Designing electrical wiring in residential premises is an important stage in the creation of an electrical installation, and it must be carried out taking into account safety, ease of use and efficiency. Specialists in the field of electrical engineering and electrical installation, such as electrical technicians or electrical engineers, are usually engaged in the design of the laying. These specialists have the knowledge and experience necessary to create safe and effective electrical installations.
Here are the main steps and aspects of designing electrical wiring in residential premises:
Definition of needs. The first step is to determine the needs of the tenants and their characteristics 
premises It is necessary to decide how many sockets, switches and lighting points are required in each room, as well as what household appliances will be used.
Selection of the distribution device. The switchboard (switchboard) is the central point from which all electric lines depart. At this stage, its location and size, as well as the quantity and type of automatic switches are determined.
Laying of corrugated pipes. Corrugated plastic tubes are often used for laying cables. They can be laid both inside the walls (hidden laying) and on the surface (open laying). The decision depends on the design of the premises and the wishes of the tenants. Recently, split automotive corrugation is increasingly used for wiring https://termousadka.com.ua/product-category/izdeliya-dlya-prokladki-i-izolyacii-kabelya/gofra-avtomobilnaya.html
Placement of sockets and switches. At this stage, the exact location of sockets and switches is determined, taking into account the functionality of the room and the location of the furniture.
Load calculation. The total load that will be connected to the electrical installation is calculated in order to choose the appropriate diameter of wires and automatic switches.
Security account. All safety standards are met, including protection against short circuits, grounding and protection against overloads.
Selection of the type of wires and cables. It is determined what types of wires and cables will be used for each part of the electrical installation, including lighting points, sockets and switches.
Creation of an electrical scheme. An electrical diagram is created, which shows the location of all elements of the electrical installation, the types of wires and cables, as well as the distribution device.
Preparation of documentation. An important part of the design is the preparation of all necessary documents and drawings for the future installation.
Coordination with local authorities. In some cases, it is necessary to obtain permission from local authorities or regulatory organizations to perform electrical installation work.
Installation and testing. After the design is completed, all components of the electrical installation are installed, and then testing is carried out to verify correct operation.
The project of wiring in the apartment can be ordered from professional engineering firms, designers, electricians or specialized interior designers.
The finished project of wiring in the apartment usually includes the following elements:
Wiring diagram: graphic representation of the placement of sockets, switches and lighting points on the plan of the room.
Technical documentation: specifications of cables, sockets, switches and other equipment that will be used, indicating their characteristics.
Scheme consumers: estimation of electrical load and distribution of power in different parts of the premises.
Calculation of grounding and safety: grounding plan and other safety measures to ensure protection against short circuits and current leakage.
Installation and construction instructions: recommendations for electricians and builders on how to install and lay wires.
Estimate and budget: if necessary, calculations of the cost of materials and works can also be specified in the project.
