- In this video we look a method of wiring 2 way and intermediate switching of a lighting circuit when wired through the switch. Understanding this wiring could be useful when undertaking your end point assessment for AM2, AM2S or AM2E for apprentice electricians. In this system the neutral is taken through each of the switches meaning at all 3 switches you will have a connection for the neutral in the back box. This wiring should help you visualise the method of wiring 2 way and intermediate switches when using wired through the switch. I make off all the connections using feed through the switch method of wiring 2 way and intermediate switching. Care must be take to identify your conductors correctly in your switches and connect the neutral so it passes through each switch.
In your end point assessment you may NOT have access to the lighting wiring diagram once your assessment starts but you could be expected to wire it or draw it from memory.

Your explanation, your diagrams are absolutely fool proof.
As a teacher or lecturer you are amazing and I want to say thank you for your detailed videos.
I've done some amazing projects using your videos.
Thank you again
Currently going for my 2391-52 and AM2 assesment and your videos are priceless, great work 👏👍🏻
Massive thanks and all the best with your exams 👍🏻
@@GSHElectrical Please I want to buy the cable strapper tool you are using... Can you she the link with me
Took me a few weeks to get my head around inter switching and watch this and it’s just clicked thanks great video 👍
I really like this method of 2 way / intermediate switch wiring as you always have the neutral at the switching point so you could tap off it at a later date for extra lighting or when fitting a smart switch. Took me a couple mins to wrap my head around it but it’s pretty much the same as single and earth being the permanent line from the board at one end and switched at the other to the lamp with the twin strappers in between. Very good!!
Thanks for commenting and watching 👍🏻
I remember seeing a similar thing like this in the old wiring colours. Red from supply was in common as with switch line on opposite switch. The black from both twins were connected to the blue of 3 core L1 and L2 were red and yellow respectively yellow. Whenever I watch your videos brings back memories of my college years of 95 to 97
Great simple and very easy to digest. Keep doing what you do best. Brilliantly presented Gaz 👍.
Thanks Ray 👍🏻
Great video and very clear. Thanks a lot!
Thanks Clive for commenting and watching 👍🏻
Brilliant video, love the format 👍
Thanks 👍🏻
Great video! Learnt alot. I did the same recently on a rewire!
Thanks for commenting 👍🏻
We call this set-up in the US, a three and four way connection. The wire colors will definitely throw off an electrician not familiar with it. Nice presentation!!
In the US they call this 3 way switching and in the U.K. 2 way and intermediate switching. Massive thanks for commenting and watching 👍🏻 Gaz
Great video as always buddy
Thanks Andrew 👍🏻
Exactly what I needed nice inr
Thank you so much GSH team.
Thanks for commenting and watching
Love you videos...most are common sense if you've been trained correctly...but your presentation is brilliant thanks 👏👏
Thanks for watching and the kind words. Gaz
Helpful as always
Thanks Carl 👍🏻
Yeah the colour change was a mine field dangerous.. I alway had a way of remembering the grey as a neutral conductor by in my mind saying gray is a neutral colour still do lol thanks gaz👍
Thanks for your input and watching👍🏻. Gaz
You are a great teacher, thank you.
Thanks for commenting and watching 👍🏻
Fantastic video.
Cheers 👍👍🥰🥂
Thanks for commenting and watching 👍🏻
Thank you very much🙏 very clear video.
Thanks for the support 👍🏻
Gr8 vid as always
Massive thanks 👍🏻
More please great video
Thanks for the support 👍🏻
As always Gary the best🙏
Thanks 👍🏻
Much appreciated.
Not a problem 👍🏻
Great thank you ☺️
You have a way with words!
I love your’s blogs sir Thanks you.
👍🏻
Salute for this video is good
Thank You 🙏
No problem 👍🏻
Can I ask what the advantage is of wiring through the switch with bulb on end of 2 way / intermediate rather than on first switch? Thanks
Another great video! I just wish that all the world would follow 1 wire color scheme.... it would be so much easier....
Wouldn’t it John 👍🏻
If that’s in the Am2 could you just use the long lead method for r1+r2 and test between cu and earth at the light to get the overall R2 as it’s the furthest point and test between live at the board to live at the light as it’s the furthest point and operate the switches and the highest will be my R1 so I would just add them up to have overall R1+R2 for the circuit?? Thanks
Thank you for sharing your knowledge
That has helped a lot
Next question sir
That’s was 2 way and intermediate
To one light fitting
How would it work for 2 /3
light fittings
Ie
Switch at the Bottom of the stairs
To make bottom light middle floor light and attic floor lights come on then to be able to switch them all on and off from each floor
Thank you
Also I came across the normal 2 way method without neutral. I found the yellow and blue as strappers and red in common from 1 switch. On the other switch I found the red from twin and earth in common from 3 core yellow and blue as strappers and the red of the 3 core was connected on the black of twin and earth with connector. All colours were marked with red sleeves. Some I've seen black was in common and reds connected on a connector block. Is that still
Thank you for the free download. 👍🏼 👌
I watch your videos everyday. Great teacher.
I have always used the grey as a neutral. As blue (old colours) became grey. In SWA ive seen lots of sparks use the black as a neutral !!!.
👍🏻
Thanks very much great informative video. This is all new to me using the grey as carrying the neutral on through so i really enjoyed learning about that. Am i right in saying that in the 3 plate method theres no neutral at all at the switch and they are all line connectors either switching line and 1 perm at the first switch and the role of the 3 core is to carry the common on through to the final switch not mattering if theres 1 or 10 intermediate switches in between and that the other 2 conductors of the 3 core cable link up the L1 and L2 to the intermediate and last two way switch and theres no neutral whatsoever because its at the 3 plate in the ceiling so this is only for 2 plate because the neutral is at the first switch and its not needed at the intermediate and final 2 way switch but its vitally important at the light fitting and this is why its carried through to here. Does that make any sense at all Gaz lol.
This should help

