Those are all good points, Mike.
So it seems that we can now look forward to an RCD at every isolated outlet. Sounds good to me; it would also help in identifying them, which would be another "plus".
Do you have any idea how the 5.6 mA value comes about?
On the last point, I suspect that any faulty equipment would just have been removed, then repaired and returned to service without any further investigation being carried out (or recorded). Also, is it normal practice for theatre staff to keep a log of LIM alarms (and the action taken to silence)? Somehow, I doubt it.
