Follow this link if you are looking for a comprehensive step-by-step guide on two-way and intermediate lighting circuit wiring.
2 way lighting circuit wiring diagram uk. Two way light switching 3 wire system new harmonised cable colours NOTE. Your lighting circuit must have an earth cable terminating in the switch back box and also at the switch plate if it is metal. The other end of the Lamp is connected with the Neutral line of AC power supply.
Each house should ideally have at least two lighting circuits. Otherwise continue with the AM2 exam guide. Two way switching 2 wires.
Cable D Fig 2 is a three core and earth this is the 3 wire control that links the two light switches together. These diagrams show various methods of one two and multiple way switching. 3 way light switching new cable colours 3 way light switch old cable colours 3 way light switch using a two wire control.
L and N indicate the supply. This diagram shows the additional cable connected to an existing ceiling rose. The other end of this cable is taken to the position of the new light.
The most basic circuit with only two wires at the switch. Instead of taking the feed wire from the consumer unit to the ceiling rose it is taken to the switch. Below is the way I like to do it.
To add a second light which is switched with the first one the switched line neutral and earth need to be extended to the second light. As a part of the AM2 exam you will have to wire up a 2 way and intermediate lighting circuit with one light. Fig 2 The feed cable comes from a previous junction box or from the consumer unit the red black and earth wires are connected to separate terminals.
2 Way Light Switch Wiring Diagram Uk from wwwlightwiringcouk. 2 way light switch 3 wire system new harmonised cable colours 2 way switch 3 wire system old cable colours 2 way switch two wire control Three way switching. The Grey wire in cable D is a switched live and the Blue wire in cable C and Black wire in cable D are permanent lives.
All earth wires should connect to the earth terminal in the switch back-box and if you are using metal switches there MUST be a loop from this earth terminal to the one on the switch plate see note A on. It is a modern way of wiring which reduces breaks in the cable and makes the work much easier and faster. Removing Existing Light Fitting When you have removed your existing light fitting and are faced with a mass of cables hanging out of the ceiling life is a little dauntingBut it is not as complicated as it looks.
A two way switchuk Schematic diagram of old wire colours. In modern domestic properties in the UK the main electric lighting circuits are separate from the power ring main circuit. How to wire 2 way light switch in this video we explain how two way switching works to connect a light fitting which is controlled with two light switches.
The red wire from the feed cable is connected to the top terminal the red wire going to the light is connected to the bottom terminal the black wires from both cables are connected together in a plastic terminal block and the earth wires are connected to the earth terminal. Connect the blue wire with the brown slewing coming from the light to the L2 terminal together with the 3 CoreEarth cable grey wire. 2 way lighting circuit diagram 2 way switch 2 way switch wiring diagram electrical wiring how to wire a light.
Two way light switching schematic using a two wire control Downside s of the two wire control system. Line diagram of a two way lighting circuit using junction boxes fig 1. The new cable here is labelled light 2.
The cable going to the light switch is connected as follows fig 2. 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. Once you have mastered the basics we take a look at the two way switch arrangement.
2 Way Light Switch Wiring Diagram Uk. The neutrals are connected together using a terminal connector. Each protected by a 5 amp fuse or 6 amp trip in the consumer unit.
This is an alternative way of wiring a lighting circuit. Explanation of above picture. PIN1 of both the switches are connected with the phase or live wire and PIN2 of both the switches are connected with the one end of the lamp.
Schematic diagram of new wire colours. Connect the Line brown wire coming from the light together with the 3 CoreEarth cable black wire in to the L1 terminal of the two-way switch. For example if a module is powered up and it sends out a signal of fifty percent the voltage in addition to the technician will not know this he would think he has an issue as he would expect a 12V signal.
There is more than one way to do this depending of the type of cable available and on the installation requirements. You are most likely to see this 2 way lighting circuit in an industrialcommercial setting where the installation is trunkingconduit based and single core conductors are used. As you can see in the Schematic Diagram of 2 way switch circuit below the common of both the switches are short-circuited.
For two and three way lighting diagrams which can be identified by additional yellow and blue wires within the lighting switch cables follow the link. COM on the first switch connects to COM on the second switch L1 on the first switch connects to L1 on the second and L2 on the first switch connects to L2 on the second. Effectively read a electrical wiring diagram one has to learn how the components inside the method operate.
The permanent live wire is wired into the switch and the switched live into the switched live terminal. This wiring diagram shows how all houses and most of commercial lighting installations are wired these days. The junction box should be wired as shown below.
Earth wires are not shown. The way I show allows you to fairly easily add a second two way switch to an existing light switch by simply wiring them together in a certain way.
