In case of single circuit instead of three circuits, if the load of a single storey increases, the more current will have to flow and cables may be overheated.

If you directly connect the over all load of different storys to the main breaker instead of separate main board, all the connected load (bulbs, fans etc) would disconnect in the whole building at once in case of tripping any circuit due to some reason (short circuit etc) which leads to trip the main switch.

Use separate main breaker for each storey and then distribute wiring in additional three or four main circuits in different sections.

Keep in mind that you have to follow the following instructions while installing single phase mains distribution in multistory building.

Now connect the RCD from DP with Phase (Line) and Related Neutral Link.Now connect the outgoing Phase and Neutral (L and N) from MCCB (Moulded Case circuit Breaker) to the DP (Double Pole MCB), RCD, SP (Single Pole MCBs and load) of each storey, as shown in fig).Check The below section for proper wiring color codes according to your area i.e IEC and NEC. Connect the MCCB (Moulded Case circuit Breaker) as a two pole main switch to the incoming Phase (or Live) and Neutral ( Land N) from 1-phase energy meter.if you aren’t sure that how to wire a three-phase energy meter, then check this simple tutorial which show How To Wire a Single Phase kWh meter ( Digital or analog Energy Meter). Connect the Neutral and Live Wire from utility pole in the first two input slots of single phase energy meter respectively as shown in fig 1. First of all, connect the single-phase energy meter to the mains supply i.e.To do single phase wring electric distribution system in a multi-storey building, follow the following steps. Sub-circuits and final sub circuits) in our previous posts, so follow the steps below to do the same as mention below. We have shown the basic electrical wiring of bulb, fans etc (i.e. Related Post: Different Types of Electrical Wiring Systems and Methods of Electrical Wiring Installation How to Wire Single Phase Main Distribution Board in Multistory Building?
