The MDB Maximum load depends on the Transformer,it is not
constant for the max load,if you want make load calculation
first you consider load downstream to upstream,please
following the steps...

*Calculate the Area(sqf or sqm)
*Calculate the load(lighting =1.5w/sqf,power=1w/sqf etc....)
*calculate the floor wise and get total load
*Applying the d.f and L.f and find the trf rating
*now you can design the MDB ,SMDB and FDB
