Русский: Процесс установки УЗО в этажном щите.
  • В современной установке построена TN-C система, несмотря на то, что в те времена уже требовалась TN-C-S от новых построек. На сегодняшний день TN-C вызывает проблемы с использованием УЗО, поскольку при обрыве PEN-проводника, УЗО будет пропускать опасное напряжение на металлические корпуса.
