House Lighting Wiring Diagram Uk

With the progression of wiring standards over the years there are several electrical wiring colour coding used in homes around uk.

House lighting wiring diagram uk. Lighting circuits loop in loop out. Each protected by a 5 amp fuse or 6 amp trip in the consumer unit. This is a form of parallel wiring that has one cable usually twin and earth 6242y containing the live neutral and earth wires looping in and then out of leach light fitting. The first thing we need to understand is how to wire a light pendant.

Once you have read the safety tips a good place to start is by getting up to speed on the basic radial lighting circuit. All the light wiring diagrams are available in the old and the new cable colours to avoid confusion. The permanent live wire is wired into the switch and the switched live into the switched live terminal. Sometimes called a loop.

The earth wire which is located between the live and neutral wire provides a safe escape route for leakage current from a circuit as a result of electrical fault or poor connection. The second system in popular use is the junction box circuit or system. It is a modern way of wiring which reduces breaks in the cable and makes the work much easier and faster. Type one lighting circuit.

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. The neutrals are connected together using a terminal connector. The live is interrupted by the switch wiring and the circuit is carried on to the next junction box. 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. Power is taken from the consumer unit to the first junction box. The favoured way of wiring recessed downlights is using the loop in loop out method. A cable is run from the junction box to the light usually via a ceiling rose.

Let s break down the wiring to steps. Instead of taking the feed wire from the consumer unit to the ceiling rose it is taken to the switch.
