How to install multiple outlets on one circuit

Your question is phrased incorrectly. You can put as many outlets as you like on the single 30 amp breaker so long as whatever you plug into those outlets does not exceed a combined 30 amps. That is technically. In other words, do not exceed a combined 18 amps with your appliances. In a residential application, each volt outlet would need its own circut and circuit breaker.

Usually these outlets are designed and controlled so that only 1 or 2 machines will ever be on at the same time. Also, the access to these outlets is restricted to trained maint staff. Here it is recommended one per breaker. I am not certain if that is due to the electrical building code or common sense however. Some appliances can use 30 amps, most are smaller than 4amps, the transformer might not handle that much though.

I'm not sure if i need to install a separate 30amp breaker for every v outlet. Answer Save. Fixit Lv 4. It depends what you use them for. How do you think about the answers?

July 15, at am.Just to clarify, a common line with several outlets is always wired up in parallel since there wouldn't be any current flow through an outlet with something plugged into each outlet to complete the circuit, and even then, the line voltage would be divided reduced between each outlet, rendering the whole line inoperational.

So what this refers to is rather a series of outlets along one common power line, but wired in parallel to it. You do need to have some basic confidence in working with electricity, but this is essentially a job for a novice. Besides that, all you need is some electrical wire. Before working with anything electrical, make sure that the power to the area is off.

You can check by using a multimeter on the outlet to see if there is any current there. Disconnect the hot, neutral and ground wires from the first outlet, but leave them in the box. Now you need to run a length of wire from the second outlet to the first. In new construction this is easy. Drill holes in the studs and run the wire from outlet to outlet through those.

With older construction, you have no option but to take out some of the drywall in order to do this. There will be a small knockout plate on the side of each box. Knock this out with a screwdriver. Allow about 8 inches of wires in each of the boxes and then cut the ends with a knife.

These are short lengths of wire. Cut three of them, one for the hot, one for the neutral, and one for the ground wires. They only need to be a few inches long. You can now wire the second outlet. Cut 4 inches of the sheath off the wire in the junction box. Connect the end of the hot black wire to the brass terminal. Screw the end of the neutral wire to the silver terminal. Finally, screw the ground or green wire to the metal screw in the box.Electrical receptacles have two pairs of terminals so that you can daisy-chain multiple receptacles on a single circuit in an existing house.

Installing too many receptacles on a circuit presents the probability of overloading the breaker, however, so a prudent approach is to distribute the receptacles among two or more circuits, particularly when adding multiple outlets in a single room. That way, if one of the breakers blows, you'll still have a live outlet to use.

Standard electric code allows you to wire amp receptacles with gauge wire, but it's safer to use gauge, which is thicker. Turn off the power supply before working on the electrical project.

Install an electrical box for each outlet you want to add. Using an old work, or remodeling box, allows you to avoid removing wall covering to nail the box to a stud. Locate the studs with a stud finder and place the box somewhere between two of them.

It can be any distance above the floor that is convenient. Trace the outline of the back of the box on the drywall with a pencil and cut out the hole with a drywall saw. Feed the cables you need for wiring the receptacle to each of the holes. Establish a series of receptacles for each circuit and run the power cable to the first one in the series. Run a second cable from that receptacle to the second in the series, a third cable from that one to the third, and so on.

Run the power cable to point where it connects to power, but don't connect it yet. Feed the cables for each receptacle through the back of the old work box, pull out about 6 inches of slack, then push the box into the hole and anchor it to the drywall by turning the screws in front with a Phillips screwdriver.

Distinguish the wires between the incoming, live one and the outgoing one supplying power to another receptacle. Wrap the incoming wires around the top pair of terminals on the receptacle with pliers. Connect the black wire to the brass terminal and the white wire to the silver one. Tighten the terminal screws with a screwdriver. Connect the outgoing wires to the other pair of terminals in the same way. Twist the bare ground wires together and wrap them around the green ground terminal.

Push each receptacle into the box after you're finished wiring it and screw it in place. Screw on a cover plate with a flathead screwdriver. Connect the power cable to the power source, which might be a breaker in the panel or a device on another circuit, after you've installed all the receptacles.

