That's just an RFC with multiple spurs, mothing odd about that methodWhat about option 4 - Hedgehog. RFC with loads of spurs?

and no doubt a proliferation of fire nuts. on another forum, predominantly American, several members praise their silly wire nuts and condemn wagos.People think rings are bad , I recently watched a video of a guy wiring his house in America and he put lights and sockets on the same circuit using the same sized cable and kept calling it ‘roughing’ in his wiring...
it was blooming rough and at every point he stripped the cores back & twisted the bare copper earths together and shoved them in the back of each box so he had just the L & N to connect later

Yeah, I was watching the ideal international sparky championship. Aussie, Canadian, American and a Chinese fella in the final. Someone in the comments section asked where the British entry was. The comments were “Anyone who uses Rings, are not invited” and the like. These foreign morons have no idea of the concept. They probably would have trouble wiring one.
The problem with properly verifying a ring is not lost on a radial either (for the record, I think spurs off a ring are the Devil's work and should be you last resort).Real time constraints when carrying out EICR's at acceptable cost mean ring circuits are often not properly verified and the inspector has to make judgement calls on whether the circuit is correctly wired. That said I love testing my own rings and calculating whether measured readings are spot on!
As far as radials go there was a long thread on here a while back where an OP stated rings should be outlawed because they are often abused by Kev the kitchen fitter and DIY Dave, his point was radials are much safer.
But unskilled persons being unable to correctly alter a ring is not a reason for banning it, ban Kev and Dave...not the ring!!
That point of view also ignores the potential danger of a radial. One bad or broken connection of the cpc may result in every downstream point working and apparently ok but not having an earth.
Indeed, and one of my bugbears on this forum is those who advise punters to have an EICR because it will identify any problems. No it wont necessarily.... and those of us tasked with carrying out EICR's are not helped by the creation of unrealistic expectations of what an EICR can identify.The problem with properly verifying a ring is not lost on a radial either (for the record, I think spurs off a ring are the Devil's work and should be you last resort).
Say you have a 32A radial in 4mm, how often would an EICR check it had not been extended in 2.5mm for much the same risk as a double-spur on a ring?
Yes, the usual radials on 20A might be safe for 2.5mm but it is the same underlying problem - if some idiot has extended a circuit badly it is not always apparent from the readings.
I guess checking the worst case Zs is OK for the MCB is probably good enough for most cases, but complete verification of an unknown is a costly and difficult situation in both cases.
I don't quite understand that statement.I think the ring is for the more technical minded. The maths in it are great. Really it is not for amateurs so I can see why dumbing down is the way to go as with so many things today.
