History of the profession

The profession of electrician appeared relatively recently. At the end of the nineteenth century, the first power plants began to appear and networks were laid. It was at this moment that the need arose for personnel who could service these stations. With the development of electrical networks and the construction of more and more new stations, there is a demand for specialists in the electrical power industry.

Currently, electricians are required in almost every enterprise. Organizations that service apartment buildings have an electrician on their staff who is responsible for intra-building networks. Due to the prevalence of the profession and the difficult work, quite high demands are placed on specialists.
