USC710D4

Main distribution boards in medical locations are necessary whenever

  • several buildings are concerned
  • the main distribution is located in a separate building
  • a hospital, for instance, is divided into various edificial sections
  • building sections are connected to each other by use of extraordinary long line which may determine a disruption of the supply conductor

DIN VDE 0100-710:2002-11, section 710.537.6.2 and IEC 60364-7-710 defines the specification of automatic changeover devices in a main distribution board. It has particularly to be considered:

  • Changeover devices in main distributions are installed within the area of safety power supply source
  • Voltage monitoring is carried out with all active conductors
  • Switching devices are safely interlocked to each other
  • Control circuits are equipped with a “single-fault-safety” as to section 710.521.6 resp. DIN VDE 0100-557
  • In case contactors are employed as switching devices. This means the max. possible rated operational current derives as product from factor 0.45 and the operational current of the contractor (AC-3) to prevent the contacts to weld during a short circuit.
