One of the important and sensitive things in building construction that must be done according to certain principles is electrical wiring. Wiring work must be done according to wiring standards, because any negligence in this work can lead to irreparable financial and life losses. In addition to electrical wiring, special wiring must be done for landline telephones, which are usually 4-strand foiled wires. One of the issues that must be considered in wiring standards is that To be done with the help of a standard map prepared by electrical engineers. But before designing the wiring plan, issues such as construction type, building infrastructure, roof model, wall construction type, floor construction type, etc. should be considered. Also, among other factors affecting wiring standards, we can mention the distance and location of socket switches, the building's fuse capacity, the cross-sectional area of the required wires, etc.
The building's wiring standards
Certain standards have been defined for wiring in buildings that you should pay attention to and comply with. These specific standards are:
All wiring inside the building, both surface and built-in, must be passed through special wiring pipes or trackings.
The size of the inner diameter of the pipe compared to the handle. The wire should be 1.3 in minimum.
The pipes during the building electricity piping should be empty at the time of installation, and the wires and cables should be placed inside them after the piping is completed.
The circuits that are placed under the floors must be implemented using steel or plastic pipes.
The pipe clamps in the surface wiring must be of the double screw type so that the pipe does not have contact with the wall or ceiling and At least, it should have a distance of 6 mm.
There should not be more than four 90 degree bends along any section of piping that is located between distribution boxes or similar equipment. The pipes should be cut with the help of a saw and its sharp parts should be smoothed.
It is not allowed to change the type of pipe without putting some kind of box in the place of its change.
Connecting piping to vibration devices. Like the motor, it should be made using flexible steel pipes with a suitable bushing, which should be at least 20 cm long.
The wires used in the wiring should be up to 10 square millimeters of single wire type with insulation. be PVC.
Connections and impregnations should be done with the help of screw terminals.
It is not recommended to carry out exposed wiring using multi-layer wires such as plastic straps, nail fasteners.

Different methods of building electrical wiring
Roofed wiring
In roofed wiring, all the wires are embedded and installed on the outer part of the walls. Also, in the usual case, in order to make the wires look better and prevent other problems, the wires are passed through special pipes or white ducts. This is done to make the wiring process more orderly. Of course, it can be said that compared to built-in wiring, exposed wiring has a more messy appearance and spoils the appearance of the building, although exposed wiring also has its own advantages, for example, the maintenance and repair of wires and the access of the repairman to the wires in this model is better than The wiring model is built-in.
Built-in wiring
In built-in wiring, no type of wire can be seen in the appearance of the facade, and it is necessary to complete the work of the built-in wiring before constructing the facade of the building and then proceed. Facade the building. Also, most of the time, in this wiring model, just like surface wiring, in order to increase the order of the wires and increase their protection, the wires are passed through special pipes or white ducts. The biggest issue and problem with built-in wiring is that if you need to repair or replace the building's wiring, you have to completely demolish the walls of the related sections in order to access the wires.
Wiring the building is considered a specialized work that requires high experience and expertise, that's why we suggest you do the wiring of the building with the help of expert and technical people. Also, as we said, the use of electrical panels in building wiring has its own importance and advantages, that's why it is recommended to use this device
