  • Familiarize yourself with the DIN 18015 standard T.3. Find the standardized connection zones in which the cables correctly (flush) should be postponed.

  2. With a wall cutter, a hammer drill or hammer and chisel Now break the cable slot. The empty pipe or conduit should, if he is in the slot, with the Rohmauer are flush or recessed (without plaster).
  3. Insert the vermantelten power cables or conduits in the slots and fix it at regular intervals with plaster.
  4. Let at the ends of the cable enough rest through the later clamping.
  5. Now you can plaster the wall slots again.

Publishing a power cable to the wall

Especially when laying a power cable for an additional lamp or TV in a finished apartment, it is advisable to lay the cables over the plaster.

  • You can run the cable to either a cable channel or cable clamps. These are available in different materials and designs, so you can paste it harmoniously in your home screen.
  • When mounting a cable duct in the edges of the walls (either on the floor or ceiling), it remains relatively unobtrusive.
  • The cable duct is fastened to the wall in the normal case with screws and dowels.
  • If required, the cable channel can also be covered.

If you lost the power cord properly, your electrical consumers just have to connect and check and test the installation.
