Simple Lighting Circuit Diagram Uk

Power is taken from the consumer unit to the first junction box.
Simple lighting circuit diagram uk. One way lighting circuit using in line switching. Here is an example of a simple circuit diagram using a cell and a light bulb. Switches are shown as dotted rectangles. So before we get stuck in to some wiring diagrams.
These diagrams show various methods of one two and multiple way switching. 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. Each protected by a 5 amp fuse or 6 amp trip in the consumer unit. Lighting circuits are not usually complex or difficult to understand.
A cable is run from the junction box to the light usually via a ceiling rose. The red wire from the feed cable is connected to the top terminal the red wire going to. The live is interrupted by the switch wiring and the circuit is carried on to the next junction box. You may find that there are only a few wires in your ceiling rose.
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. Line diagram of a one way lighting circuit using in line method fig 1. In modern domestic properties in the uk the main electric lighting circuits are separate from the power ring main circuit. The second system in popular use is the junction box circuit or system.
A single 5 6 amp circuit can cope with up to twelve 100 watt lamps it is usual in a multi. First let s have a look at this wiring diagram describing a lighting circuit in its most basic form. 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. Each house should ideally have at least two lighting circuits.
L and n indicate the supply. Earth wires are not shown. 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. The cable going to the light switch is connected as follows fig 2.
All the light wiring diagrams are available in the old and the new cable colours to avoid confusion. 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. Type one lighting circuit. The most basic circuit with only two wires at the switch.
