Is that permitted by the manufacturer's instructions for either Doepke or Hager?Hager MCB's and RCBOs will fit Doepke boards, the latest type with the wide light grey lever.
Well said! I really think that BS7671 (and other standards/regulations)ought to find some way to avoid being an accomplice to restrictive practices by manufacturers. In other words, it should find a way to distinguish between MIs which are there for good engineering/safety reasons, and those which are there primarily to increase the manufacturer's sales!
In common sense terms, I don't think anyone can disagree with that - although the pedants would presumably still say that is was strictly non-compliant with BS7671 if the MI had indicated that only their own MCBs should be used.
My opinion is that I would hate to see something like a Chint MCB shoved in a nice MG board
Yes, but that type testing, which is what is being used as an excuse for the restricted practices, would become a complete joke if standards for MCBs insisted that they had to conform to dimensional standards (of terminal positioning, as well as casing and fixings) - after all, as per the comment which started this tangent, a 'CU' is nothing more than a plastic box with a DIN rail in it!My opinion is that I would hate to see something like a Chint MCB shoved in a nice MG board
At least when you install a consumer unit with the same manufacturers MCBs you know it has been fully type tested.
