I learn more by watching Johns videos than i do in hours at college and on expensive courses... his no nonsense to the point explanations are a great example of how to teach... i wish all tutors could follow this guys example.
Not only is this guy knowledgeable in his field (electrics). But he has also mastered the art of teaching and RUclips video presentation.
I take my hat off to you sir! much respect 👏🏽
Lovely geezer , he sounds like the 2x speed option on the videos
Big Clive is awesome too.
A much better instructional video than others I’ve watched John. No banging music and silliness. I’m now confident enough to install all my new shed wiring with swa and not have to worry about slack professionals. Thank you.
This Man is gifted when its comes to explaining electric staff.
Very helpful, the wrap of insulation tape was spot on.
Glanding SWA is one of my favourite jobs, I find it very therapeutic, I could happily do it all day. Great video as always JW.
Excellent tutorial video and put me straight onto the right track for running an outside lighting circuit using 1.5mm 3-core SWA. I gave the hacksaw scoring method a try but found it a tad awkward, especially when standing on top of a ladder! Job was quicker and neater with a standard plumbing pipe cutter and as I have a couple of them didn't cost any extra in new toys.
I will have a look at some of your other vids to pick up more useful tips - hope you're making money from the hard work you're putting in to share your knowledge.
I’m a Trainer - but am in awe of Johns fantastic training videos
thanks John for the great video. it`s always fun watching you work
Super instructional video . At 20.05 I am now aware of why my garden light failed . On inspection I discovered that the wires were completely coiled up and a couple broke over time . A simple error for a DIYer but at least now I can correct thanks to your excellent tuition . Many thanks .
I actually stumbled across this whilst trying to find out whether to have a separate premises earth for a garden room, and ended up watching all the way through. What an excellent tutorial!!
Takes me back 30 years to my BT power section apprenticeship at their Paul Street training centre. We learnt how to strip and terminate Mineral Insulated Copper Clad fire alarm cable that week too... #flashback
Excellent, thorough video. "Now you just strip off the bedding...". That's what I wanted to see you do, safely! Also the standard technique for cutting the boot is to pull it hard on to the end of the cable, and cutting it off where you can see it is slightly deformed. You did that, Blue Peter style, off camera.
Very informative and professionally presented, thank you John.
Excellent video. I'm an electronics engineer and I've just installed the 'electrics' into an outside building. The only thing I wasn't sure about was terminating the armoured cable. Now I know. Thanks for an excellent, clear, thorough tutorial.
Naturally you had it signed off 😉
Excellent video. Very clear from beginning to end with all points covered.
Great Video. 100% accurate with clear step-by-step instructions.
I'm sure this will help a lot of people out as there is a lot more involved in terminating armoured cable as opposed to other typed of cable like twin and earth etc
And yes we have all seen shocking terminated armoured cable jobs in our time
Another great video!!! Thanks so much for passing in your knowledge
nice video, good to see you using all the correct practice when demonstrating how to connect the cable. the amount of times i see this done wrong, it pisses me off, when i see these installed and the person has decided not to use a ring crimp terminal on the earth tag, just wrap the wire around the screw and tighten it up. you pull on the wire and it just untwists off the screw.
I know someone who uses pop rivet to secure the ring terminal onto the earth tag, no no no. these rivets are mate of aluminium and they corrode very quickly in any type of moister, I measured Zs on a cable like this and got 4 ohms. because the rivet had oxidised and caused loads of white powder between the connection.
and probably my least favorite is when you see the use of a plastic IP gland on swa cable and just taken one strand of the wire armour and put in into a terminal block, very poor. and it really gets on my nerves.
Brilliant explanation. Thanks John, I love learning from your videos. For those saying it's difficult to make the hacksaw cut, why not use a junior hacksaw with a sharp blade, surely has to be easier than a full size frame.
Big help for me thank you. You answered all the questions I had regarding the armour and earthing. Cheers.
