Hello,
During our renovation, the house electrical system will be updated. The electrician who will carry out the work offered that I could do the chase cutting myself to save some costs. He would mark everything, set up the machine, and provide a brief instruction.
Most of the walls are 11.5 cm (4.5 inches) thick. Vertical chasing is not allowed there. Currently, there are also cable ducts installed. Is it still permitted to use these nowadays?
Horizontally, conduits with two conductors are installed. It would be possible to simply chase over them and install the new cables flush-mounted (such as NYM cables and network cables).
What alternatives are there for vertical chases, and what is allowed?
Best regards,
Jan

Today I chipped away the plaster. It is about 1.5 cm (0.6 inches) thick. I asked around, and the opinions are mostly along the lines of: it’s been like that for ages, nothing will happen / be careful if you chase on both sides / my brother-in-law did the same / it will be plastered over again anyway...
I will wait and see what the electrician says. Unfortunately, he is on vacation until Tuesday.

The old conduit pipes already embedded in the masonry are unfortunately too narrow for NYM and network cables. Can you remove the conduit pipes? If so, you will likely have a fairly large channel open. Regarding NYM and network cables, minimum spacing requirements must be observed.
