Replace socket

Replace socket

Replacing a socket is easy for do-it-yourselfers to do. But: you have to strictly adhere to the safety regulations! And you have to know: Working on the electrical installation is actually taboo for laypeople! This is what Paragraph 13 of the “Low Voltage Connection Ordinance” says. This ban applies to all electrical systems in the house. Sockets are actually not allowed to be installed or exchanged yourself, although sockets are freely available in stores. The dealers protect themselves with appropriate warning notices.

It is essential to observe: Safety rules for electrical installation!

Electric current is extremely dangerous and can be fatal. Therefore:

  1. Before working on electrical devices, pull out the power plug.
  2. Always switch off the power before installation work. Switch off the fuse belonging to the relevant circuit.
  3. Attach the information label to the fuse box to prevent the fuse from being accidentally switched on again.
  4. Check whether the system in question is de-energized.
  5. Hands off house connections as well as sealed meters and main fuses!
  6. Only carry out electrical work for which specialist knowledge is available!
  7. Do not use, disconnect or remove the protective conductor for other functions.
  8. Check the protective conductor function after the work is finished!

After checking the socket to be replaced from the absence of voltage, nothing stands in the way of replacing a socket. After removing the cover, the socket is released from the cavity wall or flush-mounted box by loosening the fastening screws on the box or the staples. With surface-mounted versions, you simply pull out the "socket interior" and then remove the lower part of the surface-mounted socket. Then you loosen the three wires. The color coding is usually black for the live conductor, blue for the neutral conductor and green-yellow for the protective conductor.

Install the new lower part in the case of surface-mounted sockets. New holes may need to be drilled. In the case of flush-mounted sockets, the new socket insert can usually be installed without any problems. The connection is made with the color coding, as you removed the wires from the old socket. The wires are normally connected with the color coding black, blue and green-yellow. As a rule, only the connection terminal for the protective contact has an identifier with the symbol. The protective conductor (green-yellow wire) must be connected here. The connection of the live black wire and the neutral wire, blue wire, is made to the remaining terminals. The stripped ends are screwed to the socket or plugged into the corresponding clamping devices, depending on the version.

Tip: In sockets with screws, the wires should be inserted on the right under the screw. This prevents the wire from slipping out and pulls it tight because you work with the direction of rotation when tightening!

Have tools and materials ready

The do-it-yourselfer needs the following tools and materials to connect a socket:

  • Duspol (voltage tester)
  • suitable screwdriver for fastening and connecting the socket
  • Stripping knife
  • Side cutter
  • Wire stripper
  • (On-wall: drill, dowels, screws)