Very helpful video from someone who knows what they're talking about... and a dry sense of humour as a bonus. Thank you.
I'm not even an electrician and I find this very interesting.
Brilliant...... very good teacher/demonstrator. I understood everything and you were very specific and concise, thank you.
Great camera work where I could follow your narrative, top bloke.
Excellent explanation and instruction - patiently goes through whole sequence, covering each step in detail. Thank you very much.
Good video ,clear and not rushed!
Top video. I usually slide a piece of outer sheath over the dust cover, then make the cut a couple mm above, it makes for a spot on cut and a tight fitting glad cover
All of your videos are excellent & well explained.
Cheers John
Excellent John.
Thanks for sharing
Another really informative video - thanks John.
Excellent video John, just what I was looking for. Thanks.
A really well presented tutorial. Thank you.
A very thorough and extremely well explained video. Excellent.
Just the right amount of information. Really good video. Thank you
Excellent video, clear, concise and informative. Good sound and picture quality. Many Thanks for going to the trouble to pass on your knowledge and experience.
Excellent video, thank you John
Superbly useful video. Great pace of delivery. Thank you 👍🏻👍🏻👍🏻
Excellent tutorial confident now to wire up shed. Thank you.
Incredibly helpful. Many thanks!
Fantastic video john, well presented. Has cleared up a few questions i had about wiring swa cable. Top job
Excellent tutorial, this guy is a natural ! his voice sounds like the BBC from the 70's. Brilliant, have installed a SWA to my shed, thanks A+++
Hi John, something very satisfying about working with SWA it's also tricky to get it right every time,
You showed how to make a strong reliable connection
Good job
Kind regards Warren
Great video, very concise.
I do find using a hacksaw on site a little cumbersome and fiddly and so I use a 'Plumbers Adjustable Copper Pipe Tube Cutter' that will cut the plastic outer and score the wire accurately in a matter of seconds.
Keep up the good work John, I look forward to each new video and particularly the Teardowns.
I'll be making a contribution via Patreon. Cheers.
Really helpful video. Thank you for taking the time
I noticed a recent installation where banjo is fitted on outside and the drilled hole + thru brass bolt used to feed to internal earth on plastic consumer unit. This strikes me as giving better conduction path than clamping using the steel gland nut but maybe OTT given this is all connecting to the steel armor. Excellent video BTW - very clear.
Very good, informative video, thanks.
I choose to solder an earthing cable to the banjo (before fitting to the gland of course!)
Thank you, would not have managed this task without your excellent video. Used this SWA cable for fish pond, may have over speced using this cable. But following your video, at least I know it is correct and safe.
Agreed- an excellent and easy to follow demonstration
Excellent video, great voice for presentation, clear and easy to listen to. Thanks
Quite simply superb. Far from superficial .. this video covers everything that you will need to know about terminating SWA; the level of detail is immaculate. I wish it had been available when I put swa to my garage 15 years ago!! (wrongly, but I am about to upgrade the installation following this tutorial)

John this video is great! Thank you
Just about the best instructional video I’ve seen, great job thank you
Here's a tip : At 19:30 when you have the wires pushed up as far as they will go mark it with a marker on the cable insulation to ensure that you don't "lose" the armour shielding out of the gland as you tighten the nut. Same concept as when you glue up PVC ensure you are fully home
explained very well, Thank You.
Great video John
Great demonstration thanks 👍
Excellent video. I personally no longer install SWA into anything plastic, but I do fit the brass banjo regardless. Many metal junction boxes do not have an earth terminal, and relying on just the gland alone to ground the box seems inadequate. By using the banjo you are able to link the earth core, the metal box and the armouring all together.
Brilliant vid! Thanks so much.
great video JW!! thank you
The black "plastic cup" or "dust cap" that you show at (6:38), we always used to call them "boots". I don't know if this is a common term amongst other sparkies but was certainly common to us lot in the fire alarm industry.
