I shall be "out of the office" for the next 8 days and no doubt this debate will continue.
Just a couple of points:-
If you buy an enclosure plus various separate DIN rail mounted devices from a Wholesaler and you make a hash of the assembly, nobody would think the Wholesaler was the manufacturer.
Since none of my current product range bears the SBS logo, I don't think the "scared" bit is relevant. I am a Distributor, not a Manufacturer.
When I return to the Forum, I am sure Super will have posted a photo of one of his installs, to show how a DB should be wired.
In that way, many Forum Members, myself included, will benefit from his "teaching by example".
Good night to you all. I've got an early start tomorrow.
