    Suitable MCB for Radial Circuit?

    Hi all, I am installing a Radial A2 circuit which by rule it should have an MCB of 32Amps, but when I reference the table 4D1A using reference method A or B, current are 26 and 32A respectivitly.. So the question is why we go for a 32A mcb and not 25A one? Thanks
