1st fix consumer unit installed a garage one rcd 2x mcb this was passed
2nd fix consumer unit garage one rcd 2x mcb this was passed

2nd fix distribution-boards

now is a distribution board a domestic consumer unit with main switch as it distributes the power round the circuits

Consumer units are a type of distribution board, but not all distribution boards are consumer units?

How much detail do you need for your question?
Yes consumer units are a form of Distribution board as you say, and perhaps your first go to place in search of answers - good habit to form - should be BS 7671. In this case the definitions section in BS 7671 - a reference source that the more you use the better you become with it plus useful as it sets out answers using correct terminology.

There you will see the phrase 'type-testing of the assembly' and it is within the BS en 61439 family of standards where further detail helps define
 
The only advise I can give is that that NVQ assessors are looking for the most comprehensive answer you can give, go into the minutia of everything you are answering, assume the assessor knows nothing and needs leading by the hand, they want a full description not a précis.
