@Julie.
My thinking, the capacity of which is limited, is that potential for issue exists due to the way in which this protective device operates and the fact that one new appliance has the potential to change that operation.
I take the above points, but believe old wiring colours aren't a good comparison as they will have no impact on a householder who doesn't tinker with fixed wiring in their home. Replacement of an old or failed appliance doesn't generally require consultation. Given that a significant number of domestic EICRs are carried out for the sole reason of complying with rental legislation, I feel this adds another layer to the issue as no one can look around the property and assume risk on the basis of appliances present at time of inspection.
Similarly, the issue of premature collapse doesn't generally involve variables - risk exists or it does not and remedial work is quite simple.
Furthermore, most inspectors who carry out EICRs won't have any means of detecting DC leakage, much less any interest in attempting to do so.
What I have taken away from this discussion is that a number of opinions in favour of not coding type AC RCDs are based on customer reaction. While I understand that position, I don't consider customer sensibilities to be a factor of testing and inspecting. It's an interesting discussion about what, on the surface, appears to be a simple issue.
