Shower circuit design.

Hmm. always ? 

How much worse is an MK breaker in a generic DIN rail box than say an MK light switch or fused  spur on a pattress or back box manufactured by AN-Other ? 

In the latter case we mix manufacturers and adopt responsibility at the drop of a hat.

Presumably the potential for  coming to grief is very Zs and PSSC dependent, as it should relate to how much the MCB comes to bits or ejects flames and hot metal drops during normal breaking operation - which really should not be that often . (cheese cloth tests)

I'd not condone the cropping of  bus-bar teeth, however  a short link of suitably rated cable should be perfectly OK if it can be done so it is making good contact at both ends. As an aside, it has often occurred to me that the DIN rail is a great mechanical standard, and what is really needed is  a second standard to define the plane of contact of the things  attached to it, but sadly that co-operation between makers is lacking.
