The phases L1 and L3 are connected to the remaining two terminals suitable for switching. In this way, the phases are alternated if necessary until the installation work is completed or until the maximum load capacity of this five-wire supply cable is reached.
  • the connecting parts thus serve, in addition to being a supply point for the power supply to the duct / socket combination in question, and also as a stepping point for the five-wire cable to be laid to the next duct / socket combination.
  • a certain duct electrical installation group either additional duct electrical outlets are required or larger devices can be connected to the existing duct electrical outlets, it is advisable to load the capacity of each phase L 1 to L3 to think carefully in advance in order to facilitate these future installations or to allow an increase in the load without additional measures.
  • the application alternatives made possible by the links of the duct / socket combination according to the invention offer a flexible and easy way to meet these new needs. If the utilization of the various phases is properly planned in advance, the new additional duct sockets or other moderate additional loads, for example, do not require any changes to the existing power supply system. In this case, for example, the new duct electrical outlets with the links according to the invention belonging to the duct electrical outlet can be easily connected electrically to the existing duct / electrical outlet combinations without tools or separate conductor pieces. Only the shortening of the front plate of the electrical duct is associated with some work.
  • phase L1 any channel-electrical socket combination created in phase L1 would require additional channel sockets or more effective devices would be connected to the existing installation equipment, the maximum load capacity of phase L1 being exceeded, phase L3 but still would have a load reserve, the relevant, rather annoying problem can be quite a problem with an installation assembly composed of duct / socket combinations constructed according to the invention just be fixed. The total load capacity of the five-core supply cable used is then sufficient. Only the stress at the different phases is too uneven.
  • the duct-electrical socket combination according to the invention has suitable links for performing this work without unnecessary effort, because the headers of the cover can be removed easily and the front plate of the electrical duct on the connecting part can be easily opened. After the modification work, the above parts can easily be reinstalled in the electrical duct.
  • a duct-electrical socket combination which has only duct sockets according to the example as duct-electrical sockets, is of course only one of the embodiments according to the invention.
  • a duct-electrical socket combination according to the invention can be made from a separate connection part + at least one duct
  • duct electrical socket is understood to mean numerous alternative electrical accessories that can be installed in an electrical duct, such as duct sockets, various installation devices and devices without a separate protective socket, various installation devices and devices used in protective sockets, such as sockets, switches, and connecting terminals for tele , Telephone and data transmission connections and other similar electrical accessories.
  • the invention described above is a solution to installation problems with regard to the current electrical ducts.
  • the invention also offers completely new, versatile alternatives for installing duct / electrical box combinations in such a way that the end result is inexpensive and aesthetically useful in terms of manufacturing and installation costs.
