Electrical work: technological sequence and features

To competently perform the work on the installation of electrical appliances and lighting, you need to have both theoretical training and practical skills in the field of electrical wiring. The sequence of specific actions for electrical installation work, described in this material, is corrected and supplemented according to the specifics and conditions for performing specific types of repair and construction works. With all the variety of techniques and techniques used in the electrical installation industry, it is rather difficult to collect and organize them into a single methodology. Despite the existence of an extensive theoretical base of instruments used in conducting electrical work, there is a more or less universal algorithm for the most frequently repeated actions that makes the electrical installation industry more ordered and capacious.

As a rule, start electrical work from the device niches, openings, holes, furrows and sockets for mounting electrical equipment and laying routes of wires. It is understood that the completion and procurement of mortgages and fasteners by this time the electrical engineer has already been carried out in accordance with established standards and technical safety requirements. Further, the marking of the points of installation of luminaires, switches, devices, plug-in sockets of apparatuses, shields and other electrical appliances is usually made. With concealed wiring, these actions in the premises are carried out before the plastering and trowelling works, and with open wiring - after them. If major repairs or the construction of new buildings are underway, installation of ballasts, shields, switchboards and other supporting structures and devices may be necessary.

In order to carry out the next set of electrical work, it is necessary first to make corrections, measuring and cutting cables and wires, preparing and processing the ends of the cores and their connection according to the element schemes with the necessary isolation, marking the finished parts of the electrical wiring and folding them into coils. After that, the wiring specialist pierces the furrows and drills the nests to install fasteners, staples, boxes and other parts of the concealed and open wiring. Where an installation of open wiring is planned, the described actions are usually performed after plastering and trowelling, and in the case of concealed wiring - in advance. After that, they proceed to installation of branch boxes for switches and sockets, pipes, fasteners, brackets and podrozetnikov (with open wiring).

The next complex of electrical installation works, as a rule, begins with the reconciliation, installation and then fixing devices, instruments, electrical equipment, laying cables, wires and ready-made parts of postings on the basis of the workpiece. These actions in the premises are made after the trowel and plaster works have been completed and before the painting starts, if a concealed wiring is planned. As a result, installation of switches, sockets, lamps and other apparatuses and devices is carried out, as well as the connection of different parts of the wirings into a single circuit. Wall switches or switches are most often installed at doors at an altitude of 1.3-1.7 m. Electrical installation work is carried out in accordance with the specified design decisions, the total estimate of construction and repair work, as well as the specifications of the materials used and installed electrical appliances.

The considered algorithm of work on the organization and conduct of electrical work demonstrates the orientation mechanism of actions, but it is not a template or the only possible and has some key advantages over the rest and alternative options. With the development and improvement of modern lighting and power supply technologies, the classical scheme of installing hidden and open wiring, installing various devices and devices is gradually supplemented with new and more progressive technologies and techniques in the field of electrical installation and other construction and repair work.
