Wiring Diagram 2 Plate Method - Taking the Feed to Another Room and Switch Connections Explained

[@hilalkhan302]

The best tutor in the world much respect from deep my heart ❤

[@GSHElectrical]

Much appreciated 🦾

[@BobBenz55]

I normally use junction boxes and feed each room from there, much easier and a less crowded box. Nice video 👍🏼

[@kbagheri9026]

Me too, I was qualified in Denmark, I have no idea about your expressions, 2 plate, 3 plate etc. but JB is what I always use.

Great video, very well explained,thanks a lot.

Could you do a video on the real world scenario of hall landing light switches, using the two plate method, highlighting the issues of two consumer unit circuits providing the feeds and not sharing neutrals. Probably good advice to make these the end points of the the radials when possible to reduce the cable count. I don't think I have seen this covered anywhere and it seems to cause a lot of problems and confusion.

[@danielteyehuago1633]

Wow! This is very informative, thanks for sharing it with us. It worth it and the best tutorial on the topic for me...wtc

[@GSHElectrical]

Thanks 👍🏻

[@Dog-whisperer7494]

Fantastic video Gaz as always. Personally I don’t like the idea of having two or more cables of one switch unless it is for two way switching. And I don’t like the two plate method , I would take the feed to a wago joint box then on to were it needs to go. But we all have our own way of doing things. so each to there own. Fantastic video any way Gaz 👍❤️⚡️

[@alerighi]

These days with the popularity of smart switch devices like Sonoff having the neutral at the switch makes easier to install them possibly in the future. Yes in theory you can install them at the light position, but it's more difficult and they are less accessible in case you need to do something with them.

[@sward86]

Is it possible to get a neutral to the second switch to feed another room as well?

[@P-lc6sc]

I would like to add an entirely new switch and light to a two plate circuit. The switch at the start of the chain is on the first floor and is very full and will not take another connection. It is a two way switch with 4 x 1.5mms in it. Identical to your drawing at 8:30 My query is, Can I split the wire that is feeding the next room at a junction box to create a new light and switch. So instead of daisy changing at the end of the entire circuit, I split into two before the second room? the daisy chain will then continue as installed but now with my individual light spur and switch additionally?

[@johnfieldhouse2157]

Great video but still a bit confused. If I wanted to use the 2 plate method on a 2 gang light switch supplying two different sets of lights in the same room how would you do that? Would you, for example simply run a brown cable from common to common instead of heading off to the next room?

[@GSHElectrical]

Yes 👍🏻

[@johnfieldhouse2157]

Thank you so much! Great videos.

[@leeedwards3783]

Good call. My 3 gang switch has 4 wires all into the common wire. This must be the opposite of linking the commons. Think linking them is the better option

[@raj080288]

Nice work Gaz! When the connection goes off to the next room, does those wires connect to the switch or the lights? Thanks

[@GSHElectrical]

The feed would come from the switch to another room if the 2 plate method was used 👍🏻

A lighting circuit is a _radial_ circuit. In short you _daisy chain_ from one light to the next. So the lighting equipment needs to be a *junction* to take the lighting circuit to the next light. A light has two parts: *1)* the light fitting to the lamp itself; *2)* The switch. *a) Light fitting as a junction:* In a two floor house with an attic, the light fitting tends to be used as the junction to daisy chain the lighting circuit to the next light in the circuit. Then a wire to the light switch. So, a circuit is a wire from the CU to each light fitting with each having a cable to its own switch. *No neutral wire is at the switch.* *b) Switch as a junction:* The way to do it in flats as there are no suspended floors or atttics, is to daisy chain the lighting circuit to the switches, then one wire to the light fitting. The opposite of *a)* above. So, a circuit is a wire from the CU to each switch with each switch having a cable to its own light fitting. *A neutral wire is at the switch.* In *b)* above, the daisy chained neutral needs a junction terminal on the switch or behind the switch in the box. Hager and Schneider provide a switch with an N terminal on rear of the switch, so the switch is the junction. To my knowledge Hager has been making one for at least 10 years. If the switch has no N terminals, Wagos or terminal blocks have to be used inside the light switch box. In *a)* above there are problems of wiring colours when a cable is taken to a switch, as cable with the L (brown) and N (blue) are used, needing a coloured sleeve over the N wire. There is special wire available with a yellow conductor for this, but it is rarely used. Using the switches as a junction solves this. As lighting is now more varied with downlighters, wall lighters, etc, taking the lighting circuit daisy chained to the switches makes more sense - multiple downlighters can easily be extended. It is also easier to fault find. It means the boxes behind light switches have to be far deeper to accommodate more cables and Wagos to form the junction terminals. If a lighting intermediate switch is being used, taking the circuit daisy chained via the switch makes it easy to fit one. That is how I tend explain it.

[@johnburns4017]

@@danielwake7621 There is nothing wrong with doing that.

[@tombright2349]

To add to the chain, do you need to find the last switch in the existing chain or can you essentially spur off any switch in the chain? I am assuming you need to work from the end of the chain?

