What is electrical installation?

Electrical installation works are such types of work aimed at connecting consumers to the power grid, ensuring stable supply of electricity while meeting design parameters. They can be carried out during the construction of new buildings and structures, during reconstruction, or repair of buildings or individual premises. As a result of their implementation, electrical appliances and equipment installed in the building should receive electricity with the required values of voltage, current, power, and operating frequency. It is important to ensure safe operation of the building’s power grid during electrical installation.

Main stages included in the production of electrical installation works:

• Obtaining necessary information about the electrical installation object – conducting measurements, studying existing project documentation, engineering surveys.
• Preparation of the project for internal and external electrical networks based on the received data and requirements of regulatory documentation.
• Selection and supply of components, equipment, and materials for installation to the object.
• Direct execution of electrical installation works, which means laying cable lines, installing and connecting protective, distribution, and other equipment.
• Commissioning. The system is supplied with operating voltage, the operation of connected devices and installations is checked, parameters are monitored. If necessary, defects are corrected, additional adjustments are made.

After successful testing, the installed system is put into operation.

Types of electrical installation

Requirements for electrical installation activities and their composition depend on the type of electrified object, its technical, architectural parameters, types of installed electrical installations or devices, their characteristics.

What types of electrical installation works are there:

• laying internal wiring and external cable lines;
• installation of distribution, protective equipment, electricity meters;
• installation of electrical lighting;
• installation of sockets, switches, breakers;
• installation of power electrical equipment, industrial technological equipment, or installations;
• connection of heating, climate control, ventilation, pumping equipment;
• installation, commissioning of low-voltage systems – all types of alarms, video surveillance, ACS, internet, cable television, etc.

All technical measures related to electrical installation works must be carried out only by specialists who meet qualification requirements and have appropriate permits. At each stage, compliance with all regulatory requirements, including electrical safety and fire safety standards, is mandatory.
