Renovation of the electrical system - without opening the wooden ceiling

Hello everyone,

we are planning a renovation of the electrical system and are wondering how to proceed in the areas of the room ceilings. There are partially high-quality suspended wooden ceilings that I would prefer not to tear down because of laying a cable.

Is it possible to connect the old wiring to the new electrical system until a future ceiling renovation?
Which regulations need to be observed and how should one proceed?

What does the electrician say? Without knowing what is installed there, probably no one will be able to help you properly.

Hello Siggi,

Lord je....what's going on there, why (instead of Neige) do I suddenly come up with this nickname? *shrugs*

Already on the to-do list.

Rhenish greetings

Unfortunately, I do not yet have access to the property, but I estimate that about 3 possibilities are likely: 1. three-core cable 2. two-core cable 3. [Stegleitung]

My personal research showed: 1. technically no problem 2. only with lamps that do not require a protective conductor 3. not permitted

To specify the question a bit, under what conditions can the old cables remain?
