Selective pedantry, perhapsI notice 'transformer' seems to be treated leniently here. Why not the other two?
An ELV lighting power supply does transform voltage.
From BS 7671 (with my emphasis):Fuse boards and consumer units are different.
Tell me why not? It's PERFECTLY acceptable. There are times when a fuse is preferable over an MCB, but the rest of the installation would be MCBsA Pic-N-Mic board! Ha ha
p.s. you should NOT really have MCBS and cartridge fuses on the same din-rail - it is unnecessary to mix and match - it just looks so Awful!
Dunno. Is it type-tested to EN 60439-3?i hate to join in, but what's an enclosure that contains MCBs and cartridge fuse carriers in one called?
