Hi,

I was speaking to a electrician yesterday about exactly the same problem. On this circuit the RCD would trip if nothing at all was connected. He advised to use a 500v test between Neutral to Ground. In the majority of cases this will show the breakdown. I've had quite a few combi-microwaves that have had insulation breakdown of the heater element also.

Regards. SJM.
