No RCD/RCBOÂ* has a 'functional earth fly lead'.

The white lead here ...

earth something in the switch...





It allows the RCBO to continue working and detect a LE fault in the
unlikely event of a missing/lost neutral.

You haven't looked at the circuit diagram have you?
Or thought about what you just said.

How is the current - the massive current - that should flow down the
neutral going to get back to base if there is no neutral?

Down that poxy little wire to *earth*? What????
Earth is simply safety, it never passes significant current except under
fault conditions. You cant operate *at all* without a neutral.
