ᐅ AFFD arc fault device / arc fault circuit interrupter issues

Unfortunately, it’s not that simple. In the event of an insurance claim, the "state of the art" is also taken into account. There is a standard that requires the use of fire protection circuit breakers. Currently, there are discussions about whether buildings with fire protection circuit breakers should receive lower insurance premiums. In that case, installing them could even pay off over several years.

No one can force you to install fire protection circuit breakers since there is currently no legal requirement.

End of 2017 after December 18
Beginning of 2018, when we were building, the standard was not part of the introduced technical building regulations and was not recognized as a rule of technology according to case law.

An objection was also filed.

I do not know if anything has changed since then or what the current status is.

Last year, however, the standard was still not recognized as a rule of technology.

I have now received the documents from the electrical sampling. Standard = without fire protection switch, but available upon request for an additional charge with fire protection switch.

It works the same way for me: I have to sign this for the electrician. At the same time, I checked with my insurance company, but of course they have never heard of it. However, they informed me in writing that I am obligated to "reduce the risk of an insured event occurring or prevent an increase in risk. If this obligation is violated, the insurer is released from its obligation."

In other words: the numbers are not relevant for now. Currently, inquiries are being made with other insurance companies.

Maybe of interest to some: Houses equipped with arc fault circuit interrupters are statistically struck by lightning more often. I don’t remember the exact study (this was explained to us by a building biologist), but it shouldn’t be hard to find.
