Great video!! As always! Please do some practical videos where you explain 3 plate method, 2 plate, how to find the switch line etc. Just things you come across on the job, that would be excellent. Thanks again 🙌🏾
Great video, I am very grateful. One quick question, in the ring circuit after FCU with 1.5mm square cable, Zs is going to be reasonably heigher. What would be the max Zs acceptable for this circuit?
More a curious question here if you may. How would you explain the need for the spurred cable from double socket to be 4mm to FCU if the load will never be more than what is after the FCU due to the 13A fuse? Is this something to do with under fault conditions if that cable got damaged or something? Thanks!
Thank you once again for a great video. I am wondering if on a ring circuit wired in 2.5mm can we spur off with 4mm cable and create a series of sockets wired in radial using the 4mm cable?
Great video and many thanks. I have a question if I may. We are wanting to add more sockets in our kitchen but unsure if it is a radial or a ring cicuit, so don't want to risk adding more than one cocket if it is a ring circuit. What is the best way to add 3 sockets without knowing whether it is a ring or radial. Do we add an FCU and then connect 3 sockets to that? Many thanks in advance. it will be REALLY HELPFUL x
Sarah, if you don't know what type of circuit it is then you have to assume it could be a ring and that then limits socket additions to just one accessory without using a fused spur rated at 13 amps. Once the fused spur (FCU) is installed you can take as many sockets off the FCU as you wish because you are limited to 13 amps max current along that line. Hope this helps. Dave.
Awesome . May I ask a question please . I have o e socket in my garaje coming directly from the consumer unit , so it’s a radial circuit . I have taken two spurs off that socket by the way of an MK logic rapid fit face plate. I have 3 sockets on each spur out . So my question is the RCD fitted is 16amp, but your video says I should use 20amp. Should I upgrade it ? I am using the correct 2.5mm cable .
I think you mean the circuit breaker is 16 amp, not the RCD. Your 16 amp breaker is fine. 16 or 20 are out with 2.5 cable on radials, no need to change. Dave.
Love these videos, but I have a question. Today I attended a Napit exams and it started with some multiple choice questions. Question was ‘ how many sockets can be installed after a non switched fused spur on ring final circuit’ I got it wrong. Apparently it only 1 can be installed. Do you think this is correct?
Based on what you have written, I know that it is not correct. Look at page 505 of the Wiring Regs book. At the 3 o-clock position on the diagram, it clearly shows more than one socket connected to a non switched fused spur, along with confirmatory words. Hope this helps, especially if your success in the exams depended on this question. Good luck, Dave.
Hi Dave, just a quick update. I have checked a course provider and below is the qualification I'll gain doing the 9 week course: Building regs 18th edition 2391-50 2391-51 Will this be sufficient enough for me to get on to a scheme, or do I need further qualifications. Thanks
You also need proof of two years work experience. To get the experience lots of people just do minor works jobs which do not need you to be registered. Take loads of photos of your work, issue a Minor Works Certificate for every job, however small. The photos and the Certificates will be your proof of two years work. I know a few sparkies who only do Minor Works and are making in excess of £500 a day. Also, check out Napit or NICEIC website for the latest joining requirements. Good luck. Dave.
Definitely. Anything downstream of a fused spur will lose power if the fuse goes, if the circuit is wired correctly. Take a look at this video on radial socket spurs. Lots more info. Thanks for watching. Dave. ua-cam.com/video/Et7CpEwFEzg/v-deo.html

Thank you for the time and effort you put into your tutorials and making them available.
You are very welcome Alex.
Thank you for keeping it simples!
Thank you, great feedback.
really good clarity on radials in particular for me thanks guys, 👍👍

Thanks Simon, great feedback. Dave.
Again guys, brilliant as always. 👍
Much appreciated comment, thanks. Dave.

Good idea David. Its in the thinking pot. Thanks for the feedback. Dave.
Incredibly simple and very clear thanks
Thanks for the great comment Grant. Appreciated.
Could you do a video on time delay rcd's how to test them and how they are used, please
That is actually in the pipeline Alan, thanks for asking. Dave.
Wow! This is very informative, thanks for sharing it with us. It worth it and the best tutorial on the topic for me...dl
Glad you enjoyed it and thanks.
Thank you for your efforts. Appreciated
You are very welcome. Lots more to come, in fact next video tomorrow. Cheers. Dave.
absolutely amazing videos and amazing explanations !
Thank you Moammal, and thanks for watching. Dave.
Very useful
Thanks Paul, much appreciated comments, Dave.
Thanks Dave your time
You are very welcome, glad you enjoy the videos. Dave.
Brilliant and explained well.
Thank you, great feedback. Dave.
Very clear, thanks.
Thank you Mark.
Excellent sir 🙏👌
Thanks for the nice positive feedback. Dave.
Nice one mate
Thank you Amri. Happy to help.
Hi Dave, @2:38, is there a typo? 4mm square before FCU should be 2.5mm square? Although 4mm square is still acceptable but not necessary.
Yes, another of my famous typos. It should be 2.5 but as you say, 4mm is acceptable too, but not necessary. thanks for that, much appreciated. Dave.
Great video, I am very grateful. One quick question, in the ring circuit after FCU with 1.5mm square cable, Zs is going to be reasonably heigher. What would be the max Zs acceptable for this circuit?
Zs is determined by the breaker or fuse rating, not by the cable size. There is nothing to stop you using 2.5 after the FCU if you wish. Dave.
More a curious question here if you may. How would you explain the need for the spurred cable from double socket to be 4mm to FCU if the load will never be more than what is after the FCU due to the 13A fuse? Is this something to do with under fault conditions if that cable got damaged or something? Thanks!
Exactly that. The cable is not protected by the fuse until AFTER the fuse. Thanks for the input. Dave.
Hi, great videos. Quick question..on a ring circuit, after a 13A fused spur you mention the cable size is 1.5mm. Can it still be 2.5mm with no issues?
Definitely Ashley, 1.5mm is the smallest. 2.5mm is fine. Thanks for watching, Dave.
Thank you once again for a great video. I am wondering if on a ring circuit wired in 2.5mm can we spur off with 4mm cable and create a series of sockets wired in radial using the 4mm cable?
If you use a 13 amp fused connection unit to come off the ring BEFORE any sockets then yes.
If not, then no.
Hope this helps. Dave.
@@learnelectrics4402 yes it is clear thank you.

@@learnelectrics4402 yes I mean circuit breaker. Thanks Dave . I found your other video after which covered this . Subscribed !
Question; when dropping down after an FCU does it have to be 1.5 or can it remain 2.5mm
Thanks
Absolutely it can be 2.5. Thanks for watching Paul.

if the fuse in the spur blows, would the sockets attached to it after stop working too?
Definitely. Anything downstream of a fused spur will lose power if the fuse goes, if the circuit is wired correctly.

@@learnelectrics4402 Thanks Dave, appreciate your response. Keep up the good content 👌🏼
Silly question, Can you do a spur from a light switch to a socket?
No. first its not good practice to go lighting to power. Second, there is no neutral in the light switch. Hope this helps. Dave.
