Internal sockets: description and types. How to install internal sockets

Doing repairs in the room, people try to achieve aesthetics. To not spoil the design, but to get a functional room, use internal sockets. In addition, they are more aesthetic, they are also safe and convenient to operate. It is worth knowing what kinds of elements exist, what advantages they have.

General characteristics of the internal socket

The socket for indoor installation is more popular than the device for open installation. This can be explained by the high level of security that it provides. Use it mainly with hidden wiring. During installation, this outlet requires cutting out the installation space in the wall. If the wall is made of plasterboard, then there will be no problems with the hole making. And in the case of concrete or brick partitions, some effort will have to be made to achieve the desired result. Among the advantages that distinguish internal sockets, you can distinguish aesthetic appearance. The device literally sinks to the inside of the wall - only the outer part remains on the surface. The downside of these devices is some difficulties in the installation process. They can arise in wooden houses.

Hidden sockets and switches: features and classification

All existing electrical sockets for design features can be divided into devices for open wiring and for concealed. The first option is resorted only when a temporary outlet is needed. The dangerous part of the device is in a plastic casing and is attached to the wall. Often these devices have a special backlight for the frame, a protective cover, a timer to turn off, protection from children. Internal sockets are only used with concealed wiring.

The whole main part of the device is located in the wall. Outside, only the panel is fixed, where the plug will be inserted. The latter, in turn, is pressed by a special spring-loaded part and a stubborn system.

Earthing

The electrical circuit distinguishes products with and without ground. An internal socket with grounding has in the design a special element, which is connected to the grounding wire. This type of instrument is recommended to be installed in rooms with high humidity. However, it is not uncommon for a ground wire to be missing.

Internal electrical outlets of this type are distinguished by the presence of a socket for the pins that are responsible for connecting the "zero" before the electricity supply starts. They are recommended to be used with powerful consumers. A socket for flush mounting without a grounding element is a two-contact model. These devices are used in the event that the wiring in the apartment is only two-wire, and there is simply no grounding capacity.

Protection against moisture

By the type of protection against moisture all electrical appliances (sockets and switches) are divided into standard devices and with an increased level of protection against moisture. The first have long and successfully been used in rooms with a normal level of humidity, and the function of moisture protection is completely absent here.

Internal sockets with special protection are used in conditions of high humidity. It is an ideal choice for saunas, bathrooms, kitchens. This product is characterized by the presence of a special membrane of rubber and dense rubber rings. They protect the device from moisture and water. Plastic covers help to remove condensate or water from the surface of the outlet. On some especially protected devices there is also an additional cover, the task of which is to prevent the ingress of moisture inside.

Number of pads

By the number of pads, the electrical outlets can be single, double or triple. Single is distinguished by the presence of only one jack for connecting the consumer, while the rest is two and three. Multiple devices are more often found in kitchens, offices or any other premises where a large number of consumers need to be connected. On sale it is possible to meet internal sockets with the switch. Previously, such were only in Europe. Today they are successfully used in our country. This is a convenient solution that connects at the level of a person's lowered arm.

IP44 socket and marking of hidden outlets

All electrical appliances are classified according to the level of safety. So, on sockets or switches, you can see the marking in the form of letters IP and numbers. Here it means the level of protection of the device from various external influences.

The number (in this case "4") means that the device can withstand the impact of dust and other objects, the size of which is not more than 1 mm. The second digit indicates how much the device is protected from moisture. All those products that are sold in stores and labeled IP44, reliably protected from water and can even carry open spray. Internal outlets of such a plan are the most common today in our country and in Europe. They have optimum performance for installation in all types of rooms.

Where can I install such outlets?

You can mount such elements almost everywhere. This type of outlet is suitable for installation in bedrooms, children's rooms, bathrooms and kitchens. They are well protected, and the operation of those is completely safe. On sale there are even solutions with protection from children in the form of an additional casing, rubber gasket and lid. But with all the safety for a person it is not recommended to install these devices in garages, on the vestibule sides of the walls of houses, at car washes and wherever there are risks of water ingress into the outlet.

Sockets for the Internet

Along with electric, there are also low-voltage sockets for computer networks. This is a very convenient solution for both home and office. With such devices, you can forget about the bundles of cables that are stretching on the floor.

The cord usually hides inside the wall, and computers and other equipment are connected to the network through this very power element. Installed socket RJ-45 internal is quite simple. You need to make a niche in the wall, then separate the cable (twisted pair) and connect the wires in colors with the contacts on the socket. After this, it is necessary to fix everything securely and tightly close the outer cover.

Recommendations for correct installation

Correctly executed installation of an electrical outlet is a guarantee of safety, long and convenient operation of electrical appliances, which will be fed from it in the future. Therefore, before installing, you need to know some rules. The optimum installation height for a standard apartment or house should be 300-800 mm from the floor surface.

Of course, there are also sockets that are installed above the baseboard, but this is most likely an exception. If the element has a grounding contact, then the installation of the inner receptacle must be carried out at a distance not less than 500 mm from gas lines or heating appliances. If children live at home, then it is better to set a point higher than it is supposed to and is specified in the standards. The installation of a double or single outlet must be carried out in the same box. When it is necessary to install several devices that will be located next to each other, it is better to use two-bollards boxes. They will be connected together after the end of the work. Such fastenings are usually carried out using loops. The contacts of the previous socket are docked with the following.

Installation instructions

First of all, the room is disconnected from the electrical network. Next, the installation site is determined. Then, using a drill, a perforator or a hammer, make a hole in the wall. It is desirable that the edges of the recess are as flat as possible. After installing a plastic box, where will be the wires and the entire inside of the outlet. At the bottom of it there are two holes. In them, the conductors of the electrical wire must be located. To fix the podrozetnik, you can use plaster mixes, glues on a gypsum base or gypsum. The process consists in lubricating the solution with any slots. It is best if the material looks like a soft clay by its consistency. Then remove the remnants of the solution and level the wall. The wire must be secured in the box. After that, the cable is peeled off approximately 2 centimeters and fixed on the contacts of the socket of the socket. First, the zero conductors of the cable are connected, then the phase conductors, and then the grounding. The process of fixing the wires is done with screws or springs. Then the shoe is attached to the jar. This can be done with the help of sliding paws or self-tapping screws, which will pass through the entire surface of the socket and junket. Then it remains only to install the plastic case and check the operability of the device.

Conclusion

So, we found out what the internal sockets are. As you can see, this is a great way to hide the unnecessary looking elements. But they should be installed according to the safety rules at the recommended height.
