ᐅ Wallbox Preparation in Garage, New Construction

Hello

I want to have a wallbox preparation installed for our new build house, for future electric cars.

We will have a garage and a parking space in front of the garage.

I was thinking of having the wallbox preparation installed inside the garage.

What needs to be done for the preparation, and what kind of electrical cable will be needed later to easily retrofit a wallbox?

Cable from the fuse box in the garage. Elli is informed ...

Ok, is this a standard electrical cable, or does it need to be high-voltage?

That probably shouldn’t be too expensive, right?

Do it right from the start. Install a 16 A circuit in the garage for general purposes and an additional 32 A circuit for the electric vehicle. This will allow you to install a charger with up to 22 kW later on.

Ideally, also install a separate residual current device (RCD) in the distribution board.

A network cable can also be useful.

We will have a standard electrical outlet in the garage.

So for the wallbox, should we have 32A installed? That would be ideal?

If you are building new anyway, consider installing an empty conduit from the basement to the garage. This allows for any cables to be pulled through later, so you could easily expand the system even 20 years from now. For example, we connected the lighting at the garage in series with the house facade lighting and installed a sink in the garage storage room.

Regarding your question: the electrical panel should have a dedicated circuit for this. You will need a five-core cable with at least 2.5mm² (2.7 sq. ft.) cross-section. A 32 A breaker is best, as it allows charging at 22 kW. We had this exact setup pre-installed and paid an additional 100 €.
