ᐅ Precast Concrete Slab Electrical Installation

Hello!
Since we haven’t fully decided on the lighting yet, I wanted to ask if it’s possible to install the conduit not directly in the ceiling, but instead to drill a hole from the attic afterwards and then lay the conduit.
The piping will then be covered with 30cm (12 inches) of cellulose insulation.
Could this cause any issues, or is it absolutely necessary to embed everything in concrete?

Thank you very much.

Hello,

you don’t have to embed it in concrete. This is usually done only to prevent the cables from interfering with or being damaged by the floor structure above. You can do it like this.

Best regards
