Hi
@webbah
Sorry for late response.
I gladly accept that your installation may be legal according to
Swiss electrical standards.
However, if you care to have a glance at the forum of
Tesla Fahrer und Freunde, you will find endless threads on precisely that subject - and a solution like yours is considered highly illegal, and thus (the forum being German) a dire threat to humanity .

(in fact, in the last link it seems that the particular RCD type is mandatory in Germany, but only recommended in Switzerland).
