The paper proposes a method of calculation and rapid sizing of power circuits of electrical panels using a program made in-house. The proposed application has a friendly and very intuitive graphical interface, being easy to use due to the intelligent way of making the selection and data entry. This application emerged in response to the real need for fast and accurate sizing of low voltage electrical switchboards used in industry. The real help is provided by the mechanism that allows frequent and rapid modification of the technical solution to adapt to the ever-changing requirements dictated by the stages in the development of electrical projects.The operation of the program is based on the existence of an internal database materialized using several data tables containing various types of electrical consumers, switching and protection equipment and a series of standardized power cables from which they are automatically selected. The selection is made based on sizing and verification calculations with the help of intelligent selection methods so that only the equipment that matches the data provided by the user are selected ensuring an additional verification of the various omissions that may occur.The application is useful for designing of a new installation or for the verification of existing ones, allowing the rapid and even real-time observation of the influence of the various changes made to the project.
