Fault arc circuit breaker in prefab house

It's all fine as long as you have it in writing as part of the policy.

Hello, I have the same problem. The prefabricated house provider claims that the electricians working with them will no longer approve any circuit without the AFDD, because if they do not work according to the "state of the art," they could be liable in the event of a serious incident. Furthermore, their partner Siemens wants to make money < my assumption

Does anyone know an electrician who dares to design single-family house wiring safely against fire without AFDD in all 25 circuits and who possibly already cooperates with prefabricated house providers, preferably Danwood?
