Another thought, perhaps they are worried that 100A through a 60A RCD will not meet the tripping specification? This is unlikely although the transformer wires may get a bit hot. This might cause a bit of a meltdown somewhere but burning would be unlikely, and there is not likely to be enough temperature rise to change the magnetic properties. I wonder if this is a new kind of failure?
