If it's relatively modern cable it might well have the size embossed periodically on the outer sheath - but you may well not be lucky enough to be able to see the appropriate part of the sheath! Failing that I'm afraid that it's the calipers or micrometer!
Which is why it makes no difference regarding the fault current compliance.
Hmmm. The fault current loop (hence the PFC) includes the L conductor, which, for the bit of cable in question, is 1.0mm² in one case and 1.5mm² in the other.
Very true. However, whether the CPC can handle it is determined by a calculation which depends on PFC, which, in turn, partially depends upon the CSA of the line conductor. This calculation will therefore be different for 1.0/1.0mm² and 1.5/1.0mm² cables.
Yes, I know it's all pretty silly because of the very short length of cable concerned, and that's one of the several reasons why I know what I would do (and not bother to do!) if we were talking about my own home. However, as I said before, the OP has been advised that it would, strictly speaking, be necessary to confirm that fault protection was adequate for the arrangement to be compliant - and it's not for me to suggest to him that such is not strictly true (because it is!).
