Electrical installation - is everything okay with it?

Hello everyone,

this is my first post here in the forum, I have mostly read as a guest in the past and informed myself about some things. But now I am hoping for feedback because I am really unsure.

At the end of February, we moved into our new end-terrace house near Singen (Htw) and are largely satisfied. However, the electrical installation worries me:

In our electrical box, we have three fuses, of which I had to replace one from time to time (there were two 10 A fuses which were replaced by 16 A, and one 16 A fuse). This weekend, for the first time, a 16 A fuse "blew," so nothing worked at all... unfortunately, I don’t know when that happened, as we only noticed it in the morning while showering because there was no hot water since the heat pump also had no power.

I then looked into the distribution box and opened the cover behind the fuses. You can see the result in the attachment.

What do you think? Does it often look like this or is this already botched work? Unfortunately, I don’t know anything about electricity and the local electrician just says that all the measurements are good, everything else is optics… is he right?

Thanks in advance for your feedback, I hope you can help me a little.

Best regards, SimKN

Is this a new building?

Wow, catastrophic is something else, but in a new building I would not have expected this "look."

Unfortunately, I am not an expert and do not believe that your problems depend on the look, but if the same quality of the look is transferred to the rest.... I don’t know.

Well, beautiful is something else. Wago terminals really have no place in the distribution box.

I don't see any fuses that you are talking about.

I did not take pictures of the fuses, I will make up for that tonight... They are located in the top left in a separate "field".

I would have the measurement protocols handed over to me, in case you don't already have them. Then have the measurements checked.

Measurement protocols are quickly filled out. It even works without a measuring device..

I'm not an expert, but you could also post the photo in the Facebook group „Pfusch am Bau“.

Just coming up with the idea to install a 10A fuse is already totally stupid.

Looks like an apprentice.
