This video shows how to Measure Back of Bend, Double Sets and Running Couplers in Steel Conduit. A learning guide for apprentices, refresher for electricians and AM2s Candidates.
This was an awesome video. Very well done
Thank you ... hope it was helpful for you 😀
True
Hello John not too sure if you look at the comments but I was in your refresher course on the 10&11/12/20 and just wanted to say I smashed my conduit because of you and I appreciate all the help you gave me. Anyone reading this just make sure to watch it as much as you need because it’s the best explanation out there. Thanks again John!
Thank you for the feedback Jake ... glad to have helped. 😀👍🏻
That's respect and yes great video simple and clean 💯💞
Pretty cool to see how it's done in other parts of the world. Thanks for the video
Just doing my Am2s you've just saved me retaking it with this video 👌
Good Luck 👍🏻
@@michaelsebastian1990 well done 😀👏🏻👏🏻
Excellent detail & instruction, thank you. 🙏🏻
Great video on Conduit Bending just what was needed on KZhead as there is a lack of decent conduit bending videos around Thanks
Thank you ... hope you find it useful 😃
Yep decent clip there..well done
That was excellent just what I needed not enough videos on conduit bending for uk electricians,apprentices,adult trainees it seems to be all American with the Klein bender keep them videos coming guys its very important and helpful thanks for sharing 👍
Mark Andrews Thank you for your comment ... 👍🏻
"american" way is faster.
@@pokechamp003 I agree with you I have used the Klein bender before and I did like it but getting a 20mm or 25mm shoe in the uk is very expensive and when we have to thread the ends to fit the coupler we need a vice I believe the American version of the coupler is push fit also a better idea
Very clear and easy to follow demonstration
I just recently passed my am2s assessment and want to say thanks. Your videos were very helpful in my preparation.
Congratulations on your pass 👏🏻👏🏻.. glad to have helped
How was it??? Mines been pushed forward to Monday
Came for the conduit, stayed for the music 🔥
😂 … licence free rock n roll 😎
Nice tip about scoring the conduit for the thread line.
Works for me 😀
Very helpful demo, thanks
john was my jtl assessor 10 years ago. never thought i'd see him on youtube 😂
Old dog with old tricks 😂
Excellent video, surprising why you don't have a lot more views.👍
Appreciate your generosity
We need more uploads mate. This is a great video! Could you do one about plastic conduit?
It’s definitely on my list .. bubble set ..
Very detailed video. 👌 Much appreciated.
Super useful !! Thanks very much for taking the time to put this together - very nicely done too :-)
Great informative video 👌👍
🙏
great video. keep posting
The best demonstration on youtube.
Thank you very much. I hope it was useful for you🙂
currently doing some tube at home, this is great! thank you so much. Would you be able to do a tutorial on bubble sets - if possible - next please!
Thank you for the positive feedback, always appreciated. We do have plans for more videos, and Bubble Sets are on the list. 👍🏼
When do you think the bubble set video will be released?
great video. really useful

This brings bk memories of browsing.
Good video - thanks
Good demo.
Nice 1 mate
Thanks 🙏
New subscriber. My metal munching experience is basic at best so I need more conduit tips please
Hoping to add a PVC Bubble set soon
@@headsup4sparkies I'm here for the metal munching sir... PVC conduit bending isn't exactly known as an art 🤣
Great masterji tussi great ho
Excellent video, can i ask how you added the bitmoji?
Hi .. recorded from iPhone as message .. downloaded and added as an overlay at edit ... hope you found the video useful 😃
Thanks a lot ☺️❤️❤️
Hi, great video. I’m currently waiting for my am2s and any help with pvc conduit, or what’s required with it would be appreciated. Thanks
You will need to be able to do a bubble set .. with the set symmetrical about the obstacle with a minimum and maximum clearance 😀
Great job
🙏
Great video
Thank you 😀
Just a question - with regards to the depth of your double set - you’ve been quite accurate with your measures - 53 mm - and here’s my question - do we not need to take into account the depth of the saddle ? They’re usually around 3mm and up deep. I’m learning - it’s just something that caught my eye :)
Hi … you are correct, and you would want to consider saddle depth, particularly for saddles deeper than spacer bar saddles. Generally a few mm’s here and there can be easily tweaked as shown in the video. Most wall corners aren’t exactly 90 degrees, bending millimetre perfect is unlikely .. the important thing is to be as accurate as you can and allow yourself a little to play with. Then “offer up” the bent conduit in position and tweak it as required. This is aimed at the AM2s, where you have one chance to complete the pipe in one piece … so they give you tolerances in the marking. Getting the right distance between the set & 90 is key, leave the coupler cuts to the end .. 👍🏻
great video thank you
🙏
It's very good videos Thank you
🙏
Dear Heads you are a Great Engineer
thanks!! very useful video!
