Yes, you're right. I am sure there;s a limit to

leackage current. It's not zero, but ti's probably not that high either.
Mins filters often have cpaciaotrs from the power-carrying wires to
ground, and they will pass some AC current.
The RCDs on the supplies into our data centre are settable; they can be
set at least as low as 30mA but normally they're set to over an amp and
can be set as high as 6.3A residual current. What's allowed depends on
the context (and that includes the time they take as well as the current).
