One of the important things in the construction of all kinds of residential and commercial buildings is the principles of their electrical wiring. To implement a safe electrical system, a series of requirements are needed that must be carefully checked before purchasing the necessary equipment and also calculating the costs.
Building Electricity Standards
In electrical work, a series of standards must be followed during work. For example, the location of the switch and socket should be carefully determined. For electrical appliances such as washing machines, refrigerators, packages, microwaves, etc., the location of the electrical outlet is very important. Usually, the electrical outlet of these devices is installed at a low height. The distance between the switch and the electrical outlet should be in standard mode. The distance of the power switch from the floor of the building should be at least 110 to 120 cm. If the electrical switch is installed at the entrance of a room, its distance from the frame should be 15 to 25 cm.
An important thing that should be considered in building electrification system standards is the proper selection of electrical wires. In other words, for each electrical device, a specific type of electrical wire and cable is required in a specific size. For example, for lamp and lighting system wires, the cross section of the wire should be around 1.5 to 4 mm square; Or in the case of devices such as air conditioners, a wire with a size of 4 square millimeters is required.
Types of electrical services
Installation and commissioning of electrical appliances, repairs of building wires and cables, repairs of all types of electrical devices, electrification of new buildings, industrial wiring, installation of fuses and electricity meters, etc., are among the most important electrical services. In general, it should be said that all electrical works, wiring and installation of electric wires and cables should be done by skilled and specialized people in reliable centers.
Electrical methods
Electrification of the building requires the implementation of several steps. To start the work, a complete map of all parts of the building must be prepared. The exact location of wires, cables, switches and sockets should be carefully checked. Then proceed to install special pipes for the passage of electric wires. Power cables must be passed through the meter and fuse. All safety precautions must be observed during the electrical work. Electrical services include the installation and operation of a complete electrical system or the repair of all types of electrical appliances.
Electrical works in all types of buildings are carried out in different ways. Electrification may be done in the form of built-in, surface (surface) and ground. In built-in electrical work, after the building plan is carefully checked and the exact location of the cables, switches and sockets is determined, the grooving operation begins. These grooves are the place to install plastic pipes for electric wires. After finishing the work, the groove is covered with materials.
In surface electrification, the pipes intended for the passage of electrical wires are connected to the ceiling or wall by fasteners. The packages must be secured in place by means of plate rolls and screws. If metal pipes are used for electrification, special steel screws must be used. For this electrification model, nails should never be used to secure pipes, wires or even distribution boxes. If the roof is of a false type and we want to carry out surface electrification on it, the pipes must be passed through the main ceiling and not through the false ceiling.
Another method of electrification is to install cables on the ground. In some cases, it is necessary to pass the power cable under the road or under the ground. In this case, a protective tube is installed in place. Of course, it should be noted that before installing the pipes, the mechanics of the soil should be fully checked.
