Explanation:
The ring is fed from a fuse or circuit breaker in the consumer unit. Ring circuits are commonly used in British wiring with socket-outlets taking fused plugs to BS 1363. Because the breaker rating is much higher than that of any one socket outlet, the system can only be used with fused plugs or fused appliance outlets.
