What Is Ring Circuit Wiring

A single ring can replace at least two radials and.

What is ring circuit wiring. 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. They are not so common in the uk but are used extensively abroad as the ring main or final ring circuit does have it s drawbacks. The other type of circuit used to power your home is a radial circuit. The ring circuit is made up of two radial circuits connected to the same series of accessories within the circuit.

In essence three things 1. 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. A ring circuit is a uk standard means for wiring domestic and other light commercial premises not often seen elsewhere in the world. In practice meeting this requirement is rarely an issue.

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. In general it requires less cable as there are two parallel routes back to the consumer unit distribution board which allows thinner cable to be used for the same load. A ring circuit is a power distribution wiring method that sees each phase or line bridged from point to point across a number of outlets and eventually arriving back on the same fuse circuit breaker or bus connector it originated from the ring circuit is most commonly used to wire single phase installation but may also found in three phase power supplies. In effect it is a radial circuit whose final termination is made back to the originating distribution board rather than at the last outlet or device serviced.

A radial circuit is where the feeders to each socket or sockets are taken directly from the consumer unit and in europe the circuit protection at the consumer unit is a 20a mcb or rcbo. Due to safety a typical ring main circuit use for a 230v ring main 32a circuit breaker cb and 2 5mm cable what is double rating compare to radial circuit. Wiring a radial circuit in this diy guide you will learn how to wire up a standard radial circuit and also ensure that it is safe by using the correct size of cable and also the correct mcb in the consumer unit. A ring circuit has two feeders which both come from the sam.

The ring is fed from a fuse or circuit breaker in the consumer unit. Radial circuit wiring material cost is more less than ring main circuit. 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.
