For example, bathrooms, kitchens, and garages typically have devices plugged into outlets that draw a lot more than 1. However, bedrooms will likely have lamps and other devices that use much less power so use the worst case scenario when determining how many outlets to put on your 20 amp circuit. Hair dryers and toaster ovens could use up the majority of the 20 amps in the circuit while televisions, computers, and LED lights will use much less.
This chart will give you an idea of how many watts and amps each standard device will use. You can put lights and outlets on the same circuit and doing so can help spread the load between overhead lights which use much less power and outlets which have devices that may draw quite a bit more.
The 12 gauge wire is thicker than a 14 gauge wire and is capable of handling 20 amps of power if being drawn at the same time. Using a thinner 14 gauge wire could result in overheating and possibly a fire.
There are a lot of determinants that play a part in the number of outlets. Frequently, it is recommendable to put ten outlets safely on a amp circuit. But different factors can affect the number and lead to an increase or decrease in the amount.
To have a better understanding of the reasons behind putting ten outlets, let us start from scratch. Amps are the abbreviation of amperes, which is the unit of current. So, amps mentioned on a circuit denote its amp rating. It tells us how much or how many amperes of current can flow through a circuit. So, a amp circuit means that it has the capacity of passing 20 amperes of current through itself safely. The amp rating mentioned on a breaker is also useable for considering the amp rating of the circuit breaker.
Moreover, we can calculate the number of outlets or receptacles on a circuit by using this amp rating. You can select the no. The amp rating of the circuit is also useful in determining the gauge number. For example, a amp electric circuit always works best with a gauge of number 10 or A smaller gauge of number 14 is also available in the market, but it can carry a current load of only 15 amperes. So, it is best to use a gauge wire for better current flow. In case you use a smaller gauge wire like that of 14, it will cause electrical hazards like fire, overheating of circuit, power surge.
It is because the smaller gauge wire is unable to bear the load of current that causes problems. A general rule is that each device on a circuit will draw about 1. The result of Because not all the outlets will be used drawing power. This means a 20 amp circuit should only carry 16 amps at maximum — or about ten devices.
The receptacles in a circuit are your outlets. The switches control the flow of current to an outlet, but they can only control a certain amount of current most are rated for 15 amps.
Your outlets and switches not only need to follow your local and national electrical codes in terms of how many can be installed on a circuit, but also in terms of what devices can be plugged into them.
Both 15 amp and 20 amp outlets are typical in houses, but the difference is important. But you can plug smaller electrical items like lamps and phone chargers into them. It draws less current than the 20 amp outlet is rated for. Light switches are usually rated for 15 amps, which means they can control up to 15 amps of current by switching on or off. How can you tell the difference between a 20 amp outlet and a 15 amp outlet?
All 20 amp-rated outlets have a small, T-shaped slot on one side, while 15 amp outlets do not. The T-shaped slots allow 20 amp plugs or standard 15 amp plugs to fit.
Most households have either a 15 or 20 amp circuit breaker. In bedrooms, there is a general principle where every wall should have an outlet installed. You can also have the same method by putting an outlet for every 6-feet. One amp circuit for all the lighting and outlets for a bedroom will work just fine. My advice is to install outlets within the 20 amp Circuit NEC guidelines and spread them in areas that are easy to reach. First and foremost, a good outlet should follow the local and national electrical codes.
Not only that, but you should also think about what kind of plug your electrical device has. Although both look nearly the same, the 20 amp outlet is distinctive because one side has a T-shaped hole made for amp plugs. On the other hand, amps have two standard plug holes as usual. In most residential areas, you can find a amp and a amp receptacle. The amp outlet is good for the average household accessories such as lamps and chargers, while the amp outlet is best for heavy-duty appliances like power tools in your garage.
