That's fine but i wasn't arguing that RoW uses radials because they can't use rings; more that the fact they don't use them proves they're not needed to install perfectly safe and operational installations. Rings are simply unnecessary.
They are not
necessary. Neither are radials either.
But the RFC is efficient and effective for its intended purpose of general sockets around a larger area, it also lends itself to better fault coverage during testing.
The same logic can be applied to parallel feeds. They are not
necessary but if you have every had the misfortune to try and wrangle cable like 120mm and above you would be cursing the designer for not use two that are not quite so " anaconda on ------" to deal with.
I also think it's preferable to have different rooms or different sections of the home on different breakers. We're encouraged to split between floor levels but imo splitting between sections or rooms is much more preferable.
It is a trade-off. How much more effort in running each circuit back to the CU? How much more cost in the RCBOs (or coming soon for a small premium AFDD for all)?
Also how often do you meet an installation with a fault in the fixed wiring that is not a direct result of botched DIY? It happens for sure, but probably less than faulty appliances.
And this leads back to another less considered aspect of the EU versus UK plugs. With fused plugs if there is a hard fault then often the fuse will go as well as the breaker tripping. Reset the breaker and all comes back on except the faulted appliance as it has been isolated by its fuse blowing.
With unfused EU plugs you would need to either know which on has faulted, or unplug all and go round plugging them back in until BANG!
That is another nice aspect of UK sockets, though sadly underused, they are (usually)
switched. So you can plug in and switch on and have less of a brown trouser moment of plugging in to a live fault should it occur.
Finally on the UK sockets, they have the safety shutter that is lacking in most of the rest of the world. True, the determined child or idiot can defeat that protection but it raises the bar somewhat to poking stuff in to holed to find out what happens...