How to Wire Two Separate Switches & Lights Using the Same Power Source

You can daisy-chain a GFI just like a regular receptacle, with one difference. The incoming wires must connect to the "line" terminals while the outgoing wires must connect to "load. Warning Don't reverse the polarity of a receptacle by connecting the wires to the wrong terminals.The circuit breakers in the electrical panel in your house are safety devices.

Each one is designed to disconnect power when the current passing through the circuit exceeds its rating. This prevents overheated wires, electrical power surges and fires.

Electrical outlets don't draw power until you plug something in, so a amp circuit should theoretically be able to handle as many outlets as you want without overloading the breaker. There are practical limits, though. The National Electrical Code doesn't limit the number of receptacles you can place on a amp circuit, but you'll overload the breaker if you run appliances that draw more current than the breaker can handle.

The NEC does specify that a circuit breaker shouldn't handle more than 80 percent of the load for which it is rated unless the breaker is labeled otherwise. By this standard, the total current draw on a amp circuit shouldn't exceed 16 amps. This allows the breaker to handle the temporary surge that happens when an appliance such as a power saw or air conditioner starts up.

When deciding how many receptacles to add to a amp circuit, consider what you are likely to plug into each one. For safety, the total draw on the circuit shouldn't exceed 16 amps at any one time, which translates to a maximum power draw of 1, watts on a conventional volt circuit, even though the breaker won't trip until the power draw exceeds 2, watts.

You should limit the number of receptacles on a circuit that will handle a power-hungry appliance. For example, most electric heaters draw 1, watts, so a circuit that powers one should have few other receptacles.

How to Wire Multiple Outlets

To better distribute the power consumption among all the breakers in the panel, combine lights and electrical outlets on a single circuit, because lights typically draw less power than appliances.

Your kitchen must have at least two outlets, each on separate circuits, so that if one breaker trips, you still have power. Adding lights to each circuit balances the load and avoids the necessity for separate lighting circuits. Certain kitchen appliances, however, such as the dishwasher, must be on a dedicated circuit, which means that you can't include anything else on the circuit -- not even lights.

In most circuits, only one outlet is likely to be in use at any one time, so it's a good strategy to spread as many as possible around the house on a single circuit to guarantee you have power where you need it. One rule of thumb is to assign a maximum draw of 1. You must use gauge wire to connect amp circuits; when you're installing receptacles in the bathroom, kitchen, laundry room or outdoors, they must generally be ground fault interrupting receptacles.

It only takes a minute to sign up. In my rebuilding project I have counted 18 outlets and lights on one bedroom circuit that travels through 3 rooms. Is that ok?

Also, check your breaker. For example, don't expect to run an electric chainsaw and a vacuum at the same time off a single 15A circuit. If you have a 15A breaker attached which is likely the case, I would recommend not running any major appliances Such as a Microwave or Window AC unit off of it, since that will take up most of your juice, and one too many lamps in the other 17 outlets could trip your breaker. If you need to run a heavy appliance, just wire in another circuit, and don't drill a hole through the wires near the breaker box Voice of experience.

Depends where you are and for what value of OK you are looking. So long as the breaker is 15 amps it should be "safe. Other people have mentioned some inspectors in the US having an expectation of "around 7" but I don't think code was ever found to support that, other than the code of "do what it takes to get the inspector off your back.

Personally, I'd break it up, and separate lighting from outlets I detest being left in the dark when something plugged into an outlet causes a trip.

How to Wire Outlets and Lights for a Room

However, if the bulk of what is happening at the outlets is "nothing" or "wall-wart for a phone" or basically if you don't trip it much, you COULD leave it alone. It's certainly going to be cheaper to do nothing. Without knowing how many devices were lights. But I have a particular philosophy, and there's no code requirement to do it my way. Breakers are there for when a peice of equipment is faulty or someone violates the assumptions that went into the installation.

They are not there to limit load in normal use. This means you need to think about what loads are likely to be used where. Especially if you live in a place with relatively low power socket circuits from the terminology you use i'm guessing you are in america.

From a compliance perspective it's going to depend on where you live. Others leave it to the judgement of the installer. That's not dangerous, or illegal code-wise possiblyand it is ok to have that. But I must say, in all of the units I service, I havn't seen that many outlets on one circuit. If anything, I'd say to run a tv or two, maybe a game console or two as well since they hardly draw any amperage.

