What is quality electrical installation?
Everything always starts with a project. At the beginning, it is extremely necessary to correctly calculate the power used and the load on the network. The planning of electrical wiring must take into account absolutely all the components that make up it:
- all devices and appliances that will be powered by electricity;
- conventional sockets and switches;
- distribution boxes and shield;
- circuit breakers (automatic machines);
- electricity metering devices;
- automated protection;
- sensors, dimmers, etc.
At this stage, the type of wiring is also decided - it should be closed or open. The first method is more affordable, not requiring special equipment. The wires are laid on top of the walls, providing for installation in a corrugation or without a corrugation. If necessary, it will be easy to change the location of the wiring or power supply points. The closed type is the laying of the cable in the cavities of building structures, inside partitions, under a suspended ceiling, in cable channels in the grooves. The features of electrical wiring are also determined, materials are selected, and the cable cross-section is calculated.
Proper electrical installation: how to do it step by step
After creating a project and a diagram of the electrical network, installation work is carried out in the following order:
- Removing old wiring elements from walls, ceilings, columns, etc.
- Marking - marks are made at the places of laying wires and placement of electrical points.
- Construction work - holes are punched in the walls, strobes are formed, etc.
- Laying wiring. Fixing wires during open installation is carried out using special fasteners. During closed installation - in prepared strobes and holes, which are then plastered.
- Installation of an electrical panel. It is carried out in accordance with the requirements of DBN, providing for an external or internal format.
- Installation of sockets, switches, lamps
- Installation of other network elements in accordance with the project.
- Connection of cables, wires and equipment into a single electrical system.
This sequence of installation will allow you to avoid basic mistakes that are often made by inexperienced craftsmen.
After this, commissioning work is carried out. Its purpose is to test how the network will work under voltage. At this point, all construction processes in the room should be completed, and all electrical equipment should be grounded.
Next, sockets and switches are connected, parameters are set, and the protection system is checked. Testing of electrical wiring can be carried out both autonomously and comprehensively. The latter option involves setting up equipment in all operating modes. Safe connection and high-quality functioning of the electrical network will indicate the correct calculation of the load and compliance with installation rules.
If you do not have enough experience in carrying out such work, or doubt your abilities, then it is better to entrust the installation of electrical wiring to experienced specialists. Usually, such companies have all the necessary tools for electrical installation, ensuring efficiency and safety of services. Their biggest advantage is turnkey electrical installation work - a service that is most convenient for most customers.
