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

As promised, I took a few more photos—hopefully, they help...

Did you always have to replace the same fuse or different ones?

3x 16A (3x 16 amps) is certainly not too much for an entire house.

3x 16A with heat pump and then such a distribution?!
Wow.
Let a qualified electrician, a master electrician with expertise, take a look.
In my opinion, this should be fundamentally inspected and renewed.

3x16A is insufficient for a typical house. When the heat pump is running along with other appliances, for example in the kitchen, a 16A fuse trips very quickly. Since these three fuses are your main fuses, the electrician should check the capacity of the supply line again. Usually, from the main connection to the meter box, a 10mm² or 16mm² cable is installed. These can be protected with 50A or 63A fuses. Since the main connection may have a 63A fuse, a 50A fuse should be installed in the meter box for selectivity.

This is what it looks like now; all I see are more loose cables and connectors.

The heat pump is definitely of interest to your energy provider. At least, we had to report it. We also installed wiring to allow for an electric car. With a heat pump, everything needs to be properly distributed. If you have three circuits, the loops and consumers should be reasonably balanced!
