LIGHTING CIRCUIT FAULTS. Some common problems with lighting circuits and solutions.

- There are many occasions when a customer has problems with lighting circuits, but there is little to go wrong with lighting, the occasional lamp that blows, maybe the odd switch that decides to stop switching and that is about it.
A lot of problems are self-inflicted though, usually after a decorating or renovation spree. The customer decides to change the ceiling rose and then realises that there are 10 wires to go back into the new rose. Or they will remove the wall switch to paper the lounge wall with those famous last words - Don’t worry, I know where the wires go - but they forget.
So here are four common faults or problems that are created by ourselves, by the customer, or by some other tradesman that perhaps doesn’t quite understand lighting circuits.
It’s good to learn what should be done, and good to solve a problem - enjoy.
This video is No.96 on our TH-cam channel where we have videos on a wide range of electrical topics.
We also have videos on installing or extending lighting circuits as follows …

Always work safely, electricity can be dangerous. If you are unsure, stop and seek advice. This video is provided for guidance only. Every electrical situation is different, please check and ensure that you are applying this learning information to your own individual circumstances correctly and safely. If in doubt, stop and seek competent advice.
These videos should be mandatory viewing for any electrician starting out. So well explained Dave.
Well thank you very much Paul. Great feedback - makes me feel good that I'm doing something right. Spread the word. Dave.
I agree
I'm an electrical trainer and imo without a shadow of a doubt the best electrical educational Chanel on the tube 👍
Wow, that's great feedback. Spread the word. Thanks very much, really appreciated. Dave.
Absolutely you are right
I really appreciate all of your videos. Clear and concise. They were a massive help when I was on my course 👍 Thank you
That's excellent news Andrew, so glad that we helped, that was the intention with these videos. Thanks, Dave.
You're a top fella Dave. As an apprentice I muddled the strapper cable on at least a couple of occasions. I was red faced trying to figure out what I'd done wrong. It worked but not how intended. Sometimes it's the simplest mistakes. Keep doing what you're doing buddy. You're producing some mighty fine tutorials 👍.
Thanks Ray. I've lost count of the mistakes I made over the years - training days I called them. And yes, every intention of continuing the help videos. Dave.
Another very good presentation Dave, very clear, well done...!
Thank you Gary, thanks for the support. Dave.
Superb and easier understood than a lot of other books etc. its never been clear to me what way the current travels in certain switching scenarios until now. you make a seemingly complicated [ to the novice ] trade a lot easier to get my head round. I cant thank you enough and hope you keep making these videos until im old and grey.
Thank you Angela, keep learning a little every day. I am old and grey and I still learn things. Its a great trade. Dave.
Keep it up dave.. Well done.. Great as usual
Thank you. Great comments, appreciated. Dave.
This vid is a godsend. I have done all of these as a diyer and never knew how. I am now qualified and it is good to know or be reminded what causes the different scenarios.
Perfect. So glad you found it useful and thanks for watching. We never stop learning.
Electrics is a good trade to be in, there is always work and its taken me around the world.
Dave.
Thanks Dave!!!
Thanks for watching Jay. Lots more to come. Dave
Excellent channel and brilliant content by Learn Electrics.
Really happy that you like it. Thanks for your support. Dave.
excellent tutorial. my first time with this fault was a hair puller... i must have ran a marathon up and down stairs to rectify it.. more folks should watch these
We've all been there Alex. Training days I call them. Dave.
This channel has been my go to for since I started my course. I came here hoping to find a diagnosis on flicker lights but unfortunately no luck. But still thank you for all the vid tutorial greatly appreciated
Thanks for supporting the channel. We could certainly think about a video on flickering lights. Dave.
Wow! This is very informative. Thanks for sharing it with us...
My pleasure. Lots more to come. Dave.
@@learnelectrics4402 welcome Sir. You have been my number one tutorial. Your videos give me a deeper knowledge...
Thank you Dave this Videos are amazing! I also want to thank you for the website , so much good content .
Glad you like them Luca and thanks for the good comments. Dave.
Dave, Thank you 🙏.
Thanks Aman, appreciated. Dave.
