Ring Main Lighting Circuit Diagram

As you can see the circuit starts and ends at the consumer unit.

Ring main lighting circuit diagram. A main isolating switch. All the light wiring diagrams are available in the old and the new cable colours to avoid confusion. This switches off everything. 2 way light switch 3 wire system new harmonised cable colours.

The single way lighting circuit is the simplest of the lighting circuits and consists of a source a switch and a bulb. When the switch is in the on position it completes the circuit and supplies power to the lighting fixture when the switch is changed over into the off position. 10a lighting circuits are occasionally used. As you can see a basic lighting circuit consists only of three components.

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 this design enables the use of smaller diameter wire than would be used in a radial circuit of equivalent total current. 20a radial socket circuits. In order to energise the light we need to connect it to the supply available. Multi point radial lighting circuit new cable colours multi point radial lighting circuit old cable colours old multi point radial lighting diagram using junction boxes.

In most cases at least one rcd. Type one lighting circuit. We have and extensive collection of common lighting arrangements with detailed lighting circuit diagrams light wiring diagrams and a breakdown of all the components used in lighting circuits. A cable is run from the junction box to the light usually via a ceiling rose.

So before we get stuck in to some wiring diagrams. Supply switch and light. The diagram is shown with 6a lighting fuse and 32a ring circuit mcb. Each protected by a 5 amp fuse or 6 amp trip in the consumer unit.

Please observe the wiring diagram above. This is usually a distribution board of some sort. Power is taken from the consumer unit to the first junction box. Other options are also possible.

In modern domestic properties in the uk the main electric lighting circuits are separate from the power ring main circuit. A single 5 6 amp circuit can cope with up to twelve 100 watt lamps it is usual in a multi. A single pole switch is the simplest form of electrical wiring. Consumer unit cu the consumer unit previously called a fusebox contains these things.

Basic multi point radial lighting circuit. Use a multi meter to test for a radial or ring main final ring circuit available from our online store here even though the sockets are connected to two cables or 2 5mm and supplied by a 32 amp fuse or mcb it cannot be guaranteed that it is a ring main or final circuit. Each house should ideally have at least two lighting circuits.
