That's true but, to be fair, the only really contentious aspect (and main perceived advantage - other than redundancy of CPCs ) of ring finals is the 'dispensation' which allows a cable to be protected by an OPD with an In greater than the cable's Iz/CCC. In the absence of that 'dispensation' (i.e. if all 32A sockets circuits had to be wired with ≥4mm² cable), I doubt that many people would bother (or think) to wire those circuits as rings, would they?Your comments relate to the relationship between the CCC of the cable and the choice of protective device, not to the choice of a radial or ring.
