In domestic when the Zs easily low enough why do we default to have type B instead of C curve MCB's/RCBO's

I don't think designed more suitable for the load.Type B is designed for domestic use.
Type B is designed for domestic use.
In the days of predominate tungsten lighting I always fitted C 6A on lighting to prevent nuisance tripping from a failing lamp. B or C is mindset providing ADS is provided it is totally irrelevant.
Both will trip in the same time if the current is enough to cause instantaneous operation.Type B will respond better/quicker to an overcurrent so surely the better option when you don't have to allow for inductive loads or startup current for example.
I don't actually know what you mean.Ok. Not soley for domestic but you know what I mean.
There is little in a domestic that requires a Type C.
Installing MCBs that trip at 5-10 times the current rather than 2-3 times should not be installed unless required.
Having a few LED downlights will not require a Type C.
There is no line of separation between a so called domestic protective device and a device for other purposes, it is mindset.
The product standard is EN60898 or EN61009 it is the type characteristics which define the intent.Are the different product standards not a line of separation ?
