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!

    I think you are being fooled from that web effect where the same images and captions are re--used in the description pages of many different products - it will be flexible, and it will achieve that flexibility by having the right number of fine strands.

    The clue is in the bending radius of 15 diameters for repeated flexing - this sort off stuff finds itself supplying portable tools and in machinery that moves repeatedly back and forth and the cables coil and uncoil every day for hundreds of cycles.

    Eventually in those applications the cores work-harden and snap, but if strain relief has been designed right that is many years down the line.
