What Is A Ring Main In A House

Its simplicity makes it a great arrangement for that use.

What is a ring main in a house. 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. The ring main is connected to the consumer unit on both ends which helps lighten the load on the wires. 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. In electricity supply design a ring final circuit or ring circuit often incorrectly called a ring main a term used historically or informally a ring is an electrical wiring technique developed and primarily used in the united kingdom and to a lesser extent in ireland this design enables the use of smaller diameter wire than would be used in a radial circuit of equivalent total current.

Hi ericmark maximum cct length for the ring cct would be 4 x 11 5 x 1000 32 18 79mtrs. The main purpose of a spur is adding an extra socket on to an existing ring main circuit. The correct terminology for ring main is either final ring circuit or ring circuit however now you know that we will continue to refer to it in the most common parlance as seen all over the internet. As you can see it eliminates the need to wire a socket all the way back to the a consumer unit but the nearest ring main socket is used instead.

I guess this is a fairly non trivial task. Extending a ring main and adding more sockets to a room. 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. A ring main brings electricity from the consumer unit through the house.

Ring main is a term which has been used for years and will continue to be used for many more years but it is incorrect it s just easy to say. So 4 x 11 5 26 18 98mtrs. How to extend a ring main and add sockets to the ring main. If it assumed to be 20a at the far end and an additional 12a is evenly distributed the average current is 32 20 2 26a.

However in a ring circuit the current in the ring will not be the same all around the ring. This project shows you how to put more sockets in a room or office if you need to add to what was originally installed. The wiring in a house connects all appliances together in parallel. Electricity loses power as it travels over long distances.
