What is a circular circuit?

The

circle of the circle is a power distribution method that sees every phase or line bridged from point to point across a number of stores and eventually arrives back to the same fuse, circuit breaker or connector from which it comes from. The circle of the circle is most often used for a single -phase installation conductor, but can also be found in three -phase power supply. The circular circuit, which is also known as annular or annular feed, came in the United Kingdom in response to a serious lack of copper that occurred after World War II. This connection method made it possible to use a smaller amount of cabling of a lighter meter and also stored on work. An unlimited number of outlets may include in the rings circuits, with the only restriction to the total floor area.

conventional home cabling of the home district consists of live, neutral and ground lines that are powered by consumer unit (Cu) oro Distribudeska (DB) to a number of stores. As soon as these lines reach the terminals, they are simply bridged from one to another until all the outlets are living neutral and ground connections. The total number of outlets on any given circuit depends on the capacity of the circuit breaker or the fuse from which they come from and their cumulative current evaluation. On the other hand, the connection of the ring of rings is live, neutral and ground lines, which are fed to a number of stores, and then return to the circuit breaker or fuse of origin, thus forming an uninterrupted ring.

6 Domestic districts in this fashion offered the advantage of requirements for lighter breakup cables and significant work savings. Having home districts also meant that if one "leg" of the ring failed, the other would still be able to carry a fair part of the burden. At the same time, the older round pipe plugs were replaced by the upper, types of flat pins that required the production of less copper.

In most domestic installations it was and is still a common practiceConnect each floor of a building with its own circular circuit and kitchen on a separate circuit. While the radial circuits have the final number of outlets that can support, circular circuits can feed any number of outlets, the only limitation is the total floor area powered by a circuit, which is generally 100 m ^{2 (1076 square feet). If additional outlets are required on the existing circular circuit, new additions are usually added using the "Spur" installation, which is simply a parallel extension from the nearest existing output. One of the disadvantages of the ring circuits is their low current tolerance and experience in difficulty in finding faults and proper load balance correctly. Multiple number of connected terminals also means circuit breakers of circuit feeding usually large and with a diameter is 30–32A.}
