Currently, electricity is necessary for efficient operation at all levels — in our homes we use it to generate light and heat, as well as to power most household appliances. It allows you to perform most of the production processes. A properly constructed electrical installation is required for its use.What is an electrical installation?
There are two different understandings of the term "electrical installation". The first of them, more generally, describes an electrical installation as a network of electrical wires laid in a given building and its surroundings.
In the language of experts, an electrical installation is not only the electrical wiring of a building, but also all connected energy—consuming devices. Electrical installations can be divided into many types based on specific criteria, such as the nature of the building, the purpose of the installation, and how it is performed.Building Characteristics
If, when dividing electrical installations, the type of building in which the installation is to be performed is taken into account, then the installations are distinguished:
Industrial - present in industrial enterprises.
Non-industrial - it is present in non-industrial facilities, for example, in offices, schools, hospitals, as well as in residential buildings.
Agricultural - used in facilities that are part of livestock farms.Using an electrical installation
Another criterion for separating installations is their use. Therefore, we list the installations:
Lighting - that is, designed to connect lighting devices and portable low-power heaters to them.
Power units are designed to power heating appliances, water heaters, and high-power consumers.Type and location of installation
An important criterion for the separation of installations is also the way they are installed in the building. There are installations:
Flush – executed directly under a layer of plaster with a thickness of about 5 mm. The installation is mounted on an unpainted wall, the wires are fixed with wire, nails and staples.
Concealed mounting – the mounting cables are laid in special grooves cut into the wall. Tubes are placed in the slots in advance, into which the wires are then inserted. This solution allows you to replace the installation without forging the wall, but may weaken the bearing capacity of the walls.
Outdoor installation – it is mounted on plaster or on a bare wall, used wherever the appearance of the walls does not matter, for example, in garages and basements. https://cultmoscow.com/vse-obo-vsem/stavki-ks-go-kak-uvelichit-svoi-shansy-na-pobedu/
