Thanks Z … not criticising, just putting the complete picture.
It's a really difficult debate that's been circling round for much of my working life. I openly admit to having owned a CU in which I had a couple of “alien” mcb's in the past … and of course have used adaptable DIN rail boxes.
From a CU the manufacturer's perspective, if anything untoward were to happen in a CU, of course they would be looking at the best legal and insurance position for themselves.
As others have said, it would appear that you can put bits in a box and it's OK … but not when the box is a CU. But is that the entire story?
What standard is used for the assembly you've made when you put an mcb in a box? It can't be BS 7671 … see Regulation 113.1.
