    it seems they are intended only to protect the fixed wiring part of an installation.

    I'm not sure about that - there's plenty that can go wrong in flexes, extension leads and the general "mains" side of appliances - which in theory an AFDD should be able to detect

    (although I'm increasingly suspecting that the current crop might not in practice).
