Hello. A little backstory, my house is a double storey Semi-D, currently on 1-phase, it's a 20+ years old house, 1 DB box at ground floor, 1 at 1st floor. As we do not have the budget to change to a bigger DB box, or to 3-phase.

My electrician recommends that to evenly spread out the electricity and have enough electricity for the entire house, by default there is already 2 DB BOX, one at the ground floor, one at the 1st floor, electrician recommends us that he will add 1 more DB BOX at the ground floor kitchen area, so the electrical appliances like fridge and washing machine, ground floor aircon and so on, will connect to this new DB BOX located at the back kitchen, so in total there will be 3 DB BOX. Is this method a better option and does it work like that ?

P/S - Not that I don't trust my electrician, I do, but I'm just seeking for 3rd party opinions, just to be on the safe side, because that extra DB box alone will costs 850.