Another enjoyable vid. Thanks, JW.
Also, at (7:55), we called that brass ring an "olive". I guess not a strictly accurate moniker, the ring not being symmetrical like a proper olive you might find in a Pyro compression gland. (Or in a plumbers' copper pipe fittings, for that matter). I suppose it's like, half an olive.
Really helpful guide ... as are all your videos: thanks!
Excellent mate. I've learnt a lot about SWA cable and fitting them now. 😁👌
Superb instructional video - recommended !
Nice video, very concise.
JW, fantastic video as always, In fact I shall be be marshalling apprentices to watch some of you media as I believe it is of sadly a higher quality than what they are taught at college.
Of a personal opinion, I particularly enjoy watching your videos of old switchgear and cabling please keep it coming!
Very well explained, Many thanks.
Really helpful video. Thanks so much!
John,Really enjoy your videos. In fact, if you'd have been one of my instructors/lecturers during my early years (in the 70's), I'd have probably opted for life as a Sparky as opposed to a Clanky. Really hope the videos bring you the commercial success you deserve, or the satisfaction that I and many others obviously derive from them.
Great video. Good to know that the normal practice is black becomes earth (green&yellow) and grey becomes neutral (blue)
Thank you for this. I’ve looked high and low to see how to earth Swa cable.
You’re my
Man John.
Excellent tutorial.
Very thorough video. Might have been worthwhile expanding on the use of the BW glands, as they're not provided with an olive and could lead to people thinking they're missing from the kit.
Very therapeutic videos and & tutorials,, I Salute You :)
Best of luck to you trying to do it neatly and easily as this in the field!
JW - thank you for this video and in fact all of them, they have enabled me to proceed with confidence in running power to my new wooden workshop (which has no extraneous metal parts) which is 30 metres from the house consumer unit. Fortunately, my consumer unit had spare ways but on the downside is a plastic unit. I have fitted a BG consumer unit in the workshop with an RCD, one 32A MCB (Type C) and one 6A (Type B) MCB. I watched this SWA cable video a few times and most recently after running the 3 core 6mm2 SWA cable which took a whole day (a circuitous route!) - by the time I got to the workshop I had 2 metres spare so had an opportunity to have a practice SWA gland termination. It all went swimmingly well and I now have a really good ‘pattern’ to ensure I make a perfect termination for the final assembly, where there is little room for error.😳 I have reservations about terminating the SWA at the supplying consumer unit as it is a plastic one - is it worth using an aluminium backing plate to spread the mechanical load of the gland and cable - I will of course be clipping the cable well -but there is still a residual mechanical load particularly while manipulating everything into place.
Metal plate would do, or the more usual method is to fix a small metal box next to the consumer unit and fix the gland into that, such as www.toolstation.com/shop/p15062
Got it - simple when you know how - I will get one of those. Thanks JW - perfecto :-)
What an excellent tutorial.
An excellent demonstration. I would add one point. If terminating into a steel enclosure such as a distribution board, it is usually necessary to carefully remove any paint around the entry hole, exposing clean metal, to ensure good earth continuity between the enclosure and the gland. Coarse emery paper is probably the easiest for this.
Brilliant video, thank you
Are there any different earthing requirements when connecting SWA to a TNS or TNCS supply at the CU end.
A good tutorial, thanks.
nice neat job, well done sir.
John, great video as always. I plan on wiring up my garage at the house I just bought, and was wondering the best way to do it.The garage is 5 metres away from the house and I have plenty of SWA, but I don't want this going into the CU. Can I run T&E to a jcn box on the outside wall, then SWA to the garage into the CU in there? Would 2.5mm2 would be the wrong size from the CU to the jcn box? I am planning on running a ring of twin sockets in the garage, and a single lighting circuit.
Thanks in advance
Fantastic job
Thanks for the video.
John, can you do a video about mineral insulated cable?
