Ring Within A Ring Circuit

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.

Ring within a ring circuit.

Within the electrical industry the ring main circuit sometimes ring main or ring final circuit is an electrical wiring technique that is most commonly used in the uk. Usually the protective devices used on a ring main will be a 30 a fuse 30 a breaker or 32 a breaker and the cables are usually 2 5mm in size. As described previously a ring circuit starts at the consumer unit connects to each socket outlet in turn and then returns to the consumer unit. Cable rating for cables used in a ring main must be no less than two thirds of the rating of the ring main s protective device.

A ring main or final circuit is exactly what it says on the tin. 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. The invention displays a guard ring within an integrated circuit design by determining positions of the logic devices within the integrated circuit design incorporating the guard ring into the integrated circuit design and displaying the logic devices and the guard ring either graphically semantically or symbolically in a single display. Ring circuit also known as ring main circuit.

Both blue wires connect to the neutral or n terminal. How does a final ring circuit or ring main work. All of the socket outlets will have two cables. A ring final has the potential for danger as do all incorrectly operating circuits and just about everything else in the electrical industry find some reasons why when the design of a ring is abused where problems can arise present them as potential problems for a circuit described as a ring but not installed or operating as such.

A ring final circuit or ring circuit informally also ring main or just ring is a wiring technique developed and used in the uk that uses two conductors for each of live neutral and earth to supply each connected socket or other load. The ring circuit is made up of two radial circuits connected to the same series of accessories within the circuit. Both brown wires connect to the live or l terminal. Ring circuits are wired with 2 5mm 2 cable and always have a 30amp fuse 32 amp mcb.

In practice meeting this requirement is rarely an issue. It gets the power from the consumer unit and delivers it to the sockets. Radial circuit converted to ring circuit. This design reduces the consequences of faults and enables the use of smaller diameter wire than would be used in a radial circuit of equivalent ampacity.

It is a ring of cables usually 2 5mm carrying twin and earth wires circling your home carrying the mains electricity to sockets on the way. The ring is fed from a fuse or circuit breaker in the consumer unit.
