ᐅ Relocating an Electrical Outlet / Installing a Flush-Mounted Outlet / Baseboard

Hello everyone,

I want to install a new socket 4 meters (13 feet) away from an existing flush-mounted double socket. The textured wallpaper must definitely be preserved, so routing the cable inside the wall is not an option. Since I plan to install new laminate flooring anyway, I am considering hiding the cable (NYM 3x1.5 mm) behind the baseboard (see sketches). The section from the baseboard to the respective socket I want to do with a simple square cable duct. I have the following questions:

• Regarding the existing socket (flush-mounted):
What is the best way to branch out to the outside?

Is it allowed to make a hole in the edge of the plastic cover? I would then cut the cable duct flush to the rounded edge of the socket housing.

Or do I need to drill diagonally from the outside a few centimeters away from the socket and lead the cable in that way? (Of course, not on the side where the existing flush-mounted cable is already running.)

Are there any other alternatives?


• Can the new socket also be a flush-mounted box, even though the branch is surface-mounted? In principle, I would then need the same as before, a neat transition (surface-mounted <-> flush-mounted), which brings me back to question 1.

I would appreciate any advice. Looking forward to any tips!
Thank you very much in advance.

Usually, for both boxes (inlet and outlet), a small groove is made in the masonry to route the cable sideways next to the cover. This can generally be done quite easily with a screwdriver without needing a hammer. You can cut into the box with a utility knife. (Sometimes there are already breakouts that you just need to remove.) Alternatively, a standard extension can be used. In that case, the cable will come out a bit further away from the box. It just doesn’t look as "neat." Good luck...

Try searching on Google for "plug-in adapter."

This is how I set it up in our rental apartment. The cables are neatly laid in a small conduit. Often, you can also try accessing it from the room on the other side of the wall. In our case, I ran the cables from a corner in the living room through the wall into the bedroom, which gave me power in the corner for the TV and hi-fi system.
