Wiring Diagram 2 Way & Intermediate Switching of a Lighting Circuit 3 Plate Method Connections

Student training aid for the connections required to wire a lighting circuit using the 3 plate loop in method. Video explains the connection required within the ceiling rose, a consumer unit (fuse box) and in the 2 way and intermediate switches. The circuit is wired in twin and CPC cables (twin and earth cable) and is a wiring diagram for this circuit. This video will show learners how to connect up a ceiling rose and pendant and 2 way and intermediate light switches.

How to wire up a light and 2 two way switches and one intermediate switches. This wiring diagram will help you understand the connection requires in a 2 way and intermediate lighting circuit.

Link in the description for all the drawings you will need in this series of videos 🦾. I hope this message has been some help 👍.

I have watched many videos on two way switches with intermediate but never got clear understanding, this video with an excellent and easy to understand explanation made my day👌👍

[Cablesmith]

Good explanation gaz, I wish my college tutors would have been this clear 😀

[rusrus]

Without doubt the NO1 -Top tier of electrical training in the world!.. outstanding Video tuition !! Big thanks again.."Crem'e de le Mon't " As dell boy would say lol

[waltervolleamere]

Absolutely 1st class explanation you should be proud of your video. Walter from Liverpool Merseyside, retired electrician 😊

[georgedumitrescu]

Second to none as always. The best and most thorough explanation you will ever find. Easy to follow and also to apply in practice. What about a book which will have everything you teach in your college. I would call it “The Electrical Apprentice Knowledge”. Certainly it will be a must have for anyone serious about learning the electrical trade. Just a bit of food for thought. Well Done Gary.

Great video teacher. Many thanks for taking the time for doing it. 🤝

[jmohammad]

Fully qualified Electrician and I still watch these great back to basic video's from GSH to recap. Thanks Mr Gaz keep the learning tutorial rolling. Your teaching is much appreciated and simply the best.

[ukfreedivingbuddies]

great video, very helpful, thanks for uploading

[shaneporter]

You used the black conductor to connect the 2 commons, is this just a personal preference or can it be done with any of the colours. I was told not to use the black and it should be brown. Is there a kind of an unspoken rule where everyone uses the black. or does it really not matter at all? would really appreciate some feedback on this everyone as well. Thank you very much in advance.

[bdawinton]

wow a much cleaner way is by taking the live to the c running the two switching lines to each other and then take the other c to the bulb would add a picture if i could

[faithful]

What if they where no other option but to place intermediate switch at the end and not the middle

[pauljonseager]

Great video. I have a slightly different set up with my upstairs light in that the ceiling rose is wired to the intermediate switch (in the middle) and the 2 way switches are left and right (if it were a diagram) if that makes sense. Have you got any wiring diagrams for that set up at all?

[mohammadsarwar]

I've got a situation where the 3 core & earth is run from switch 1 to 2 and then finishes on 3.
The switch wire from the lighting loop is in the middle switch (switch 2)

I'm not sure if this will work as either ends of the 3 core are in switch 1 and 3.
Hope I explained it for you to follow.

Can anyone shed light on this!

[gkbailey]

Hi Gaz, love the videos, excellent reminders! Do you have a video that highlights the technique of running power to the switch?#

a fellow Gaz

Hello and thank you for your tutorial program
Would you please do a full circuit of heating system including solar?
🙏🏻🙏🏻🙏🏻

I understand that you have to identify the lines when there are different colour codes of cables in the system or using the blue as a switched line, but in a completely new installation (with the exception of using blue as switched line)? I mean the lines are identified by todays colour code: Brown, black and grey are lines.
Here in Germany in most cases it's not economical to install more than three switches that way. If more than three switches are required we use such a thing here in combination with retracting switches. Also available in a version for junction boxes, this one is for installation on a DIN rail:


You only require two wires at every switch, a line and a (temporary) switched line sending the short impulse to this central switch. So easy to extend later on and add further switches if required. I have installed one for the lighting in the staircase of my house. The price they state in the data sheet is on the high side, street price for this specific model is round about 30 Euros (27 GBP). To spare the contacts they switch at the zero point of the sine wave.

Can the switch line be at the intermediate switch?

[MLAL]

What do you do with the earth cable at the end, on a plastic switch?

[thattoolguy]

Great video as always Gaz, do they still teach the old singles method ? its a handy one for new lads doing conduit work
