Wiring electricians by sex is used only in newly under construction buildings. This method of electrification of the room is becoming increasingly popular among residential property owners, as it is characterized by better security compared to the usual way. In addition, it is significantly economical, and the performance of work does not represent much difficulty.
Pluses and minuses of sexual wiring
Laying cable by floor, you will not spoil walls and shoals
Taking a decision on the laying of an electrical cable in the floor, the developers are guided by the positive characteristics of this method:
- Explicit safety advantages compared to the wall laying, as it is possible to avoid accidental damage to the cable when climbing nails, dowels, drilling holes.
- Significant savings when purchasing an electric cable. Its quantitative need is significantly lower than with the usual wall laying method.
- The simplicity of work does not require special qualifications. The most difficult thing is to lay a cable in a corrugated or other pipe.
- Connecting boxes are located at the wall or in the wall, immediately above the floor level, therefore the risk of accidental damage to the cable is excluded.
- There is no need to stick the walls or applying a thickened layer of plaster to close the wiring.
Check if the cable in the pipe is moving freely
The negative parties to choose such a method of laying electrical storage can be attributed:
- The complexity of the repair work and replacing the electrical wire if necessary. So, when the chain breaks for various reasons, it will be impossible to find a problem area under the floor, so you have to completely pull out the cable and replace it with a new one. That is why when the cable is wiring in the floor, you must follow the rules and recommendations for its installation: the pipe cable must move freely. Before pulling out the cable, taking it in one end of the wire, to the second end it is to attach a strong rope or a soft wire, which will allow you to draw a new cable in place for the previous one.
- Additional financial costs for the acquisition of corrugations, because the walls of the cable fit into the shoes or simply close the layer of plaster.
After studying all the positive and negative sides of the gasket of the electrical cable, each owner of the room will take its solution: what is better - wiring in the floor or the usual way - in the wall.
Some features
By making a decision in favor of the Fashion Electrician, it should be borne in mind that when performing work, it is necessary to comply with the requirements established by the rules of the electrical installation devices, according to which the connections and branches of the wires should be available to specialists for inspection and repair work.

Corrugated tube will save the wires from deformation
In addition, the locations of connections and branches of the wire should not have a mechanical tension force. It is possible to avoid this by placing an electrical cable into a metal, corrugated or polyethylene tube, which takes on the entire load of the flooring, and the cable will remain free from the tension, and the free stock of the wire will be provided.
Junction box can be mounted in the wall
PUE requirements oblige to install junction boxes that cannot be equipped under the floor. However, with this situation there is a way out: place junction boxes in the wall. At what level from the floor? On that will ensure safety from flooding and will not lead to free access from children.
Since the corrugated pipe used for the installation of electricity must have a smooth inner surface, it is often replaced by applying a polyethylene tube of the desired diameter for this. About how to make wiring on the floor with your own hands, see this video:
The table shows examples of technical data of polyethylene pipes that can be used to mount wiring in the floor:
| Outer diameter in mm | Wall thicknesses in mm | ||||||
|---|---|---|---|---|---|---|---|

What pipe will be better and more affordable in financial plan: metal, corrugated and plastic - decides each independently.
Montaja rules
The length of the cable on the track should not exceed 20 m
To conduct wiring in the floors, it is necessary to take into account certain norms and recommendations of specialists. They are as follows:
- By mounting the track with an electrical cable, it should be placed in a corrugated sleeve or a pipe from another material. If this is not done, if it is necessary to replace it, this operation will be impossible.
- The cable laid in the track that will be covered with finishing sex, should not have twisting wires. Ends should be displayed in junction boxes.
- The wire in the corrugation or other pipe should take no more than 40% of the entire space. This will provide the ability to replace the cable if there is a need.
- The optimal cable length on one track should not exceed 20 meters. At the same time, the cable wiring in the floor should not have steep turns and changes to the direction under an acute and direct angle.
- If the track is paired during the wooden floor, it should not pass on top of the lag. To do this, it is necessary to make technological holes and process wood with special means that prevent fire. The pipe will be securely kept in the holes, so the additional attachment will not need.
- With a concrete base for sexual coating, the thickness of the screed over the corrugations must be more than 3 cm.
- The crossing of the tracks should be avoided, as this will automatically lead to an increase in the thickness of the screed. Mounting tips under the floor, see this video:
