Cooker connection not via RCD/FI although available - is rewiring advisable?

Ah, many thanks!

But that also means I can at least prepare everything behind the kitchen with the Merten connection box using the Wagos (oven directly, L2 socket, L3 socket) and the electrician then replaces the RCD at the front, right?

Thanks to the 9cm wall distance, I would have used slim surface-mounted boxes and clamped them into the oven connection box with a sheathed cable.

Are there any objections to this?
