Description
English: Utility cabinet with two introduction sections and one junction.
  • Junction section is required here cause of using shared power cable between transformer substation and building.
Русский: Вводно-распределительное устройство с двумя секциями: для коммерческого здания и жилого дома.
  • Шкаф посередине используется для соединения магистрального кабеля с ответвлениями на потребители (для питания зданий на данной улице используется магистральный кабель, поэтому из-за невозможности питать каждое здание отдельным кабелем с подстанции, ВРУ установлен вблизи здания в месте ответвления магистрального кабеля потребителям), предохранители стоят вначале линии (защищая силовые кабели на всей протяжённости, а не пару последних сантиметров в главном щите) и благодаря расположению общего счётчика электроэнергии за территорией потребителя кражи электроэнергии и несанкционированные подключения полностью исключены.
  • В России и прочих странах бывшего СССР можно довольно часто встретить ошибочное совмещение вводно-распределительного устройства с главным электрощитом здания даже в новых установках, что является как технической безграмотностью проектировщиков так и человеческой глупостью составителей ПУЭ.
