I haven't seen any recent Swedish drawings, but the old ones had no 'Huischema'. Instead the circuits were drawn onto the 'Huisplan'. Just the path of the cable/conduit, nothing about the use for the circuit. You have to look at the list next to the fusebox for that.

I count 20 circuits. That is a lot in a flat, but then, this is some flat. Are there two ovens (!) or one oven and one cooktop? BTW, why are those circuits on 4mm2?

The drawings are easy to understand.

I wish I had a drawing like that for my parents house. Two 27 way consumer units. Both full. Many unmarked circuits. No drawing. I can't even find the switch to turn on the porch light. [Linked Image]
