Hello dear forum,
We are currently building a new house with Keitel-Haus. In the additional cost invoice for the selections, we were informed that we need to install residual current circuit breakers with arc fault detection because our house will be built after December 18, 2017. After doing some research, I found out that this is due to a new VDE standard, which requires these devices to be installed, among other places, in wood-based constructions.
According to the insurance company, these are not necessary unless explicitly required by the local authorities. For the insurance, only what is specified in the regional building code regarding fire protection counts. The switches would cost almost 3,000€ for 11 circuits, which we would prefer to avoid...
Could you please clarify how necessary these are and whether they are really mandatory?
Best regards

Could you send me a picture of your distribution board? I’ll see if I can take one this evening where you can actually see something. Unfortunately, I don’t have proper lighting there yet.

In my case, the house manufacturer covered the additional costs after I was able to show that the standard is just a standard and not a law... However, they couldn’t find an electrician who would still install it without it.The DIN VDE is legally established. Take a look at the laws.
- Low Voltage Connection Ordinance § 13
- Energy Industry Act § 49

Could you send me a picture of your distribution panel?I almost forgot again, here are two pictures showing the inside of the distribution cabinet. The circuit breakers next to the residual current circuit breakers are simply divided among the different rooms/devices.

So, it’s not one switch per circuit, right? No, at least not in my case.
