Hello everyone,
We are currently discussing whether to install lightning protection in the main electrical panel according to VDE regulations DIN VDE 0100-443 (effective from 01.10.16). Since our planning was approved before 01.10.16 and the shell construction is already completed, we have the option to decide.
If it makes sense and prevents damage, I am happy to install it and invest the few hundred euros. If it is just a formality or requirement without significant benefit, I would prefer to avoid the expense.
Are there any opinions on this?
Thanks in advance!
Best regards!

I believe this question is a bit too specialized for this forum to provide a fully competent answer. However, I’m happy to share my opinion.
I think it depends. Basically, the standard is heading in the right direction. In short, it requires surge protection type 2 to be installed in single-family homes. Beyond that, the entire surge protection concept up to type 3 should be well thought out and properly executed. Simply installing a type 2 surge protector blindly is not effective.

Additionally, a small note: the foundation earth electrode standard DIN 18014:2007-09 came into effect about seven years ago, yet it is still frequently violated in new constructions. This serious disregard is mainly due to the lack of knowledge among architects, structural builders, and even electricians. Meanwhile, this standard has been replaced by the newer DIN 18014:2014-03. I believe that even in ten years, a large number of houses will be built without compliance to the standard...

A foundation earth electrode is always installed, but in about 95% of new buildings it does not meet the standard.
As mentioned, this is generally not a problem, but I would recommend additionally protecting important appliances (e.g., heat pump, heating system, etc.) with Type 3 (fine protection).
