Some guy in the office said the regulation method of UK house wiring is now a separate spur from each socket back to the CU with an MCB per spur. This is the method that's popular on the continent e.g. France. It means a heck of a lot of mains cable is used and a HUGE CU is required; fuse per socket. On the other hand the mains flex used doesn't have to be as thick as normally used on a ring installation. Also he says that twin-and-earth is no longer used with individual separate wires running from each socket back to the CU. Is this right?
