Dude, your calculations are good.But you made big mistake!MCB protects cables, not the electrical divaices!MCB must be calculated based on cable gouge! If you have cable 2.5 sq/mm then you put 16a MCB, if 1.6 sq/mm then 10a MCB.If you will put bigger rate MCB you just simply burn your cables.
@@electricalpoint5852 what I ment is that Power Grid company gives you an Kw/h counter. And below it there is main MCB. whitch is sealed by the company. Then based on this MCB ratings you put your own MCBs on split-lines, and you put cable gouges according given main MCB and further split MCBs ratings.If you are not in ough of given power to your hosehold you have to ask the company for highier rating MCB.and then revire your cable system.For exeple to your hose is given 5kw, but you need 9kw .You ask power-grid company to give extra kws.Then insted of having 3 split cable lines you put 5.You do not put single cable in your house with 6 sq/mm gouge?

Cable size and MCB selection both are calculated taking the equipment as base rating. There is already video uploaded on cable size calculation.
