Most (if not all) city codes require outlets be wired with 12 gauge wire and a 20 amp breaker. Lights can be wired with 14 gauge and 15 amps.

One, or possibly a million. The question you need to ask youself is how do you intend to load this 15A circuit. It already has a light on it. Is that all? How much power does this use? What is the usage of these new outlets? How much power do you plan to draw off them?

Remeber power is the product of voltage and current. So your 15A 120V breaker can supply 1800W. Sum up everything you want to put on this circuit. If you plan on drawing more than 1000W regularly on this circuit you should consider using two or more circuits. Keep in mind you want a margin of error (I went with 800W) for large temporary loads such as vacuum cleaners and irons. Don't underrate your circuit, you will regret it later.

Another poster said in another thread that according to code "generally each duplex outlet may count for 180W" (Smseagle). So, to use this rule, you need to take 1800W, subtract the wattage of your security light, and divide the result by the remainder. The quotient, rounded down, is your answer.

Can wall outlets be on a 15amp breaker in the bedroom or do they have to be 20amp?

Technically, they can be on a 15 amp breaker when you use 15 amp outlets. There is a difference. Be sure to check your local code (just call the city building department and tell them you have a code question). some cities require the bedroom outlets to be on an arc-fault breaker.

Is a ground fault indicator outlet installed at the breaker box?

There are tow places to put a Ground Fault Circuit Interrupter. There is a GFCI breaker which would be installed in a breaker box and a GFCI outlet that can be installed anywhere. Most GFCI outlets allow you to connect regular outlets to the GFCI and those outlets will also be protected.

How many 115 volt outlets could you run from a 20 amp breaker?

If you never plug anything into them, there is no limit. If the total current drawn from all outlets exceeds 20 amps, the breaker will trip.

What if lights do not work but outlets work?

You probably blew the breaker for the lights. While usually the lights and outlets in a room are on the same breaker, it isn't always done that way. And you may have blown the light bulbs in the lights.

What size circuit breaker do you need for kichen counter outlets?

Two 20 Amp circuits with the outlets staggered so a different circuit is on two adjacent outlets. Should be GFCI protected.

Where is A GFCI outlet?

Bathrooms, kitchens, garage and outside outlets are typically put on a GFI type breaker. Some electricians use a central GFI breaker that is inside the breaker panel, others use a GFI outlet at one location then "daisy-chain" several outlets to that circuit. Either is acceptable.

If you have 3-4 can lights 1 ceiling fan and 3 outlets what size breaker?

A 15 amp breaker protecting # 14 wire.

How many plugs can you run on a 30a breaker?

You should not run outlets in a home on a 30 amp breaker unless the wiring is 10/2 wiring which is not likely. A home uses either 12/2 wire which requires a 20 amp breaker or 14/2 which requires a 15 amp breaker. If this is in a garage with 10/2 wire and a 30 amp breaker you can easily install a combination of 15 outlets and lights. Really it is the load that counts and not the number of outlets or lights. Add up the load and you will know how many you can install.

How much current should your outlets carry?

Your home electrical wall outlets current capacity is governed by the breaker that feeds that circuit. In most home situations the wall receptacles are fed with a 15 amp breaker. Dedicated outlets could have a higher ampacity as they are installed for specific appliances or devices. To check your circuit, plug a lamp into the outlet. Start flipping the breakers off. When the lamp goes out that is the breaker for that circuit. Look on the handle of the breaker and it will tell you the capacity of that particular circuit.

How many 15 amp outlets on 120 volt circuit?

Depends on the size wire used in the circuit. If you wired the circuit with AWG #12 wire on a 20 amp breaker then you can install no more than 12 outlets. If you wired it with AWG #14 wire on a 15 amp breaker then install no more than 9 outlets. This is assuming only outlets are on the circuit and nothing else.

How many outlets and light can you put on a 15amp circuit breaker?

You should install no more than 9 outlets. If you add a 75 watt light then install no more than 8 outlets and that 1 light.

Plugging an electric heater into a GFI outlet caused the lights and other outlets to go out but didn't trip the circuit breaker why?

A GFCI receptacle can pass it's "protection" to other outlets wired from it. If the GFCI trips, all outlets wired from it will "trip" also. A GFCI tripping will not necessarily trip the circuit breaker in the service panel.

Where can you find a series circuit in your house?

The breaker panel. Breakers are placed in series with all outlets.

How many outlets on a 20amp breaker?

In the United States and in commercial and industrial installations a 20 amp circuit may have 13 outlets, a 15 amp breaker may have 10. In a home there is no limit except common sense. I wouldn't put more than 2 rooms on a circuit. This limits how much goes off when a breaker trips, especially since in homes very often your lights and outlets share circuits.

Can you install a 40 amp breaker for a 30 amp?

No. The breaker must protect the circuit components such as wiring, outlets and switches that are connected to the breaker. Therefore if you have a 30 amp circuit as dictated by its components you need to protect it with a 30 amp or less breaker.

What amp breaker do you need for a run of 10 outlets?

It depends on the use of the 10 outlets. 20 amp is the norm. If this is in a shop with heavy loads then you would have to break them up.

Can you replace a 20 a breaker with a 25 a breaker?

For typical residential house wiring 12 AWG wire is required for a 20 Amp breaker. If you change out the breaker for a 25 A breaker you would have to rewire the circuit with 10 AWG. In that case you could up the breaker to 30 Amps. All outlets and switches should be rated at the same voltage and current as the breaker.

If your circuit breaker popped and will not go back what should you do?

first be sure to reset the breaker handle to the off position. When a breaker trips the handle goes to a neutral position. After resetting the handle turn it tothe on position. If it trips again there is a short in the circuit. Find out which outlets are not workingand unplug anything that is currently plugged in to the outlets. Reset the breaker and turn it to the on position,if it trips again call a qualified electrician.

Does power go to a turned on breaker?

Turning the breaker on allows the power to flow through to the outlets, lights, and appliances on that circuit, so yes power goes to and through a turned on breaker. If the breaker is off, but the main power is on, power still get to the breaker, usually from the bus bar that runs down the middle of the back of the breaker box.

Why would a circuit of electrical outlets not work - the breaker is OK?

Somewhere you have a loose or broken connection.
