a V outlet incorrectly.
By the way, if you're wondering why the outlet you just bought has a label indicating it's for a volt plug or a volt plug, don't worry. Residential circuits are rated for, or volts. All these numbers mean basically the same thing. Whether you're replacing a worn V outlet or installing a new one, you'll need to make sure there is a live circuit cable in the electrical box, which should be firmly nailed to a stud or secured to the face of the drywall.
The cable is connected to one of the breakers in the panel, so the first thing to do is to find that breaker and shut it off.
Double check the circuit wires with a voltage tester before you start wiring. The tester light should stay off when you touch one lead to the black wire and the other lead to either the white one or the bare one. Once you verify the wires are dead, you can touch them with impunity, but it's still a good idea to use tools with insulated handles just in case. There may be another cable in the box, and if so, it's feeding another fixture.
It is probably dead, but you should check it as well just to make sure. If you look at the receptacle you're about to install, you'll see it has two pairs of brass and chrome terminals arranged across from each other. You only need one pair to energize the outlet. The second pair is for daisy chaining another circuit device downstream in the circuit. The brass terminals are for hot connections. When you insert a plug, they determine which side of the plug is hot. You always attach black wires to brass terminals.
Similarly, the chrome terminals are neutral and are only for white wires. The green terminal at the bottom of the outlet is for the ground wire. You can connect the live circuit wires to either pair of terminals, but to avoid confusion, choose the top pair and leave the bottom pair open for daisy chaining. Making this choice consistently simplifies troubleshooting when a problem occurs. The LOAD terminals are for downstream devices only. Loosen the terminal screws and wrap the exposed ends of the wires around the screws, bending the wires clockwise with pliers before tightening the screws.I called up electrical experts to upgrade my electrical wiring, so he installed MCB at mains power supplyand did all the necessary actions with great perfectness.

The information you shared was useful.A circuit breaker is what controls the power to an electric circuit. The circuit breakers in the main service panel of a house are typically rated for volts or volts.
Most home devices, such as lighting and most outlets, are wired to volt breakers. When you add a new circuit, you will need to installing a v breaker in the service panel to complete the circuit.
Be sure to talk with an electrician if you have any question before beginning this project. Turn the main power breaker to the service panel to the Off position. The main breaker is typically labeled and located at the top of the service panel.
Use your screwdriver to remove the screws securing the service panel's cover door. Remove the door and set it and the screws to the side for later reassembly. Locate an open bay or slot in the service panel to insert the new circuit breaker. Line up the circuit breaker over the slot. Slide the breaker into the slot and push down to lock the U-shaped clamps on the bottom of the breaker onto the pins in the slot.
You will hear the breaker snap into position. Strip 1 inch of insulation from the ends of the wiring that is to be connected to the breaker you have installed. Attach the bare wire to the grounding strip at the bottom of the service panel.
Attach the white wire to the neutral bus strip running down the center, and attach the black wire to the single screw on the breaker. Use the screwdriver to tighten all the screws to hold the wires in place. Line up the cover door with the service panel and punch out one of the knockout slots to allow the breaker's switch to extend through when the door is reassembled.
Use the screwdriver to punch out the tab. Replace the cover door and secure it in place with the screws you removed earlier. Tighten them with the screwdriver. Never work on a service panel without turning off the main breaker to the panel. The high voltage within the panel can cause serious injury or death if you do not take precautions.
