Yes it does, and it is not.
The standard in question, where the term "switchgear assemblies" is used, is BS 7671. Where is that clearly defined in BS 7671?

Indeed - Who would go through all of that for a one-off custom "box-o-tricks" for his own home? The process would be tedious and far too expensive.
Furthermore.....
For that one-off home-built "box-o-tricks" in one's own home? I don't think so. If I were still in England and installing such a unit in my own home, surely the only legal requirement would be that it is reasonably safe?
421.1.201 Within domestic (household) premises, consumer units and similar switchgear assemblies shall comply with BS EN 61439-3....

But arguments about what "similar switchgear assemblies" includes aside, as you're both well aware there is no legal requirement to follow BS7671, so anything within BS7671 which says the "box-o-tricks" must comply with BS EN whatever cannot be a legal requirement either.
Nobody is saying that it is.
Not true, if there is a legal requirement that is not within BS 7671.
Your box full of raspberry pies, arduinos, etc is not within the scope of the standard for switchgear and controlgear assemblies.
So if I were still in England and wanted to install my own custom "box-o-tricks" in my own home, where is the legal requirement for it to comply with BS EN-whatever?
You might have noticed that I was talking about manufacturers. The requirement to demonstrate conformity only applies if the equipment is used "in connection with a business", so if you make something for your own use, in your own home, you only need to make sure it is safe. However, if you intended to use it to demonstrate your ability to make such a 'thing', in the hope of selling more of them, then I suppose it would fall under the Regulations.
I did write "if".
Not quite - stillp added the emboldening (to what you had written) to make his point.
Kind Regards, John
OK - sorry.
So what does "and similar switchgear assemblies" in 421.1.201 mean?
If the scope of BS EN 61439-3 is relevant to 421.1.201 does that mean:
a) We can use BS EN 61439-3 as a guide to what "non-combustible" means?
b) I could indeed assemble my enclosure, MCBs, RCBOs, RCDs, switches, E & N distribution blocks etc and use it in place of a CU and not have to worry about 421.1.201 because that distribution board is not similar to a CU?
