What is the point in wiring sockets in a ring, why can't you just put them on a radial ? What;s the benifits ?!

what and have a big 16 foot tall consumers unit? (one mcb for each socket)
wiring in a ring allows you to use two cables 'in parrallel' with each other thus aiding volt drop and current carrying capacity. 2.5 twin and earth has a ccc of about 26A (off the top of my head and dependent on how its installed) but running 2 in parrallel allows load sharing allowing you to use a 32A protective device.
this is why a broken ring is potentially dangerous, i.e you effectivelly have two radial circuits therefore a 32A protective device protecting a 26A rated cable...........potential fire risk.
a broken ring is only really going to be detected by testing too so the danger may exist and you dont know about it.
there is nothing wrong with radial circuits, they are a standard circuit, i.e 2.5mm cable with 16A/20A Fuse/mcb or a 32A protective device with 4mm wiring. radials are easier to fault find and test.
my old mentor always liked to use a radial for sockets in industrial environment and stayed away from rings. nothing wrong with either type as long as you design it correctly and consider the environment and purpose.

Sarcasm maybe, but I can see the advantage of a 16 foot tall consumer unit. Average height of 2 storeys in a house is 16 foot. No more fannying about with stupidly long circuits!
I like ring circuits.
They are imbued with a certain poetic symmetry and artistic merit you just don't find with a radial circuit.
