ᐅ Embedding the conduit or individual wires in plaster.

Hello everyone,

I am currently working on renovating the living room.
There are two small areas that worry me a bit.
In one spot, about 30cm (12 inches) long, there is a flat cable installed, which is only minimally covered by plaster.
In another area, the empty conduit ends about 5cm (2 inches) before the distribution box. Here, five individual wires are embedded in the plaster.

Are there any serious safety risks in this situation?
What could happen if it is left as it is?

Thank you in advance.

As long as the insulation is in good condition, nothing will happen.

The use of flat cables (NYIF) is permitted in dry rooms according to DIN VDE 0100-520, section 521.7.2.3. The cable must be installed entirely within or below the plaster. It must be covered along its entire length with plaster at least 10mm (0.4 inches) thick. Flat cables must not be installed on combustible materials, such as wooden beams. Bundling of flat cables is not allowed, and fastening must be done using suitable means such as plaster patches, adhesives, or nails with insulating washers. Installation on wire meshes or expanded metal is prohibited. Installation beneath drywall panels is only permitted if the panels are fixed using plaster patches instead of screws.

This is the guidance from the electrical trade. What you make of it is up to you.
