Is the house connection capacity of 14.5 kW sufficient?

That will surely be the sls in the fuse box. It comes in different sizes.

The supplier usually secures the actual house connection with 63A. That is then 400V*63A*root 2, so about 35kW.

Then comes the sls in the fuse box, which, as mentioned, is available in different sizes. Presumably, a 25A will be installed for you, which corresponds to 14kW.

I just looked at ours. We have a 35A, thus about 20kW.

What happens if you exceed the 14kW is quite simple. The contactor in the sls will trip.

You should try to talk to the gu to get more.

We also have an 11 kW induction hob, heat pump, tumble dryer... I think 12 kW was once the absolute extreme, but then everything really has to come together.

I also think that we are talking about rare events here. You would have to wear everything in winter and have the cooktop on booster mode together with the oven at 250° with grill top and bottom, hot water tank used up, and both showers running. Then also microwave and vacuum cleaner. If the hairdryer (sorry, hot air hair dryer) turns on... you can probably reach 15 kW. But I would just like a little more buffer...

And the "larger" SLS is enough then? It doesn’t have to be a "thicker" main line laid to the house?

Warning dangerous half-knowledge.

I seem to remember that back then the network operator's conditions stated a maximum of 100kW. Anything above that would have cost more.

The cable that is brought into your house is already quite thick.

And you have absolutely no influence on the network operator's connection. That is a matter between the network operator and you.

So I think 100 kW would be more than enough for me. Basically, the aforementioned 35 kW should be sufficient as well. I'm just uneasy if at 14.5 kW it would already be game over...

So I took two pictures.

The "cable thickness" comes from the network operator



And it goes to the fuse box.


So there is still some room to grow.

The problem is that you don't know what is coming. Topic: electromobility.
