There is no actual requirement for a RCBO to have a FE connection

I couldn't see any mention of PE or FE in BS EN 61009-1, other than in
deleted wording.

The 2004 version has a requirement to use label the terminal with the
protective earth icon as per IEC 60417-5019a rather than the functional
earth symbol as previously recommended!

Can't recall where I did see mention of it now.


Do RCBO's still consume power even when no user devices are
using power ?.
Assuming 6 in the consumer unit of a typical average house,
how much leccy is used per year ?.
