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 circuits are commonly used in British wiring with socket-outlets taking fused plugs to BS 1363. Because ...
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 ...
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 ...
One of the other recommendations in the report was the introduction of the final ring circuit system (often informally called a "ring main"). In this arrangement a cable connected to a fuse, or circuit breaker, in the distribution board was wired in sequence to a number of sockets before being terminated back at the distribution board, thus ...
The ring main is located well below most water mains, at a depth of 10 to 65 m (33 to 213 ft) below ground level and approximately 10 to 30 m (33 to 98 ft) below sea level. The tunnel is mostly of 2.54 m (100 in) internal diameter, except for the section between Ashford Common and Kew, where it is 2.91 m (115 in). [ 4 ]

OK, that's about a gas "main" rather than an electrical one, and the term was chosen to make the rhyme. But the point is, mains power is what laymen call the stuff that comes out of power points, and the mains is the wiring behind them, and a ring main is what they commonly call the technique described in this article when it's in their home ...
