Wiring A Lighting Circuit Diagram. Wire a Switched Outlet. L and N indicate the supply.
This 3-way light switch wiring diagram shows how to do the light switch wiring and the light when the power is coming to the light fixture. The live is interrupted by the switch wiring and the circuit is carried on to the next junction box. The L Line also known as live or phase is connected to the first lamp and other lamps are connected through middle wire and the last one wire as N Neutral connected to the supply voltage then.
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.
Want to turn a lamp on with a light switch. Instead of taking the feed wire from the consumer unit to the ceiling rose it is taken to the switch. The grounding conductor in the cable is not shown in order to simplify the diagram. Sometimes it is handy to have an outlet controlled by a switch.
