Is the house connection capacity of 14.5 kW sufficient?

The architect has already listed all the items in the application. That is sufficient, right?

The connection capacity provided by the supplier is usually calculated by the electrician in the meter application. Without corresponding consumers, lower values result. 15kW should be sufficient without any problems. However, if the general contractor wants to save on the electrical installation, it’s a completely different matter...

So, had an appointment with the electrician on site today. He advised us (me and the builder of the rear half). The 14.5 kW is apparently a purely calculated average value that is just written in to have something written. The standard in Berlin is 50-63 A and about 40 kW. No idea if that makes sense, I slept through the 7th grade (when electrical engineering was covered) and gave up physics after the 11th grade. In any case, he said I can be calm, I can connect whatever I want to the standard house connection, as long as I don't have commercial applications, it basically handles everything.

Hi,

I can only say that in NRW (Westnetz) above a "free limit" of 30KW and up to 30m trench length every KW costs 20.62€ (net) extra. In connection with charging stations (only then there is basically the normal connection like construction power for free), we therefore only pay 424.77 € net.

This offer is apparently only valid until 31.12.2020. And per residential unit, a connection value of 10.8KW is "specified" by Westnetz.

Wow, I already have 11 kW at the parking space of my future apartment. 22 kW for charging cars is almost overkill.

Since I have to order the network connections this weekend, a quick question to the group: 30kW is also sufficient when planning electromobility in 2020, right?

Even with a 22kW wallbox, it can only draw the full 22kW for a very short time before the charging management reduces it.

The cable is supposed to be 35mm²; after a quick look at the tables, significantly more amperes should pass through it than the household fuse with 63 amperes. If I later need more than 30kW, only the household fuse would be replaced, right, or did I misunderstand that?
