Wiring Diagram Wired Through the Switch Lighting Circuit AM2 & AM2S - 2 Way & Intermediate Explained
HTML-код
- Опубликовано: 31 май 2024
- In this video we look a method of wiring 2 way and intermediate switching of a lighting circuit that is wired feed through the switch. Understanding this wiring diagram could be useful when undertaking your end point assessment for AM2, AM2S or AM2E. 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. This wiring diagram should help you visualise the method of wiring 2 way and intermediate switches when using wired through the 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.

Connections Explained - Wired Through the Switch 2 Way and Intermediate AM2, AM2S & AM2E Assessment

Sitting my AM2 today and they’ve asked for the neutrals to be at every switch, so this has come in super handy 👌🏼
Thanks for commenting and all the best with your AM2 👍🏻
In these wired through the switch videos, I personally would find it easier to follow, if you were to start by showing the CPC and the neutral connections continuing uninterrupted all the way to the light fitting.
With that out of the way, and the point made, I would then only have to follow and understand the paths of the line conductors.
I accept that in the site situation, you would be second fixing the individual switches and all the conductors, in the sequence shown.
This is not a criticism; it is born of interest, and I would welcome your response, please.
Thank you for your ongoing excellent videos.
This may help 👇🏻

Thanks Gaz
This is handy in landings of 3 story houses when you don't want 2 circuits in 1 box. The company I did my apprenticeship used this method in that scenario and it took ages to wrap my head around!
Video has come out at a perfect time, am2 is next week, very helpful thank you
I hope it helps.

