The small ones often do not have the functional earth fly lead.

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.

RCD's do not have these fly leads.

And ******s oversleeve the flyleads with green/yellow. But then some
RCBO manufactures have a flylead with a green/yellow cable.

Probably worth highlighting the reason for Adam's indignation regarding
over sleeving. While the correct colour sleeving for a protective
conductor is the normal green/yellow, the correct colour for a
functional earth is actually cream.

Is this "functional earth" in the sense of reducing interference (like
AV interference)?
