Link in the description for all the drawings you will need in this series of videos 🦾. I hope this message has been some help 👍.
Hello
I can't find the link for the drawings can you help
If you come straight from the distribution board to a JB, is there a max number of rooms/lights you can supply from that?
Thank You for Your Diagrams and Explanation of this Electrical System! Your tuition made it possible for me to complete an installation of light switch, two batten lights and two double sockets in in a safe and Professional Manner! Thank You, Graham.
Ffs!!! Finally a diagram I understand, excellent guide. Will be doing this soon. Thanks 👍🏼 and amazingly explained👌start my courses next year 👌
Thanks for the great feedback 👍🏻
What a "teacher", my understanding of mains electrics has increased dramatically !! Many thanks again.
Thanks for watching and taking the time to comment 👍🏻
This is outstanding. I bought an LED downlight and the instructions had one line about connecting color to color, and nothing about how to connect it to a wall switch/dimmer or how to control multiple LED downlight lights with a single switch/dimmer. This video was excellent. Thank you.
Thanks again. Clear explanation - a picture is worth a thousand words and it's a good idea laying real cable on top of the drawing to make your point.
Thanks
Yes the videos on GSH are all practical. Big tip to you to watch them all.
The diagrams and matching practical demonstrations on this channel are simply superb. The pace of the videos along with the great tutoring style make the whole learning process enjoyable - what more could you ask for - many thanks.
Hi Gaz, thx for sharing this pdf file.
The level of knowledge you show here on the channel is at least equivalent to the level of electrical inspectors here on the other side of the pond.
Thanks for the kind words, commenting and watching. Gaz 👍
Hi Gaz, thank you for making this nice video, showing how to wire a joint box the proper way. In my opinion the most important part of this video is that you dress the conductor the longest route to the contact, so in case of reconnecting you have enough length to strip the conductor (with a knife), double over and put it back in. Your enthusiasm ensures that we keep watching. Greets from the other side of the pond XD. 😍
Thank you sir. This was the most informative breakdown I've seen. It helped me figure out my recessed light/switch/outlet wiring wasn't working. The light was always hot, but your breakdown solved that. Thanks a ton!
And thanks for the great comment and feedback 👍🏻
Very easy and simple explanation thank you GSH electrical
Thanks 👍
Brilliant explanation Gaz. I have been doing a lot of this lately with Doctor Electric 👍🏻
Thanks for the support Adam 👍🦾
@@GSHElectrical my pleasure Gaz. Brilliant content 👍🏻
Great descriptive/clear video. Thanks
Thanks for the kind words John 👍🏻
Thanks for sharing this video, simple but not many videos out there showing a connection to down lights as most show ceiling rose
Thanks 👍
Great as usual sir.. Many thanks 🙏
Thanks
Thanks for watching
This was perfect thank you
Thanks 👍🏻
Thanks Gaz brilliant video again very clear.👍
Thanks 👍
The videos are great, thank you
Thanks for a very interesting video. You have a very good style of explaining with intricate details that really makes it so easy and as a matter of fact even fun to learn. Thank you 😊
Thanks for the great commenting 👍🏻
Wow! This is very informative, thanks for sharing it with us. It worth it...wtc
Thanks for commenting and watching 👍🏻
Brill explaination
Very good explanation. 👍
Thanks 👍🏻
Excellent presentation as usual. So am i right in saying that this is another way you could wire up maybe a series of downlights and also this would keep the no of cables at the switch workable as oppossed to the 2 plate method where you take the feed to the switch. Thankyou for showing another method as i thought you were limited to 2 and 3 plate cheers from an old man trying his best to learn and practise a fascinating trade. You are a legend Sir.
Wow thanks 🙏 this helps me so much 👍you are perfect
Thanks for the kind words 👍🏻
The lesson is great
Thanks
Exactly what I was looking for,clear and precise,thank you very much.
Thanks Jean 👍🏻
Nice one gaz 👍
Thanks 🦾👍
See loads of stuff like this in older houses but none of it is earthed just 2 core red and black cable. How do you go about earthing the system would I have to re wire the full lot? Mint video
Are the accessories plastic on the lighting circuit..?
Thanks for the video. I have to put 2 strip lights into a loft; the lights are on each side of the loft and the switch and junction box are in the middle. Could i run a cable from the junction box for each light so that they come on together raither than having to daisy chain/ radial from the box to a like then back past the box to the other light? thanks : )
Hi Gaz, I’m learning so much from your videos but I would rather get an experts advice. I currently have 1 pendant, 1 switch feeding to a mini consumer unit in my garage however I was wanting to upgrade or replace the circuit to run 2 main pendants and a separate pendant (basically 1 to use most of the time then when working at the bench have the extra 2 lights). I have 2 doors into the garage and would like to be able to switch either or both on from either door. I hope I have explained this but if you could draw a diagram that I could follow I would enjoy the challenge.
Many Thanks
Jonny
Does the live and neutral go back to the consumer unit to form a ring circuit, as with the socket ring main?
Wot would be the diagram be for this but with two 2 gang 2 way switches?
To control 5 down lighters...
(2 on one side of a king post truss and 3 on the other side of it ) from two
2 gang 2 way switches on opposite sides of the room...
All from a central JB source in from the rose below the loft ..?
Would be very grateful for any help in this matter...
Keep up the good work
Cheers Chris 👍🙏🇬🇧
Great videos, really clear. I watched the two plate method video with neutral running to switch, is there a video where you have run neutral to switches in a 3 way lighting circuit please?
Also a cheeky request, can you offer guidance on installing downlighters in a vaulted ceiling, not sure what to do to avoid compromising the insulation and vapour layer (by making a hole)

