Electricity distribution appropriately?

Hello,

Friends of ours have already built with the same general contractor as we have. They are already living in their house, ours is now being built.

The electrical wiring in their house is arranged according to the fuse box so that, for example, the bedroom light upstairs, the children's room upstairs, and the guest room downstairs are on one fuse. So multiple rooms upstairs and downstairs are on one fuse. I am a bit unsettled because someone just told me that nowadays this is no longer done this way, but each room would be put on its own fuse. Is that still current? Or an outdated approach?

The ventilation system is on the same RCD as the outdoor sockets. Since the heating is an exhaust air heat pump, it then shuts down when it detects that the ventilation is off. That means if something goes wrong outside and the RCD trips, the ventilation system and thus the entire heating also goes off. Is that proper practice?

The thing with the rooms wouldn't bother me. FI wiring: talk to him about that again. That wouldn't be my thing either. Karsten

To be able to answer the question, information is missing about whether you are rather noble, bourgeois, or etc.…

The electrical wiring in their house is set up according to the fuse box so that, for example, the bedroom light upstairs, the kids' room upstairs, and the guest room downstairs are all on one fuse. So several rooms upstairs and downstairs are on one fuse. I am a bit uncertain because someone just told me that this is no longer how it is done nowadays, but rather that each room would have its own fuse. Is that still current? Or outdated practice?

That sounds cobbled together. How many RCDs do you have in total?

I can't tell you what is right or wrong. But I can tell you how our electrician (family member far outside the line of succession) solved it.

The sockets were separated by room, the lights run separately and, because having a fuse for each lamp is probably over the top, are grouped together with several rooms, whereby adjacent rooms are not on the same fuse and RCD. This way, if the sockets trip and take an RCD with them, there is always still light in at least one neighboring room. The hallways also run separately.

Hello! I can't say what the state of the art is. However, I would generally give each room its own fuse. As already described, many people also separate lighting from sockets. Likewise, stove/oven, dishwasher, and washing machine get their own fuse or three (for the stove). Additionally, in the living room I would lay two supply lines with fuses and generally take at least two extra fuses for the sockets in the kitchen. Don't forget to provide a heavy-duty power socket for outside.

This is how I would do it. Tables are circulating on the internet showing how many circuits or fuses are installed according to the living area.

I would definitely not combine two rooms anymore nowadays. The cable is too cheap nowadays.
