All companies that plan, construct, operate, or maintain electrical installations are well advised to appoint a responsible electrical specialist according to DIN VDE 1000-10 or an electrical system operator according to DIN VDE 0105-100. However, in practice, it is often the case that the entrepreneur and upper management are not electrical specialists themselves and therefore cannot take on the tasks and responsibilities in the field of electrical engineering. The solution for this situation is a well-thought-out organization of the electrical sector with a responsible electrical specialist or electrical system operator, who is then entrusted by the entrepreneur with the technical management of the electrical operation or part of the operation. The necessity to have one or more responsible functions, depending on the size of the company, remains.
