I think we're at cross purposes here, probably my fault I failed to make myself clear -- I totally agree with you and your comment is virtually identical to my comment to the client asking why they had pre-translated "courants faibles" as ELV. And it does cover non-power wiring. Long & short of it, though, is that I'm pretty sure what 0.8 means :)

Ah no, I think here it is you who are a bit adrift! 'courants faibles' does NOT means ELV — in the sense of very low voltage power for special uses.
'courants faibles' very specifically means NON-POWER wiring — in most cases, I translate this as 'signals', since it may include AV, telecoms, and of course now computer networks etc.
Hence why 0.8 mm² makes perfect sense, as I originally suspected, as these sort of sizes are very common for signals wiring, including sometimes the rigid-core cables often used for telecoms / data — e.g. UTP as I mentioned.

These are confusingly always referred to as 'courants faibles', even though as you say, 'voltage' would be more appropriate — and is of course often used when referring to the things that are carried on this wiring. Remember that in FR 'courant' is often used (in a rather colloquial way!) where we would say 'power' — e.g. 'coupure de courant' = 'power cut'; remember too that when they really want to say 'current', they often use 'intensité', little used in EN.
So I'd caution being extemely careful about over-interpreting by assuming that this has anything to do with ELV power uses.

You suspect right. The French title of the doc is "Courants faibles" but the client has pre-translated it as "Extra Low Voltage" and seems to use "courant" and "tension" interchangeably throughout the 2 docs comprising the tender. I did point out the problem of confusing the two in the first doc last week, but got no reply so seems to be a typical case of 'I know what I want, just get on with it' which is less than satisfying to say the least. - In the meantime, however, I think I've got enough info from you guys now to be able to proceed - with grateful thanks as always :).

I'd be surprised if it was headed "Lot électricité basse tension" if that would include ELV, unless this is some specific subset of it.
That said, assuming you potentially have 'courants forts' and 'courants faibles' (the usual breakdown), it's true it would be difficult to see quite where else to fit it in...

Although it doesn't specifically say so, all the devices etc seem to imply an Extra Low Voltage system.

J’y pensais que le tableau aurait pu être fourni par une succursale étrangère.

The French heading is "Section minimale"

as French electricians normally use metric units. But why is the table called "Minimum cross-section"? Or is this your translation?

The text refers to what country?

BTW: 0.8 is not strange for household appliances. Its nominal cross section is 0.75 mm² in most European countries used for ampacities up to 10 A.
