    In electricity supply, a ring final circuit or ring circuit (informally also ring main or just ring) is an electrical wiringtechnique developed and primarily used in the United Kingdomthat provides two independent conductors for live, neutral and protective earth (ground) 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 circuitof equivalent total current. 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 current 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.

    since the ring circuit have 2 drench in a live wire,

    it can distribute the electrical appliance to difference socket,to decrease the loading of one socket,

    it can prevent overloading.

    In a ring circuit, current is delivered to an aplliance in two separate paths, one is clockwise along the ring and the other anticlockwise. In such a way, the current flowing in the ring can be reduced to half of the maximum consumed current of the given appliance. Thus preventing the circuit from overloading.
