I am working on a commercial building having small shops. As Each shop should have panel board and from where the main cable will go to meter room. Now i am providing two circuit breakers one for light and other for power. Now what will be the structure of panel. Shall i need to put three phase wire and give two wires to two breakers keeping one spare or two single phase wire should be run to meter board. The second case don't look practical.

If the 2 ckt sub panels are code compliant no need to run 3 phase for those small loads
run 3W w/gnd, L1, L2, N, G
each sub panel ckt on a line

if the main panel is 3 phase the single phase sub panels will balance out because the 2 pole breakers are staggered

How can we connect it to the metre panel then.
We have 400/230 voltages. I think it's not permitted here. And there will be problem in phase balancing also.

The meter bank can be 3 ph in and single ph out
they are staggered
so it will balance if each sub panel is loaded about the same

your lighting and receptacle ckts are 230 to N correct?

Yeah 230v phase to neutral for light and receptacles.

I have other idea, i will provide double pole incomer on single phase. It will provide to two following circuit breakers seperately. Thus i have to run one phase to meter room.
