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

Hello, I have the same issue. The prefab house supplier claims that the electricians working with them will no longer approve any circuit without an AFDD, because if they don’t work according to the "state of the art," they could be held liable in case of an emergency. Also, their partner Siemens wants to make money < my assumption
Does anyone know an electrician who feels confident installing the electrical system of a single-family house safely without AFDD in all 25 circuits, and who may already cooperate with prefab house suppliers, preferably Danwood?
