Simple Lighting Circuit Diagram Uk

Here is an example of a simple circuit diagram using a cell and a light bulb.

Simple lighting circuit diagram uk. Earth wires are not shown. However the fact that there is a switch included does seem to cause issues particularly when someone has purchased a fancy new light fitting from b q pulled down the old ceiling rose and then finds 9 wires in the ceiling and only 3 connections in the new fitting. The cable going to the light switch is connected as follows fig 2. Radial circuits are used for lighting there is one lighting circuit on each lighting mcb lighting circuits are usually on a 6a mcb or 5a fuse though 10a can be used with some extra restrictions now removed in the 17th edition of the wiring regs for large circuits however if the area served is large more 5a or 6a circuits would in most cases be preferable.

Lighting circuits are not usually complex or difficult to understand. Each house should ideally have at least two lighting circuits. Each protected by a 5 amp fuse or 6 amp trip in the consumer unit. A single 5 6 amp circuit can cope with up to twelve 100 watt lamps it is usual in a multi.

Power is taken from the consumer unit to the first junction box. L and n indicate the supply. One way lighting circuit using in line switching. The second system in popular use is the junction box circuit or system.

A cable is run from the junction box to the light usually via a ceiling rose. The most basic circuit with only two wires at the switch. So before we get stuck in to some wiring diagrams. In modern domestic properties in the uk the main electric lighting circuits are separate from the power ring main circuit.

All the light wiring diagrams are available in the old and the new cable colours to avoid confusion. A one way light switch is quite easy to wire up. If this is the case then it is either the last light on a loop in circuit or the connections could of been made in a junction box and then a single cable has been run to the ceiling rose or the lights could of been wired with the neutral wire in the switch instead of being in the ceiling rose. The red wire from the feed cable is connected to the top terminal the red wire going to.

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. Line diagram of a one way lighting circuit using in line method fig 1. Type one lighting circuit. These diagrams show various methods of one two and multiple way switching.

Switches are shown as dotted rectangles. The live is interrupted by the switch wiring and the circuit is carried on to the next junction box. Wring a simple lighting circuit might be an easy enough process for a qualified electrician and with a little determination anybody with basic skills can do it. We use circuit symbols to quickly draw circuit diagrams with straight lines to show the wires.
