I regularly use Wago TopJob DIN rail connectors for CU replacements, if the cables need extending.
As a slight twist on the metal consumer unit debate, how many of you will be happy to fit connectors (DIN rail or otherwise) in a plastic adaptable box to extend cables when installing a metal-clad consumer unit? It doesn't seem to fall into the category of "consumer units and similar switchgear assemblies", and if we need a metal enclosure here, where do we stop? Cooker and shower isolators next?
Of course, there's a vast difference between the "vibration proof, maintenance free" TopJob connectors and some cheap, poorly installed connector block.
