Ring Main Lighting Circuit Diagram

Please observe the wiring diagram above.

Ring main lighting circuit diagram. 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. 20a radial socket circuits. Basic multi point radial lighting circuit.

As you can see a basic lighting circuit consists only of three components. The single way lighting circuit is the simplest of the lighting circuits and consists of a source a switch and a bulb. Supply switch and light. It goes around the house or a room and connects to all the sockets and fused connection units fcu s required to be on the ring main circuit.

This is usually a distribution board of some sort. Other options are also possible. The diagram is shown with 6a lighting fuse and 32a ring circuit mcb. Power is taken from the consumer unit to the first junction box.

A main isolating switch. So before we get stuck in to some wiring diagrams. The second system in popular use is the junction box circuit or system. 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. All the light wiring diagrams are available in the old and the new cable colours to avoid confusion. This switches off everything. In order to energise the light we need to connect it to the supply available.

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. Consumer unit cu the consumer unit previously called a fusebox contains these things. 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. In modern domestic properties in the uk the main electric lighting circuits are separate from the power ring main circuit.

Each house should ideally have at least two lighting circuits. The live is interrupted by the switch wiring and the circuit is carried on to the next junction box. Each protected by a 5 amp fuse or 6 amp trip in the consumer unit. 2 way light switch 3 wire system new harmonised cable colours.

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. As you can see the circuit starts and ends at the consumer unit. A cable is run from the junction box to the light usually via a ceiling rose.
