How to feed garage board

[Bradley6969]

First fixed X6 new double sockets in garage the other day (didn’t have sockets to 2nd fix) now it’s TT system, now the board I’m working on is fed from a bigger garage 2.5mm SWA 16A RCBO, the board where I have first fixed the sockets has a Main switch and MCB for lights and sockets,

Would it be best to swap RCBO for MCB to feed the board I’m working on and just RCBO for lights and RCBO for sockets, im sure the Main Switch/RCD for the site is 300mA upfront so all good there.
Thanks

I'd leave the way it is to be honest.

RCBO's in the garage would be nicer, save loosing the lights also if you end up plugging something in with an earth fault. However, it's an extra cost.

Explain the advantage to the client an let them make the decision.

Yeah I guess so, the only problem if there is a fault the main board with RCBO will trip and it’s in another garage but I suppose it could trip if I changed it to an MCB on short circuit so I’ll possibly leave how it is actually.

Do what ever is cheapest (yes I’m a cheapskate)

Leave it as it is, there's no discrimination between the ocpd for the submain and the final circuit ocpds so presumably someone has already made the decision that there's no problem with the whole lot going off under fault conditions.