It is surprising how many variants in wiring lighting there can be also the wiring method eg conduit (singles) or T & E. It is also surprising how many electricians don't know how to wire up intermediate switches.
Great video, can see the sense in a neutral at every switch point, very useful going forward.
Thanks 👍🏻
Top man..I was asking many electricians to tell me that I can use one of 3 core as N, no one knew this method....helpfull for staircase
Thank you very much 🤟🤟
Thanks for watching 👍🏻
as always your videos are always helpful, thankyou
Thanks Brian 👍🏻
Great video Gaz as always
Thanks 👍🏻
When I did City and Guilds 236 part 1 and 2 back in 1987/92 we were tort that on a two way switch circuit one switch should be in the off position and the other one in the on position.
@@Dog-whisperer7494 what was the reason for that?
Great video but one question could you use this same method with just a two way ? Feed to the first switch , triple between both switches and a twin and earth of the second switch to the down light , linking the neutral through grey on the triple ? Thanks 😊
Would it be possible to take the feed for the light from the intermediate switch?
If using T/E and want a neutral at every switch wire as a 3 plate system and drop a 3 core to every switch.
Leaving the circuit readily adaptable in the future!
Nice one
Thanks 👍🏻
Top man
Thanks
Hi. Don't know if you covered before in one of your 1000s of videos. I as an adult did my level 2/3 18th edition 2391 and going to joing napit soon. If I wanted to obtain my gold card how do I do this when all my work is domestic and I don't have any work that involves conduit etc etc... Im confused what you do ??? Thanks 👍
How things have change, from my time as a sparky, it was frowned upon to have neutrals in light switches, we used to run a 3 core and earth between the two two-way switches and then just a drop a twin and earth from the the ceiling rose down to the nearest switch. this meant we could run around loop all the lights then decied what was two way. this would be the feed and switchwire. No connectors etc required.
2 plate and 3 plate in all the year never hard this terminology. But I would like 3 plate of chips. Done all the methods for lighting from a socket yes with a fused spur. Have only had to but in a 3 way one time did work 1st time had diagram on scrap of card.
@GSHElectrical is there a reason you have the line conductors reversed in your L1 L2 at each end of the two way?
Because it doesn’t matter 👍🏻
do you get given the wiring diagrams to use in the AM2 exam!??
Silly question, when sleeving the black with brown sleeving would It be okay to sleeve it all or do you need to see it’s the back and use a small bit of brown sleeving?
small bit of sleeving is fine
great video but i have one question how come you dont put the strappers from L1 to L1 and L2 to L2 from the two way switch to the intermediate switch?
Thought the exact same
This is the exact same method as if you were using single-core cables, but instead of the neutral going straight to the light from the consumer unit, it has to follow the rest of the cables due to them being all together
It's two way switching always done this way in Britain? We never do it that way in Ireland, we bring a feed to one common, a switch wire to the second common and a pair of strappers between
No, your way is the standard and has been for decades. This way is what generally is taught now for a couple of reasons so there's a neutral at every switch location as more and more smart switches are coming into the market, but mainly it's for saving cable and allowing for future alterations.
Do you get these wiring diagrams for am2 on the day? I've got mine at the end of the month
You may see them on them day but quite possibly have to wire the circuit from memory - worth understanding before the big day.
Can I run the neutraral true the lights instead of switches ?
Not on AM2 or AM2 S
@@GSHElectrical Thank you
I have done 10 months Diploma course from india, and I have experience as electrician about 7 years. I don't know how to get Gold card here in the UK.
Great video but i see a misleading fault that when you study the switch arrangement you have what would be L1 going to L2from first switch to last , should this not be L1 to L1 and L2 to L2, sorry
I'm curious - in what scenario would this lighting circuit ever be used?
AM2 assessment 👍🏻
@@GSHElectrical Many thanks for the reply. Sorry, I should have been clearer: I meant, what real-life scenario would the lights be connected to the last switch?
🙌👏👏👏👏👏👏🙏
Hold on so I’m your AM2s you get wiring diagrams? Do mine on Monday
Interesting. It would illegal in my country as changing colours of wires with oversleeving is not permitted here.
You probably use conduit then, that way you can choose your colors appropriately in the first place. When you use cables, you kind of have to, unless you burden the entire industry with manufacturing every kind of color combination that might be necessary.
@@JasperJanssen We use cables. But three core is made in three versions with different colours. Brown Black Gray, Brown Blue Y/G and sometimes I can buy Brown Black Blue but it is very rare. But if the regs needed neutral and cpc in every box i would just go for 5 core cable. With three phase colours , N and CPC.
@@evzenhedvabny6259 yes, but when you use two of the lives for strappers and one as either the switched or unswitched live, you’re still changing the meaning of conductors - just not as radically as N to Lx or let alone earth to anything else.
(Personally, I’m in favor of making N and E not able to be used as any variant of line or vice versa, mind you, just based on a ‘principle of least surprise’. Fucking up which way round you hook up your various forms of line and switched line is not nearly as problematic as getting the neutral or earth wrong.)
@@JasperJanssen Not at all.Brown Black and Gray are live colours over here. Earth has to be earth only no other use permitted. Regs were changed about 10 years ago . They allowed Blue as live in some special cases where confusion is not possible(I have seen it only in some motor drivers from Germany). Usually i use brown wire for common at the 2way switch Gray and Black as strappers. British way of 2way switching is something unknown here :) Feed to L1 light from L2 COM connected :) Some people here do not believe that it works. I worked as electricians mate in England for two years. I do not understand their obsession with oversleeving. I love teir obseession with SWA. Love their conduit system, hate their metal backboxes and have ablsolutely no idea why tey do not have SWA with single phase colours Brown Blue Yellow/Green.
@@evzenhedvabny6259 We do have 3 core swa (brown, blue , yellow + green) and our line conductors are brown, black, grey and blue but we sleeve the black and grey so it's all identified as a single phase line conductor. If it were 3 phase, then no sleeving would be needed as the colours would be correct.
Strippers should really be wired L1 to L1 so that when all switches are up the light is off. But I dont suppose that's marked on with AM2
So if both switches are up then some one goes to one switch and turns the light on, you then have one up one down, then if someone goes to the other switch and knocks the light off. Both switches would be down and the light would be off. In other words pointless.
@@solidus784 When I did City and Guilds 236 part 1 and 2 back in 1987/92 we were tort that on a two way switch circuit one switch should be in the off position and the other one in the on position.
@@Dog-whisperer7494 what about the intermediate switch or more intermediate switches installed? 😳
@@m101ist intermediate switches between the two way are just that , example corridor two way switch at each end and say two intermediate in the middle one two way at one end is in the off position one intermediate in the on position second intermediate in the off position then the two way at the other end in the on position,
So , you have on of on of , doesn’t matter we’re you start you can play with it all day and you will always have on of on of . Draw it out and see , if I am wrong feel free to correct me 👍
Black shouldn't be used as a neatral as it could be confused with older wiring colours.
Thanks for taking the time to comment 🦾👍
If you correctly identify the black as a neutral using blue tape or sleeving then it is acceptable but grey is preferred by many electricians
When we had the change in colours it was known as deneutralising the black I think it came from the lighting federation. we are using the gray conductor which would have been the blue in 3 core and CPC.
@@peanutpotion black was the old wireing for neutral.
I don't think he mentions this in the video, but he used the grey as his neutral.
Can you add another switch to this
Yes - as many intermediate switches as you want 👍🏻
Do I convert the last switch to a intermediate switch and then add another?
@@GSHElectrical Can one convert, wire a intermediate switch for a two way switch?
Excellent video again.
But, Help.!
Please clarify, why on the 2 plate WIRED THROUGH THE SWITCH system, with only 2 switches, it was NOT necessary to continue the Neutral through to the 2ND / FINAL switch to supply the lighting point.
This seems to be a different understanding of what is required and what is correct.
Having only seen this ONCE in my many decades of working in the industry, when a Commercial Electrician tried to do a PVC/PVC house rewire on the 2 way switching.
Commercial and Domestic lighting circuits are done in totally different ways.
WIRED THROUGH THE SWITCH method, seems to be a mixture of 2 methods of wiring. Not helpful at all.
Plus, having ALL the connections in one position always helps in future alterations / additions and fault finding in a Domestic installation.
Black conductor as the Neutral..... What is all that about.? Who is writing this stuff.....!
This is the wiring method required by NET services when learners are doing AM2 or AM2S or AM2E. 👍🏻
@@GSHElectrical Is it ok to use the black conductor as the neutral, or is there a reason that the grey is used instead? Thanks Jez
@@GSHElectrical If one's using the black or grey wires for neutral could one use a blue sleeving to identify that is the neutral wire. ?
I have just view the video,as answer my question, thanks.
@@GSHElectrical Should have a 3 core wire, twin browns, one blue and CPC for the strappers for this wireing configuration.
Alexa, turn on light.
🤣
No I'am having a break.
