Generally with a small consumer unit you will have 2 copper strips - one is for the earth (green/yellow) and the other for the neutral (blue).
Terminal strips more likely Brass or Aluminum..
They will not have any colour identification until you attach some sticky terminal label numbers that should come with the unit.
The individual circuits connect into the bottom (usually) of the MCBs. The live/line/phase (whatever they call it this week, brown in colour) connect to the main switch or RCD that then put power into the bus bar - the metal bar the MCBs are attached onto.
The outgoing side where you connect your circuit cables is the TOP of the MCB..
The bottom is the incoming side from the main switch.
Some consumer units come with a neutral link from the solid neutral bar, sometimes you need to create one with suitably sized cable.
All consumer units come with a pre formed link/flex to connect the neutral bar to the outgoing neutral of the main switch.
And a solid bar to connect the MCB's to the outgoing live of the main switch.
Ensure where the cables enter that little fingers cannot poke through.
Sheath any exposed earth cables in green and yellow sleeving.
Try to keep things neat and keep the circuits in order (so first MCB, neutral in position 1, earth in position 1). It will work if mixed up, but messy to test and fault find.
I will update your account so you can see and post links.
