Due to the representational architecture of an electrical installation arrangement 8, a good overview of the processes within the relevant installation, but above all also of the status of the installation and the individual branches, can be achieved at a central or decentralized location. Due to the good overview of the electrical installation assembly 8 can be compensated by selectively switching off individual protection devices on the
