Connection of wallbox in the garage

Sorry, but a little more effort could … The elements are: - the wall box itself - the wiring itself - connection and commissioning

??? But he is explicitly asking _which_ costs! Answer his question instead of dissecting it.

What additional costs did you incur for this additional connection?

I am currently researching and installing as well, I could just build it like always without much planning but some information would still be good.

Everyone I’ve asked so far said at least 10mm² depending on the route because heat and charging loss would be high... but the price is quite steep for 1 meter of underground cable about 8-9€ I need 20m.

Who do I have to get my wallbox approved by? I have never heard of that.

And for wall penetration, is there recommended sealing aid like multi-ducts for single cables?

I calculate
Cable about 200 euros
Fuse box with RCD about 150
Wallbox about 400-500
Small parts and cable ducts 100 euros
Connection free because electrician in the family

Thanks

I have never heard of having to get approval for my wallbox from anyone.

From your network operator. Depending on the size, either just registration or approval is required.

An 11W cooktop (90 cm with 3 full cooking zones) is connected to the stove connection box with 5x2.5².

Up to 25m, 6² is recommended for a 22kW wallbox and that is sufficient. But, as I already said, inform yourself first. Here you have to register 11 kW, and I don't know anyone who has been approved for 22 kW because the house connection is already designed for only 27kW.

It also doesn't make any sense to take 22 kW. At home, you should charge your battery as gently as possible, so 11kW. Then an ID.4 Pro Performance is completely full in 7 hours.

If you need it faster, go to a fast charger.

And at 11kW, 5x4² can also be enough. It depends on the length. As always :D

I have a 22kW and an 11kW wallbox. The house connection has 44kW. Probably not necessary, but the idea behind it is that if friends come to visit from a bit farther away, they can quickly recharge here to be able to go home again without a stop. Otherwise, I always charge driven by [Photovoltaic surplus] with about 10kW to only charge with [Photovoltaic] power.

You won't get approval here, neighbors have tried.
