Input and metering boxes are installed in schools, kindergartens, single-family houses and garage cooperatives. In such buildings, they do not require additional equipment and can independently control all the electrical circuits of the building. They are also used in factories, pharmaceutical companies, shopping malls, agricultural enterprises: poultry farms, vegetable and livestock breeding farms. In such organizations, the box is mounted together with other switchboard equipment. For large facilities, several boards may be required, it all depends on the complexity of the electrical circuit and the area of the building.
The boxes are assembled with various degrees of dust and moisture protection. Depending on the customer's wishes, it can be IP21 or IP54. The modules must be equipped with an input automaton (switch), current transformers, a power meter and protection systems for the outgoing line. Fusible inserts are also mounted inside to protect the equipment from overloads and short circuits. If necessary, they can be replaced with other protective elements. Each box must have several grounding buses. To exclude direct access to the parts under voltage, the front of the cabinet is closed with a special panel.
