Especially when the time comes and all your neighbors are driving an electric car, the suppliers have other problems at first

Without knowing what one might possibly, under certain circumstances, most likely need later, as suggested by Gartenfreund, have a sufficiently sized empty conduit installed from the meter cabinet to the garage while maintaining large radii. For example, a corrugated conduit M40. Standard M20 is not sufficient for a proper cable (see attachment).

You won’t get more than 5x4 mm2 through a conduit anyway, and your house connection doesn’t allow for more. Therefore, I wouldn’t install a conduit, but rather 5x4 mm2 and that’s it, if you want to be on the safe side.

Do you know each other? If he has a good breakfast ...


Are you neighbors?


Are you sure that with 15m and installation in a conduit, as well as a desire for 32A in the garage, the cross-section you suggested is sufficient?

Caution. 4mm is not sufficient for 32A in a conduit with 3 loaded conductors (installation method b2). 4mm would only be possible in surface mounting under ideal conditions.

It may be necessary to take reductions into account if the cable runs together with or alongside others.

Sure, everyone has different skills when it comes to cable laying, but larger than 4x5 mm2 through an empty conduit over 15 meters I consider very difficult. For me, 5x4 mm2 would be the largest reasonable cross-section and I would NOT put it in a pipe, as mentioned. Voltage drop should not be a problem at 15m and 32A, even though I have not calculated it now. If necessary, one has to be satisfied with 24A.
