Fair enough - that sounds like reasonable use of what seems like an imperfect form!I didn't used to do EICRs but on installation certificates I used to put the RCD(s) on a separate line above the circuits they covered and fill out accordingly - BS 61008, conductor sizes etc. and of course the test results.
I would imagine that you would probably agree that it's pretty clear from the Schedule (and the electrician's comment that "some" of the circuits are not RCD protected) that the three circuits 'above' (in the Schedule) "RCD" are not RCD protected, whilst the three circuits 'below' "RCD" (in the Schedule) are RCD protected (hence only those three have an IN recorded)?
However, as I said, although there is a column for recording "RCD operation time" for each of the three RCD-protected circuits, the results are recorded as "N/A", which suggests that RCD tests may not have been done (event though the test device serial number is given for RCD tests).
