I understand the reason for the ring circuit to return to the CU to be the following:
"In electricity supply, a ring final circuit or ring circuit (informally also ring main or just ring) is an electrical wiring technique developed and primarily used in the United Kingdom that provides two independent conductors for live, neutral and protective earth within a building for each connected load or socket.
This design enables the use of smaller-diameter wire than would be used in a radial circuit of equivalent total amperage. Ideally, the ring acts like two radial circuits proceeding in opposite directions around the ring, the dividing point between them dependent on the distribution of load in the ring. If the load is evenly split across the two directions the amperage in each direction is half of the total, allowing the use of wire with half the current-carrying capacity. In practice, the load does not always split evenly, so thicker wire is used."
Iv just run the wires in my electrical install and i have the lighting circuit returning to the CU which i now understand is wrong.
Can someone explain why we do this for the ring circuit and not for lighting?
thanks in advance guys.
