ok - Just ran the calculator on TLC website (for what its worth) and it also came back as 10mm at 50 degrees, pulling 8kw over 14m is sufficient. I guess I'm being over cautions! like you have said @EFLImpudence normally that would be a 20a or 32A breaker for the whole floor + 6A lighting and be done!
Just concerned about it running in insulation in the future, and if i get round to solar not having to re-run cables!