Usually I see at most outlets per circuit on 20 amp breakers. But there's nothing wrong with your setup. Just watch for high-demand electronics or heaters on that one circuit. I've always been told that it's 8 for a 15A circuit and 10 for a 20A circuit. Count the light as one of those as well.

So it would be 7 outlets and 1 light fixture. But exercise common sense as this all depends on what you plan to plug into them. If you know for a fact you are are going to plug in stuff that draws a lot of power, like a window AC unit, consider putting that on a separate circuit.

There are some assumptions that were missed in this discussion, so I will point out the missing questions by listing them here. It looks like there was too few funds or not enough talent to actually design a SAFE and good working electrical system in your home.

I was actually searching for a nice schematic for a 4 way switch to 19 LED recessed ceiling lights so I could share that with a co worker who is just starting out and is eager to learn. GFCI not installed correctly or not at all in the "best locations" Yes, its creative Yes, it is sexy looking so tightWhen an outlet receptacle falls in the middle of a circuit run rather than at the end, there are generally two cables in the outlet box. One cable is the incoming power source entering the box from one side, while a second cable exits the box to continue onward to "downstream" locations on the circuit.

There may also be a third cable if the circuit is branching in two directions at this point. First, the circuit can be direct-wired through the receptacle—that is, the entry cable can be attached to one pair of hot and neutral screw terminals on the receptacle, while the exit cable can be attached to the other set of screws.

In this configuration, the circuit flows through the receptacle at all times, using the connecting tabs on the receptacle to establish the continuous circuit path.

The second method of wiring a mid-run receptacle is to connect the receptacle to the circuit wires with pigtails that tap into the circuit wires passing through the box.

In this case, the circuit load flows both to the receptacle and to any "downstream" receptacles without being dependent on flowing through the receptacle's connecting tab. Both methods are acceptable by Code, but pigtailing is preferred for several reasons. With two cables in an electrical box, one is the incoming power feed or "line" cable and one is the outgoing power or "load" cable. On a standard volt receptacle, there are three types of screw terminals: brass-colored screws that accept black hot circuit wires, silver-colored screw terminals that accept white neutral wires, and a green screw terminal that accepts the bare copper grounding wires.

Be aware that in old wiring, you may not see the familiar black and white jackets on the circuit wires—the important thing to remember is that brass screws accept hot wires, and white wires accept neutrals. It's also possible that in some configurations, a hot wire may be indicated by red insulation on the wire jacket.

To direct-wire through the receptacle, connect one of the black hot circuit wires to one of the brass-colored terminals, and connect the other black wire to the other brass terminal. Similarly, each white neutral wire is connected to a silver neutral terminal. These need to be twisted together with one or two pigtail wires joined with a wire connector.

One ground pigtail connects to the green ground screw terminal on the receptacle. If the electrical box is metal, you also need a second pigtail to connect to the ground terminal on the box itself. Usually, this ground terminal is a green screw threaded into the back of the metal box, but it is also acceptable by code to make this connection with a green clip that attaches to the side of the box. Some receptacles also have holes in the back of the receptacle body, used for "back-wiring.

The push-in type of connector is unreliable and can lead to loose wires and other hazards. Professionals almost never use the push-in connectors on devices.

To connect the receptacle with pigtails, each of the black, white, and ground wires in the two cables in the box are joined together with a short length of wire called a pigtail.

The other end of the hot pigtail connects to one of the hot brass terminals on the receptacle. Again, if the box is metal, you need an additional ground pigtail connecting to the box terminal. With this method, only three wires are connected to the receptacle, as opposed to five wires with the direct wiring method.

Any problem with the receptacle, or even a loose wire under one of the screw terminals, could cause you to lose power to the downstream circuit receptacles, as well. Even diagnosing the problem can be difficult, because if all receptacles lose power, it's hard to determine which one is causing the issue. Direct wiring also complicates repair or replacement, because if you have to take one receptacle out of the circuit, you interrupt the remaining downstream receptacles.

The receptacle must be reconnected before the circuit downstream can function again, leaving the circuit out of commission in the meantime.
