Jordforbindelse og nye stikkontakter

Recently, I bought a a house at Birke Allé 13, Brønby Strand. The house was built in 1965 with renovations in 1990 and 2020, and has a modernized fusebox. According to Elrapport couple of the power sockets on the ground floor have ground not wired up even though the socket has the ground pin. Additionally, none of the sockets upstairs except for in the bathroom have sockets with ground - and the couple sockets we checked had no ground wire at all, only line and neutral. The task would be to wire up ground to all of the 3-pin sockets that are missing it, and add a couple grounded sockets upstairs in the office room. Additionally, if it makes sense, we would like a dedicated fuse for the upstairs office room as it only has 13A and will have multiple high-power devices - but only if it doesn't require a lot of work.
