The strips should not be connected in series, I wouldn`t worry about the antenna, as something would blow the differential like a fuse.

That`s why at the beginning I didn`t think about securing N at all, especially since you have a PEN distribution for PE and N somewhere close to your house, but if you secure it, there is no threat.

How "close" to the house is it to secure it. Unless the PEN section is in the same switchboard as the limiter. A few meters of cable from the distributor is of great importance.

I disconnected the computer from the power strip and the problem disappeared.

Let`s assume that the limiter is damaged and begins to conduct electricity, should I use any additional protection?

If the limiter short-circuits, the closest protection, in this case probably the pre-meter protection, will go out.

And why do you have overvoltage protection for a three-phase installation????

If you read the whole topic, you would know that he had one lying around his house, so he used it, what difference does it make?

If it short-circuits, the varistor will turn into a piece of cake, the pre-meter will probably not fail, and if it fails, you have S and you can turn it on.

Don`t think about anything anymore.

Topic summary

The discussion revolves around a user's electrical installation issues, specifically frequent breaker trips and fuse blowouts when using high-power devices like an iron. The user has a 25A 30mA differential switch and 5 circuit breakers, with a 16A socket fuse and a 20A meter fuse. Problems arise when testing the differential or using the iron, leading to simultaneous fuse blowouts. Various responses suggest checking the type of fuses (B vs. C), potential overload from inductive loads, and the need for proper surge protection. The user is advised to disconnect devices, test circuits individually, and consider the condition of the meter fuse. The conversation also touches on the installation of surge protectors and the importance of proper wiring and fuse selection to prevent electrical hazards.