Hi, re the Wired Through the Switch 2 Way and Intermediate video. In my wall switch, I have 3 wires. 1) brown wire going to common, 2) grey wire with brown sleeve going to L2 and 3) black wire with brown sleeve going to L3. Please can you help me understand how this configuration wires into a smart switch?
Thank you
Could you do a video on
2 way and intermediate
With 2 light fittings
As you may have on top of landing and the bottom of the stairs
Thank yoi

Can you have the cable that goes to the light from the intermediate switch or does it have to be from 1 of the 2 ways??
Has to come from the end 2 way switch 👍🏻
Please I want to buy the cable strapper tool you are using... Can you she the link with me
Good
Thanks
Are u doing a 3way switch so those right eliminates having to run travlers from switch 2 switch!! Just a wo during cus I never heard of a 2away switch just 3 or 4 but that's cool if that's what it is
This is the wiring method for AM2 and AM2S for 2 way and intermediate switching of a lighting point. 👍🏻. Gaz
My two pennies worth., When they change the wiring code , they fixed a problem that didn't need fixing. When I go to a installation has mixed wiring codes , I'm extremely cautious, is the black a neutral or is it a live . To be honest it a problem we are going not have for many years to come
Great point 👍🏻
When I was an apprentice I was taught not to wire this way basically the feed one end and the sw the other as you would do in singles years later I noticed in an on site guide think it the yellow one telling you not to do it as it interferes with induction loops Has this changed
This is the wiring method required for an AM2 or AM2S assessment 👍🏻
The whole reason I never bothered to attempt AM2. Lighting is a complete ball ache for me and even after years I still don't get it and shy away from it.
Just wondering why we sleeve black with brown when black is a phase colour anyway?? Obvious makes sense to identify neutral and earth if black is used for earth but why sleeve black as brown??
I was on a job about 6 months ago and the installation was about 3 years old. Wired by a so called professional On the smoke alarms the black was used as the neutral. 99 % of the time amateurs use the black as the neutral . What a crazy world we live in changing to old colours that almost everyone could make sense of
old boys love it
If, in wired through switch, the feed to the light goes to the first switch where we have our permanent live, how will we wire the intermediate or the last of two way switch?
@Troy Mclore brilliant. Many thanks. I need to make a diagram of it now.
@Troy Mclore what if tye permanent live goes into common and we use twin & earth for the L1 & L2?
@Troy Mclore with no intermediate switch. I dont need to connect brown in the commons. I can use twin & earth in L1 & L2. Can I?
@Troy Mclore thanks for your reply Sir. I'm not working as electrician though i did my city&guild and 17th addition long ago. My electrician (from China) rewired my house and he wired through the switches for lights. We used to do the loop in method in the ceiling. Wired through the switches was not very common in my work when i did some work as an electrician.
So for my understanding when wiring through the switch, permanent live goes into L1, the switch live (load) goes into L2 and from three core cable for second two way switch brown goes into commons black (with brown sleeve) goes into L1 of the first and second switch and grey goes into L2 of both switches where there is no intermediate switch. Neutral of load is connected to the feed in neutral ( which comes with permanent live as twin and earth).
the colour change never bothered me as it changed during my apprentaship
I asked a question on my last job as to why we had wired feeds to lighting position instead of the switch knowing JB would now have to be used everywhere and was given the strangest look from the foreman and simple told "you dont wire neutrals down to switch". I wanted to say I'd seen it done many times before so what was his reasoning but the look he gave told me not to bother asking.can you clear this up at all?
Was it wired in singles or T+E? if it was singles then that will be why you dont take it down to switch
@@JaackBorland it was twin and earth wiring using 501 junction boxes everywhere
@@drpantastic1969 ah even still there isn’t a need for neutral at the switch using jb method, it can be taken to switch but for ease of wiring it’s taken straight from jb
I thought for ease of wiring it's better to have feeds at switches(neutrals connected in a block) then you would only have maximum of 2 cables at at lighting points eliminating need for j.bs .is there a regulation on this or is it just choice? I'm sure I ve seen a switch with an unswitched neutral terminal built in like a connector block to accommodate this style of wiring
@@JaackBorland I threw another question your way if you know the answer and have time to answer it.thanks for the previous response
What is the need for a neutral at a switch
The need to Pass-Thru (in this case).😅
The way I think of the new colours when deciding what core to use for CPC, Line and Neutral:
Red (line) = Brown = L1
Yellow (Earth) = Black = L2
Blue (neutral) = Grey = L3
In old colours, when using 3 core for single phase, yellow would be Earth to match green and yellow. Blue would be neutral to match the blue in flex (which was brown and blue long before the harmonised colours came into force). Therefore, sticking with that principle, the yellow is now black, therefore black is Earth. Blue is now grey, therefore grey is neutral. Sorted.
It is strange though that things like the Klik stuff etc use the black as permanent live and brown for switched. I know it doesn’t matter as long
would get confusing using a black as a switch on a 3 pin klik though and visa versa for the 4 core
Why are you saying you can't go on the same side?
Hi gaz I’ve completed my level 2 2365electrical at college and my level 3 8202 I’ve got an apprenticeship opportunity will I be retaking those courses or would I start ahead of it as I only need my nvq - am2 and gold card
I don’t understand how the permanent live continues to each switch
This should help 👍🏻

Why ???? Taking neutrals through a switch very dangerous
Why would it be?🤔
Thought this was a porn channel!!
still no idea - someone teaching yet doesnt know how to teach !
Mate you are amazing thank you for these clear instructions, just amazing thank you
