Radial Voltage Drop Calculation?... By Load or MCB Rating?

Nano Brewery
I'm doing the calculation for total voltage drop.  I have 14 radials/ways going out.  As I understand it, that would equal a max allowance of 0.285% voltage drop per radial/way.  Or some sort of mixture throughout not exceeding the 4% drop allowance overall.  Firstly, is this correct? 


Secondly, should I be doing my calculations based on actual Load or the MCB ratings of the individual radials/ways? 


Thanks in advance!

    The H07RN-F I'm looking at has rigid conductors:

    It shouldn't have - the -F bit of the designation specifically means a fine stranded conductor.


    H= Harmonized

    07 = 700-ish volt rating (specifically 450/750V)

    R = rubber insulated

    N = Chloroprene rubber sheathed

    F = fine stranded
