Often people before starting repairs in an apartment ask for advice on installing the socket boxes in concrete. Some for this work hire professional craftsmen, others try to do the installation themselves. It is believed that this work is difficult to do without special skills. For a successful installation, you need to know what diameter of the socket for concrete is required. It is important to understand what types are and how their installation is different.
Why do I need to carefully choose the installation box?
When choosing a socket for concrete, you need to pay attention to their quality. Equally important is the correct installation of this element. The further operation of outlets in the house, as well as switches, depends on these parameters. If you correctly install the socket under concrete, the switches and sockets will last a long time. If the installation box is not installed correctly, that is, there is a risk of not completely fixing the wires. They can break, as a result, the outlet will need to be repaired.
What are the rosettes made of?
Currently, people most often install hidden wiring in homes. Therefore, when carrying out repairs, the installation of a mounting box is a must.
Basically, modern podrozetniki are made of plastic. In the past, only metal boxes were installed. Polypropylene have several advantages:
- do not give in to corrosion;
- plastic is more convenient to use;
- reliable fixation;
- Do not forget about the dielectric properties of plastic sockets.
What kinds of elements exist?
There are several types:
- Sockets in concrete are installed in the wall. Alabaster, as well as gypsum mortar, are required for their installation. Diamond podrozetniki for concrete are widely used in new buildings. Usually this type is available in standard size. The outer diameter of the socket for concrete does not exceed 68 millimeters, and the distance between the axles is 71 millimeters. The length of the case can be minimal, it is 25 millimeters. The maximum value will be 80 millimeters. Podrozetniki are widespread , the depth of which ranges from 40 to 45 millimeters. This size is used to install many sockets and switches. The advantage of this design is that it is possible to arrange the wires in the form of a loop behind the device. If you need to replace the outlet, the wire is simply unwound from the loop.
- Still there are podrozetniki in concrete with two connecting knots or without them at all.
- Mounting boxes for installation in a drywall. They are attached quite simply with the help of spreader legs. If you want to put several outlets, then the wizards advise using special blocks. They already have the right amount of these elements. It is better to decide on the size of concrete sockets for concrete in advance. This will help to avoid errors in the future.
Can I purchase universal mounting boxes?
In the assortment of many construction stores, one can often find universal mounting boxes. The description says that they can be installed both in a concrete wall and in plasterboard. If you plan to use this device as a socket for concrete, then you will need to first remove the spacer legs.
How to mark before installation?
Marking is an important step before starting work. You need to have a clear idea of where the sockets and switches will be in the house. You must select their number. When choosing, one should proceed from the convenience of residents and interior design. Once you have decided on all the parameters, you need to go to the elevation mark, the location of sockets and switches using a tape measure and pencil. You can also use the ruler.
Most often, in residential premises, sockets are placed no lower than 30 centimeters from the floor. Switches must be mounted at a height of 90 centimeters from the floor. These parameters are considered generally accepted. This arrangement is convenient to operate.
How to indent before installing a switch and socket?
The switch is usually placed at a distance of not less than ten centimeters from the edge of the box. In the kitchen, the outlet can be installed no lower than 15 centimeters from the countertop.
After the person has decided on the place of the future outlet, you need to make a mark on the wall with a pencil. A mark appears on the wall that exactly matches the center of the socket. From this point you need to draw two lines. They go at a right angle. The lines should divide the plane into horizontal and vertical. This technique can significantly save time when installing the socket. The main task is to carry out the installation correctly, because then gypsum mortar or alabaster will be used. In this case, it will be difficult to correct the errors.
How to drill a rosette?
There are several ways to make a hole:
- You can apply a crown on concrete under the socket. This method is distinguished by its effectiveness. If a person wants to use this method, then he needs to purchase special crowns for concrete. They include victorious teeth. Their diameter is 70 millimeters. Crowns are ideally suited for drilling sockets, experts say. To easily remove concrete, you need to use a special winning tip. Professionals advise pre-making the hole with a conventional drill, and then expand it with special tips. The result is a hole with a depth of five to seven centimeters. When choosing a drill, you should pay attention to the diameter. Better to choose tips from six to eight millimeters in size. But most often they use diamond crowns for concrete for the socket. They are the most effective and reliable.
- It is permissible to use a hammer drill. In addition, you can use an ordinary drill. This method is considered the most difficult. Usually they resort to it to install one outlet. With such a need, there is no need to buy special crowns. To correctly install the mounting box in the selected way, you must first attach it to the wall. The selected place must be circled with a pencil. Drill on concrete, you need to make a hole in the center. After that, the perimeter of the circle is drilled. For further work you will need a chisel. They need to remove concrete from the resulting niche. After this work, it is possible to install a socket.
- You can do the work with an angle grinder. This method is considered the easiest. The disadvantage of this method is that a large amount of construction dust is emitted. Do not use too large a disc, which can harm the surface of the wall, because it can cut off an extra piece. Then there will be a need to putty the surface.
How to lay the wire in the socket?
Before starting work, you must turn off the electricity in the apartment. Be sure to check how the ends of the wires are insulated. You will need to make the strobus small. Through it, you need to run the wire so that it appears in the future socket. It is not necessary for the strobah to “stoke” strongly in the wall; it is important to make a bevel relative to the niche. A hole must be made in the mounting box. This will require a construction knife. Typically, mounting boxes already have blanks for future openings. Masters advise making holes in the back of the box. This arrangement of holes makes it easy to connect the outlet. The switch is connected in the same way.
When the cable enters the installation box, remove the top insulation. Separate cable cores are exempted. Usually, they connect to the desired terminals. After carrying out the work, you need to firmly fix the socket.
On this installation work is completed. As you can see, you can install a socket box with your own hands, but for this you need to clearly follow the instructions.
