Wago DIN on Beneteau

[rubberduck]

Hello.

While i understand some basic electrical wiring I am by no means an expert but I'm trying to learn so forgive me if the question sounds a bit silly.

I'm trying to understand how the DC system is wired in my Oceanis 40. I understand is has a type of DIN from WAGO but beyond that I'm not sure how the current flow goes.

From the batteries I would guess the larger lines feeding in to the DIN (Wago) and somehow this power is then distributed among the different breakers feeding in to other distribution sites (if needed) around the boat... for example lights, etc or am i just way off here?

How is the panel controlling the on and off fiction of these different circuits?

If i wanted to replace the front panel to add some more switch options while keeping the DIN in the back is this possible?

I have googled DIN and WAGO but i'm not finding a good system wide explanation of how i can setup a system from scratch (so i can understand how the whole thing works) if anyone has some good resources it would be great to point me in the right direction.

Thanks in advance!
