All they have to do is draw the current for the electronics *before* the
imbalance detector.

WHAT electronics?

THESE electronics ... the white earth flylead seems to connect to a pin
on the balance transformer (whatever the correct term might be)

Blimey. I'll concede that. They have devloped since my time...BUT if
you look at the circuit diagram later in that video, you will see than
no earth is involved. The only possible thing it *might* do is nothing
to do with RCD detection per se, but it MIGHT detect voltage on the
neutral with respect to earth.

Not something that bothers me at all.
