I won't continue but let me mention one thing. My day job is in industrial automation and deal with some serious power including one 1000 Hp motor running of 6 Kv, another 2000 Hp motor running of a 6 Kv variable frequency drive weighing 7,5 tons (the drive not the motor) and several other 200 Hp plus motors on regular 400 V, not to mention the rest of the smaller ones. Solar panels alone, we have more than 3 Mw (3000 kw) installed so, that's a lot of energy to keep under control and many RCD's, so, I really need to know something about the field ;)

Yep, you clearly know your onions HTF and like I said it was your choice of terminology and phrasing that lead to my post. As you know terminology can be crucial 😉.
It makes me smile when people use the terms : Ground, Earth, Negative and Neutral when the vast majority of times it really should be 0v.
Most of the time we all understand each other but when you have to explain the subtleties of a 12V DC inverter supplying 230v AC in a vehicle which also has a ' Chassis' to further complicate things, then discussing what to do about "Earthing" the terminology used is a potential minefield. I've tried to explain to quite a few about what's what but when I start by saying. "OK, the first thing to understand is that the supply from a transformer has a floating AC supply and doesn't yet have a live or neutral" they've already glazed over and lost interest 🤣🤣