[@GSHElectrical]

No you can come off any light to add another that will come on at the same time 👍🏻

[@tombright2349]

@@GSHElectrical thank you and Merry Christmas ... Great tutorials

[@tombright2349]

@@GSHElectrical sorry just to clarify, if it's a brand new/additional light ... you can simply spur off the nearest switch? (The light will work independently of the switch being spurred off)

[@leebond1837]

Do you often find two plate method with ceiling roses? Or just down lights?

[@GSHElectrical]

Loads of times now in new builds

[@scoobydo2]

Is it OK to run 1.0mm from course to switch, then to led lights. Use to be 1.5mm?

[@sward86]

Is it possible to get a neutral to the second switch to feed another room as well? Is it acceptable to tap of a neutral from the light fitting as its on the same circuit rather than running a second T&E along with 3C&E?

[@m101ist]

So in the 2 plate method, 1gang light switch you have 3 twin and earth cables going into the light switch ?

[@GSHElectrical]

No that sounds like the 3 plate method… loads of content on the channel that could help

[@m101ist]

@GSHElectrical The 2 plate method, are there 3 cables going to the one gang light switch. One permanent line feed to light switch, one switching line feed to the lamp holder and one permanent line feed cable to the next room from the light switch. Have I misread somewhere along the line. Please correct me if this is the case.

[@kbagheri9026]

GSH Electrical, why not use a JB and supply from there? What is the advantage with this method??

[@LawrenceTimme]

My 2 gang light are all wired with a 4 wire cable with no cpc. Is this bad? Im trying to replace all of them.

[@GSHElectrical]

If you have no cpcs then don’t use metal switches

[@holmesjunction]

I presume extending a 2 plate system in a 'lived in' house is strongly recommended by decorators, unless you like surface trunking?

[@isaacjohnson1734]

What if its run in pvc singles and there is no neutral at the switch only at the ceiling rose, I have seen them in council houses, very annoying?, can you do a video on this please

[@olly7673]

GAZ, your presentation is excellent and I think you should think about teaching electricals as a profession, as your very good. Kidding, I've been a big fan of your channel for years and have been helped in a lot of subjects and glad you are still putting these out. One question with regards to all the connectors in the back of the patress/ knockout box. What's your thoughts on floating cables behind the switch? I can't see an issue but there's some discussion that connectors floating around is bad and they should be secured within the enclosure.

[@GSHElectrical]

Thanks for the great comment - I don’t mind a Wago in the back of a box but if you could secure them then I would 👍🏻. Have a great day. Gaz

[@stupidlogic2987]

@@GSHElectrical A roll of Tower (other brands available...) two sided tape normally used for fixing trunking would do the trick to fix the Wago.

How to split one light if it's wired in swith feed method I mean if three lights are connected to one switch and permanent live in switch how I can put another switch to turn on light from another room

[@tonyweavers4292]

Would it be bad practice to mix 2 plate method and 3 plate method?

[@GSHElectrical]

Yep not a problem - my house has both methods in it 👍🏻

[@arontoms3085]

@@GSHElectrical That's good to hear, especially as the introduction of smart light switches such as the SONOFF means the 2 plate method is advantageous as the Neutral is at the switch as required by smart switches. If it's possible to mix both 2 plate and 3 plate method, rooms can just be moved to the 2 plate method as and when a smart switch is added to that room whilst leaving the existing rooms as 3 plate.

[@Nicolae-r3t]

Why not use com as live but use L2?

[@jonw2570]

When installing a lighting circuit with say 3 gangs for different lights.. all fed at switch and linked across, could you run a 3 core to one light if its accessible above and taking a permanent live also to future proof it so you have perm and neutral at light to take from

[@jonw2570]

Thinking this will avoid chasing out wall to take another wire to another light but also by using a 3 core + cpc instead of 2 core + cpc you only add 1 core to an already cramped switch instead of 3

[@nigellewis804]

Why not use dp light switches

[@alunroberts1439]

Who came up with that bright idea 🤣🤣

[@davycrocket9158]

Plate, aren’t they things you find in a dining room ? And who decided that it was a good idea to start calling an earthing cable a CPC , probably the same moron who changed live red to brown.

[@stupidlogic2987]

It's a cottage industry so they can charge you for re-certification.

[@davidclarke2513]

So you have to get the permanent line from your switch which is chopped into the walland cannot be git at without cutting a chase to get to the permanent line cable whereas before you could find a permanent line connection from any light in any room ,so as an Industrial sparks of 50 years whoever came up with this crazy idea baffles me,you even have to put the neutral cables at the switch into connectors thus making more connections in your circuit therefore there being more of a chance of connections coming loose,yet you are pushing this method which makes me lose my respect for your teaching

[@erelpc]

It's in the syllabus, mate. They're not pushing anything, you have to know both ways. The 'old' (3 plate method) you mentioned isn't old, it's still being used, along with this 2 plate method which is often found in commercial buildings which give easier access to the switch box.
