ᐅ Electrical Installation – Is Everything in Order?

Hello everyone,

This is my first post in the forum. I have mostly been reading as a guest in the past to gather information on various topics. Now, I’m hoping to get some feedback because I’m really unsure.

We moved into our new end-of-terrace house near Singen (Htw) at the end of February and are mostly satisfied. However, I’m concerned about the electrical installation:

In our electrical panel, we have three fuses, and I have had to replace one of them several times (two were 10 A fuses, which were replaced by 16 A fuses, and one was a 16 A fuse). This past weekend, for the first time, a 16 A fuse blew, so nothing worked anymore. Unfortunately, I don’t know when it happened because we only noticed it in the morning while showering—no hot water, since the heat pump had no power.

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

What do you think? Is this common or is it poor workmanship? I have no knowledge of electrical work, and the local electrician only said the measurements are all good and that everything else is just cosmetic... is he right?

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

Best regards,
SimKN

So, I have now looked at the pictures again on my PC in a larger format, instead of on my smartphone. It doesn’t get any clearer, but I remain a layperson.

Nevertheless, I took the trouble to dismantle my electrical meter cabinet, just for you. It might not be a 100% reference, but this is how it could look. The difference is noticeable, and our cabinet is smaller yet more fully equipped.

@toxicmolotow: This already looks much better, but there are still a few points to address. Terminal blocks must be mounted on insulated DIN rails. Additionally, grounded rails need to be clearly marked as such. The labeling of the terminal blocks is also missing. This might seem a bit picky, but if you’re reviewing the setup, you should point out what stands out immediately. Another thing to note is that the assembly carrier on the far right is installed upside down.

Phew, I think I’ll keep my cabinet closed after all^^

Okay, but I don’t even know which components you’re talking about.

I’ll ask my electrician (my father-in-law) about it *laughs*. I’m sure I’ll become quite popular *hehe*.

Until yesterday, I thought the thing was good.

@toxicmolotow, thank you for your effort!
This is basically how I expected it to look, at least visually.
With my cupboard, I’m already worried about getting too close to it...
I hope that on Friday I will receive a good proposal from the developer.
