Then any derating factors required

There would be no de-rating of the mcb but the cable selection would be subject to an number of derating factors such as running through thermal insulation, ambient temperature etc. It may be that to load the mcb to near capacity your circuit conductors will need to be in excess of 1.5mm.

Yes very true, I'll hold my hands, now re reading my post I was meaning cable, not that he asked this. Oh well