Thank you …
We have threaded pipe in the US (rigid metal conduit and intermediate metal conduit), but there's a lack of videos available online on how to assemble the entire run from start to finish. It's especially challenging, IMO from point to point and against surfaces, where we're taught to spin on the whole conduit run. Else, we're encouraged to use some sort of specializing fitting in tight situations above with a 3 piece coupling, or a threadless connector. This method you've shown avoids such things with a running coupler and the other end with a coupler/male bush, which don't require specialized fittings and makes everything straightforward overall. Thanks for making this video.
Glad you’ve found it useful … from what I can see on KZhead - US bending machines are a lot more robust than ours … we have also seen a few “slip-lock” type fittings reappearing in the UK recently … but I hope that the old school conduit skills never leave the industry 😀
Got my Am2s coming up this has been a massive help! Are these measurements the same as the AM2s on the day or your own made up ones thanks!
Thank you for your comment. The measurements on this video are specific to the job in hand, however the requirements for the AM2s are similar to the task in this video. Therefore this video shows you all the techniques and planning that you will need in your assessment. Good luck 👌🏻🤞🏻😀
Ok thanks again 👍🏼
Good lesson
This is very helpful. Thanks a lot. I sub!
🙏
When is the next video matey need the knowledge having withdrawal symptoms
Very good work
Thanks for share
Just a quick question if the depth was say higher or lower than 53mm would you shorten or add more on too the 100mm in between the sets ?
You can increase the depth of the set by either making the 2 bends deeper, or by increasing the distance between the bends. In the AM2s there is a maximum length that the set can be, detailed in the spec. When setting out your bends you will need to decide what looks best and fits best in each circumstance. Hope this helps ..
Great video but how do you know when doing the 1st and 2nd bends on set where bend starts on former please!?
When the conduit is resting in the former, the bend will be at the point where the conduit and former separate (underneath) … I generally place my little finger underneath to “feel” where that point is - and try to get the mark in the conduit at that point.. However - you don’t have to get it exactly right, as you can simply adjust the depth of the set. To add depth, put a little more in each bend. To decrease the depth, take a little out of each bend. Making sure to adjust the existing bend and NOT putting and additional bend in. Some people attempt to “mark” the former on top at the “point of bend” but you often have to change the position of the “stock” to get the measured conduit mark where you need it - as soon as you do this, the mark on the former will now be in the wrong place. Try not to over think it - bending conduit is more of a knack than an exact science. The ability to manipulate the bends neatly is the main skill. Practice makes perfect 👌🏻
Hi, got my am2 Monday I'm pretty confident on all aspects but my lack of fault finding is where I'm struggling do you have any tips or anything I should watch or read before the fault finding test part? Thanks
There are videos on fault finding (mine will follow soon I hope) that can help.. but fault finding is really a test of your knowledge of circuits and testing. Listen carefully to the symptoms and look at the state of the protective device .. this should tell you the type of fault you are looking at. Then make sure you locate it correctly .. you haven’t found it until you can identify it between 2 positions, if you have a short and you split the circuit in the middle, the fault will still show on one of the cables there, that doesn’t mean the fault is at that point - keep splitting until you find it at both ends of one piece of cable. Also - when looking for shorts to earth - NEVER DISCONNECT THE CPC’s at the MET .. the fault is on one of the live conductors !! .. Good luck
@@headsup4sparkies Thank you I absolutely nailed my build I had this band and the S plan to do today with 5 hours to spare I done it! This video helped so much appreciate your time to make it👍 I'm doing my fault finding and online exam tomorrow I'm abit worried about the fault finding if I'm honest
very nice
Exelente video amigo soy electrisista desde costa rica.... Yo para aser cambios de direccion o offset.. Tengo mi forma y se trata de tomar medida usar calculo con el teorema de pitagoras y centro marca dobladora y sale super biem amigo
Gracias por tu bonito comentario. Me alegro de que te haya gustado mi vídeo. Diferentes naciones tienen diferentes formas de compensar. Creo que Estados Unidos también usa cálculos de Pitágoras. En Inglaterra, nuestras dobladoras no son muy precisas, por lo que las marcas fijas no funcionan tan bien para nosotros. Este método es más común en Inglaterra. Es fantástico para mí recibir mensajes tan lejos de mi casa. Muchas gracias.

Great. Video, thank you!
How do you know exactly where to put the mark in the former after measuring 53mm?
That’s the beauty of leaving the coupler cut till last ... I gave myself a 70mm margin of error and only needed to worry about the depth of the set, and not the position of it, initially .. therefore placing the mark at the approximate point of bend on the former is sufficient.
very good
How do i bend really a long piece of conduit (4m) in the middle. I need a 90 degree bend but the end will hit the floor. Thanks
Hi ... the most common way to bend a long length is upwards. Using the bender in exactly the same way, except that the stock and bending arm will be at the bottom of the former, and you bend the conduit upwards .. hope this helps
@@headsup4sparkies thank you for the reply. Do you know which brands can do this as i see some that state maximum lengths of 1100mm so I'm assuming not all can work upside down
cdn11.bigcommerce.com/s-7holhynnib/images/stencil/original/products/50562/40912/5adab7f8ee8a76000e5dfa02__88558.1583489141.jpg?c=2&imbypass=on&imbypass=on ... any bending machine that looks like the one in this video, can bend upwards. The link shows an image with the Stop & Bending Lever hanging under the former. Place a foot on the bending machine and pull up to bend.