Very good video
Thanks very much, great comment, appreciated.
The oddest & biggest pain in the arse I've had with lighting was installing 6 led spots in place of an old 6ft flourescent.
They worked great for about a week then all 6 started going to half brightness!! I re terminated every connection, replaced the switch drop & the issue randomly continued after a couple more days. Luckily i could easily get to the loft area. I measured ( whilst in fault mode) 188v !!! I replaced the complete circuit & feed ( from the adjacent bathroom) & all is ok. I meggered the 1.5 T&E that i removed & scrutinized it severely, & it looked perfect. I can only assume that the cable had a break down within the copper somehow !!! But it meggered ok & a low resistance test came back ok !!
Could have been leaky cable insulation, it could have been leaking to something it was touching. Sometimes these random problems remain a mystery. Almost certainly the old cable was the root of the problem. Good that its sorted.
brilliant, thanks again
My pleasure and thanks for watching.
FANTASTIC JOB. I'M REALLY A BIG FAN OF UR FABOLOUS VIDOES.
Great feedback, really appreciated. Thank you.
Wow! This is very informative, thanks for sharing it with us Dave. It worth it and the best tutorial on the topic for me...dl
Thank you, great feedback.
@@learnelectrics4402 Welcome
Nice video
Thanks, much appreciated. Dave.
hi,
With the ' it blows the fuse on switch on ' , what if the lights had not been disconnected for decorating or what ever reason for disconnected and reconnected wrong and it has just developed this fault ,
what could the issue be then ?
A short some where , but how would you go about finding where the shot is ?
is there a video like the ' Fault finding - Ring circuit ' , for the lights ?
or would it be the same method you would use as in the Fault finding - Ring circuit, continuity test first then insulation resistance?
Something has happened. Just a case of methodical fault finding. Good luck. Dave.
@@learnelectrics4402 , Hi Dave ,
Thanks for your reply , what methodical fault finding method would you use ?
would it be the same method used as in the Fault finding - Ring circuit, continuity test first then insulation resistance?
or is that just for Ring circuit for sockets ?
Brill explanation
Thanks for watching. Dave.
Useful thankyou! What about a 2-way switch where only one orientation of switches work?
So there’s only 1 out of the 4 possible ways of having the switches that works.
Is that a problem with the switch itself?
That sounds like a wiring fault, check that your wires are going to the correct terminals. Have another look at the video, a scenario like that is covered. Thanks for watching. Dave.
Hi, I replaced the switch and it started working properly again. Your video gave me the theoretical knowledge to realise that one of the switches must be the issue, and also demonstrated the patience required to find faults. Thank you for this informative video. I’ll be back for any more electrical issues in the future!
I usually get. It’s always been like it, never been touched. £60, thank you.😂👍🏻
Oh yes Mark. The great Nobody. But it makes no difference to the end bill.
Thanks for watching. Dave.
Hello, What is the minimum size of an aluminium conductor which feed a lighting circuit, 16mm² or 1.5mm². In OSG, table I1, aluminium cable only begins with the size of 16mm²
Correct. Table 52.3 page 148 of the Regs book. Be careful with old aluminium cables as they become brittle and can snap as you bend them. And remember to dip them in an anti-galvanic compound before putting them in brass terminals. Sometimes best to try and rewire that part of the circuit in copper if possible. Dave.
Great content as usual. Fault-finding techniques for RFCs would be very useful. BTW, what software are you using for your diagrams?
I just use powerpoint. I used to use CorelDraw until about twenty years ago and thinking about going back to it. But I've been thinking for two years now. Thanks for watching.
Been sparking for over 40 years so not sure why I watched this but I liked it.
I'm the same, there is always the chance we see something new. Thanks for watching anyway, it is appreciated. Dave.
I want to learn every electrical troubleshooting. How it is possible? Can you inform me sir? I will be very greatfull to you.
Thank you very much
Seriously, watch all the learnElectrics videos. You can also search for them on LearnElectrics.com, almost 200 item. Watch a video every day and just keep learning.
Going one
Thanks for watching, appreciated. Dave.
