Diagram of a possible configuration of ring final circuit. Consumer unit is at bottom left. The ring starts at the consumer unit (also known as fuse box, distribution board, or breaker box), visits each socket in turn, and then returns to the consumer unit. The ring is fed from a fuse or circuit breaker in the consumer unit.
Ring (or ring final) A ring final circuit is similar to a radial except what would be the end of the circuit instead loops back to the source protective device in the distribution board. Thus each individual conductor, line, neutral and earth, actually forms a loop (or ring), from the source, out, and back around to the source again. This has ...
Wired connections may also be connected to the final ring, requiring to include a suitably rated fuse and switch. The final ring circuit in the UK requires the use of BS 1363 plugs and sockets. However, the BS 1363 system is not limited to use with final ring circuits being suitable for radial circuits. [44]
In an electrical power distribution system, a ring main unit (RMU) is a factory assembled, metal enclosed set of switchgear used at the load connection points of a ring-type distribution network. It includes in one unit two switches that can connect the load to either or both main conductors, and a fusible switch or circuit breaker and switch ...
