Is 0.75mm Flex in conduit behind tiles and tile backer sufficient for led lights (6w) or Fan (4w)?

There's a duplicate thread in DIY with the same subject, but neither has the full information.

Interesting. The way I read table 52.3, from left to right, 0.75mm2 flex is permitted.

Do you mean the bottom section for single appliances and other applications?

It is my understanding that this really relates to the final aspects, such as pendant drops etc rather than fixed wiring

I do indeed mean the bottom section, but I have selected 'flex' from column 1 first, then 'any other application' from col 2 (I assume this means 'any application other than those others listed for flex'), which gives me 0.75mm2 from col 3.

It seems logical to me to work from the table in this order, rather than working from the middle outward (though the table really could be clearer on this).

I had also assumed that the minimum 1mm2 was for non-flexible cables due to smaller conductors being prone to damage, either during installation or in use, whereas this wouldn't be a problem for flexible cables.
