For simple easy remembering...
Make ur own excel sheet as per below
(its strictly not a technical way)
for Eg:for breakers 10-100 dive the breaker value with 4.5 you will get some value go to thte next cable size
10A
10/4.5 =2.2sq.mm
go to 2.5 sq.mm
--------------------------
you can use this formula till you are familiar with the cable sizes (Y)
