Fair enough - so (not for the first time!) the wording of BS7671 seems a little on the silly side!

Fair enough. When I said 'mechanically compatible' I was talking about a situation in which they are dimensionally identical and "fit together" - but I don't doubt that that leaves some theoretical scope for more subtle types of 'mechanical incompatibility'.
If someone has some "facts", I would love to see them.
Kind Regards, John
To what tolerance?
I don't know if it has been decided before - but
do the manufacturers use the same criteria for there type testing (another silly phrase) and so all items could be mixed if they will fit - so they make them a different size so that they won't. That is, for example, all capable of withstanding a certain temperature next to them etc.
If not, some must be inferior to others. Which manufacturer uses the best type testing?

No doubt you would. Not sure about "facts", but I have some facts. Perhaps I'll post them when the court case finishes.
That might be interesting, but it presumably relates only to one incident. The facts I would be interested in seeing would be those relating to the incidence of serious problems due to mixed-make devices (which 'fit') in a CU.

I was waiting for that, and almost pre-empted it! I'm talking about 'common sense identical'.
Kind Regards, John
No such thing. Either they are within tolerance, or they're not. Fitting in the same space does not mean they are identical, or interchangeable.
This is, IMO, getting rather silly. We're not talking about critical parts in a jet engine or spacecraft.

No, it doesn't.
Well today I found the solution to the photo I posted earlier in the thread. The opposite way around though, Eaton into a Wylex board.
Gotta give the guy points for thinking outside of the box

That's creative!
In that case, it might be more interesting. How many incidents? A couple, a few, dozens or hundreds?

No comment. In any case, history is not a guide to probability.
Certainly is. Confusing AF though because it looks off when it's on and on when it's off.
