How To Wire A Lighting Circuit Uk

Once you have read the safety tips a good place to start is by getting up to speed on the basic radial lighting circuit.

How to wire a lighting circuit uk. One way lighting circuit using in line switching. Also if we control each lamp by single way spst single pole single through switch in parallel lighting circuit we will be able to switch on off each bulb from from separate switch or if we switch off a bulb the rest lighting points won t affected as is it happens only in series lighting connection where all the connected load would be disconnected. A cable is run from the junction box to the light usually via a ceiling rose. Usually the light base or pendant provides all the terminals necessary to wire up the lighting circuit.

Once you have mastered the basics. The permanent live wire is wired into the switch and the switched live into the switched live terminal. Power is taken from the consumer unit to the first junction box. The first length of cable will be from the supply to the light itself.

This is an alternative way of wiring a lighting circuit. The second system in popular use is the junction box circuit or system. The cable going to the light switch is connected as follows fig 2. Once connected the light pendant should look like this click to enlarge.

A one way light switch is quite easy to wire up. You must use the brown slewing to indicate the switched line wire. Faults in parallel lighting circuits. The first step is to wire up the light pendant.

The red wire from the feed cable is connected to the top terminal the red wire going to. Line diagram of a one way lighting circuit using in line method fig 1. The live is interrupted by the switch wiring and the circuit is carried on to the next junction box. Instead of taking the feed wire from the consumer unit to the ceiling rose it is taken to the switch.

Each protected by a 5 amp fuse or 6 amp trip in the consumer unit. If this is not the case push in or strip connectors are the preferred way of connecting up the circuit. Sometimes called a loop in circuit this shows how power is distributed around the lighting circuit via the ceiling roses or junction boxes and how to wire a light switch into the circuit. This is how you wire a light pendant.

The neutrals are connected together using a terminal connector. Here you can see there is a cut in the line wire connected to lamp 3 so the bulb is switch off and the rest circuit is working. 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. In modern domestic properties in the uk the main electric lighting circuits are separate from the power ring main circuit.

Without it the blue wire indicates a neutral wire. Type one lighting circuit.