@@GSHElectrical thanks, will look at those. Any thoughts on vaulted ceiling downlighter question please?
@@jontrawford8233 Bit late now I suspect, but you ar right to worry about where the airtightness and/or vapour control layers are going. Downlighters are a problem here. Pro-clima kaflex grommets are a great way to put a cable though a membrane: www.greenbuildingstore.co.uk/product/kaflex/
But it depends on the construction whether you have space to put a downlighter in the plasterboard but keep the membrane intact above and just put the wire through that. You might need a taped-in box like the optime (www.ecologicalbuildingsystems.com/post/optime-airtight-downlight-protectors-passive-house-insulation-series-part-11) which is very difficult to seal in if it wasn't done when the ceiling was built. You'd have to cut out a bigger bit of plasterboard: sort out the wiring and membrane behind, then repair the plasterboard hole.
So am i right in saying the reason why the newer style is called a "Maintenance free" junction box is down to the fact it has means of cable retention therefore no stress on the connections will be applied from pulling cables around on the roof etc loosening the terminations?
👊🦾
Love your videos, and I don’t mean to be pedantic, but millimetres squared is not the same as square millimetres.
That would make a 10mm ‘squared’ cable 100 square mm in cross-sectional area, unless I’m wrong. Which I could be 😁
Great video. Is your series not numbered? Battling to follow in a good sequence

The playlist is in a logical order 👍🏻
So as a total non-electrical person, if you had say 7 other rooms each with separate light and separate switches, do they all take a live from the first connection box if they are on the same circuit on the consumer board to the next connection box. So you have a connection/joint box in each room? On separate note, I would like to highlight a potential electrical hazard. Historically, when using an apple computer charger, the cable becomes slightly split at the plug ended into the computer. To ensure this doesn't happen I had wrapped some electrical tape around the cable and the plug shroud. Then after about 4months I took the tape off and found that the electrical tape had caused the rubber cable to literally dissolve and exposing the cables. Not sure if theses normal, or if it was dodgy electrical tape. However I believe the electrical tape was purchased at B&Q, so it was from a reputable source and should therefore be certified for its intended use. Whats your thoughts?
This and other videos in my playlist call taking the feed (supply) to the switch will help.

Hi, running the lives neutrals and cpcs from each room back to the first connection box is possible but then that first box will have to be a rather large example that will be very busy. It makes more sense and usually is more economic in cable length to just string from one to the next and so on.
Wiring conductors are insulated with PVC, which can be flagged with different coloured electrical tape as is done in this video to use the blue wire as a black switched live wire. Cords of plug-in devices can be insulated with pretty much any insulating material, which is not necessarily compatible with the glue of electrical tape.
Instead of using standard junction boxes can wago boxes be used
100% 👍🏻
For a busy father of 3 considering a career change to what he should have done in the first place... Ie being an electrician, what would you suggest the best route in would be? Ideally I'd like to become certified for domestic electric work, including installing EV chargers. Cheers :-)

Can I use a wago junction box in place of the old style junction box?
Yes and that was stated in the video 👍🏻
@@GSHElectrical damn I must of missed that bit! But thank you for the reply 👍👍👍
Thanku sir what u teach us bebless more but i ask question plz tell us that we use which cable mm and from consumer unit how many Amper or watt thanks a lot
1mm2 or 1.5mm2 and a 6amp MCB
@@GSHElectrical bebless i have seen
Isn’t this also called the looped method?
Level 3 hint
10ma rule
Look it up in the blue book
I called it a junction box, they also black or brown if I can remember. 😳
👍🏻
By the way you can by and in fact you should buy a brawn to Brawn cable not blue
And you have to pic a sleeve otherwise in both end
In lesson we use brown and brown but lots of colleges in the U.K. don’t use this cable so for these videos I used brown and blue - I left Tresham college back in April 2020... I am continuing these videos as I miss teaching and my learners so much. All the best. Gaz 🦾👍
My loft is a mess cables just chucked down don’t people take any pride in there work why can’t they run abit of 2 inch tray to keep all neat
Loft wiring being a total mess is absolutely standard. To be fair it takes significantly more time to do it neatly. That costs money if paying an electrician (and DIY is strongly discouraged in the UK these days).
If you don't know how to do this without a RUclips video, you have no business doing this in the first place IMO.
Everyone has to learn sometime. And this has useful details like looping the wire in the JB for later changes and marking the switched live with brown sheathing which is the stuff that isn't obvious if you just work it out from first principles like I did many years ago.
Thanks
👍
