OK, it seems (from what I can find online) that advice at the moment is to code C3 if a plastic CU is under wooden stairs or in an escape route - but not to even note it otherwise. So if the plastic CU is somewhere out of the way - not in an escape route or under stairs - what do you put for checklist item 4.4 "Condition of enclosure(s) in terms of fire rating etc (421.1.201; 526.5)" ? (Model EICR form in appendix 6)
It's not C1 or C2, consensus seems to be that it's not C3, it's not FI or N/V or LIM or N/A.
Can't just leave it blank. And if consensus is that it doesn't even need to be noted, then putting a C3 here would then lead to the question of why there isn't a corresponding entry in section K.