@@headsup4sparkies thank you for your time and patience in answering my question. You've been a great help. I managed to hire a machine from HSS and it bent my long conduit upwards as you said. You've been a great help.
You’re welcome ... well done 👍
Super
where you had the running coupler and lock ring can you not just measure say half of the coupler so that when you tighten up the running coupler with the end you wont have any tread showing ?
I’m afraid not .. the running coupler needs to run from one piece onto the next piece. Therefore it will always leave some thread behind it. The way it’s shown leaves half the thread on the existing piece, and puts half the thread on the new piece. Therefore leaving half the thread exposed on the back of the existing piece, with both ends electrically (earthing) and mechanically secure.
@@headsup4sparkies ah yeah makes sense now thank you
@@headsup4sparkies also the nipple part you threaded into the box is this something for the am2 that they will provide ?
Where can I find that bending station
Pretty much any UK electrical wholesaler … here’s a link from a quick search www.toolstop.co.uk/irwin-hilmor-el32-conduit-bending-machine-with-vice-and-20-25-32mm-formers-t113100d-p80043/
What is the name of this bender? Where can I buy it from?
There are different names, but I think the most common in the UK is made by Hilmor .. here’s is an example link from a UK wholesaler .. www.tlc-direct.co.uk/Main_Index/Conduit_Steel_Index/Conduit_Bender/index.html?ad_position=&source=adwords&ad_id=414374435730&placement=&kw=&network=g&matchtype=&ad_type=&product_id=&product_partition_id=&version=finalurl_v3&gclid=Cj0KCQiAwqCOBhCdARIsAEPyW9lmDNmlUux6qJls7H9S6mp5RPNTMG9YdOS4OYPuVNj5bmCCiSHvCiQaAn33EALw_wcB
Cual es el modelo y la marca de la dobladora

You should voice an animated movie character. (I am not joking)
Why not just use a battery powered porta band saw to cut the pipe and a hand bender.also when bending offsets you can just eye them from experience or just use the multiplier for the degree of bend to make the marks ..with a small bend like that I wouldn’t even measure it .you can just bend it and lay it flat on the floor also to check the height and then grab a tape measure to see if you have the right height if eyeing it as well as making sure it’s in the same plane .
Hi Chris … this is all true …. However, this video is aimed at apprentices with little conduit experience, who are taking their AM2s exam. Where they have one attempt to complete a piece of conduit without a coupler between the bends, with only these tools available to them. They’re work will be closely examined and must come with-in the tolerances allowed in the marking criteria. Competent and experienced electricians like yourself, would not find this task challenging, but for electricians less experienced with steel conduit, it is useful to have a reminder of the basic skills required.
When measuring the 53mm you didn't take into consideration the depth of the saddle base (5mm) so it should have been 48mm!!
That is true - good spot ... although I was using spacer bar saddles which are only a 3mm base. I left that bit out for clarity as conduit bending is not an exact science and most sets need a little “tweaking” to sit perfectly 👍🏻
Good video,but you did not allow for the saddle heights in your calculations
I know ... I didn’t want to complicate it - I used spacer bar saddles so it’s only a couple of mil - and as it happens.. it fitted nicely (walls clearly not that square 😀) .. Thank you for the feedback .. I should be posted an S-Plan Heating wiring connections very soon.
@@headsup4sparkies How soon please 👀
Wasting 4 inch of pipe I would get battered by my tradesman back in the day 😂
😂🤣
Also why didn't you start with the coupler end ? Just created more work for yourself . Crazy!!
The video is primarily aimed at students taking AM2s exams. Leaving the couplers as the last cut is the safest way to ensure accuracy. Particularly when you have a finite length of conduit and limited time to complete.
Americans use a Union...a lot neater and faster to install...
American conduit installations and equipment does differ quite a lot to our UK methods. More Robust and accurate bending machines and a more “mathematical” approach to setting out bends. We do use Unions occasionally, usually only in explosive Zones (Ex fittings). Here’s a link for any UK electricians reading this .. www.eaton.com/content/dam/eaton/products/conduit-cable-and-wire-management/crouse-hinds/catalog-pages/crouse-hinds-unf-unl-uny-unions-el-elbows-catalog-page.pdf . Thank you James for your comment 😀
They do a lot more conduit compared to us in UK.. working there for 10yrs the biggest one I worked with was 6" conduit...Fortunately I was old enough to remember imperial units which helped me a lot.. Still think we do a neater installation in UK ...that's my opinion ...
christ ! - kill the music and the avatar... then you've got a great video !
Super
