Electrician's use a Box Offset bend anytime they need to feed an electrical box with conduit. it is one of the more basic bend they make just about every day of the week. I'll step you though how to make one.
In this video I will show you one way to make a Box Offset Bend in a ½ inch EMT conduit using a hand conduit bender from IDEAL.
A Box Offset Bend is needed anytime an electrician needs to feed an electrical box with a piece of conduit. The knockout on the electrical box is not flush with the back of the box hence the conduit must be bent slightly so it can be inserted into the conduit fitting attached to the box. This allows the conduit to be mounted properly to the wall without putting undue stress on the conduit fitting.
For this demonstration I will use our catalog number 74 - 026 Ductile iron head bender from IDEAL. The ductile iron head benders are typically preferred by the professionals as they will last longer than aluminum bender heads which are lighter weight but less durable.
Generally a 10° offset Bend is used to create this box offset. If you remember my video on offset bends a certain shrink amount and a multiplier is used to create the offset.
On 10° offset bends the shrink amount is 1/16 of an inch for every inch of obstruction and the multiplier is six which is used to calculate the distance between the two bends I need to make.
On a typical electrical box the knockout is about 3/8 of an inch away from the back of the box which becomes the height of the obstruction we need to overcome. Six times 3/8” is 2 ¼” which becomes the distance between the two bends on the conduit I will make. The shrink amount is so small it is not a factor.
To make the box offset on the end of a piece of conduit I will make two marks.
Step one is to make the 1st mark at about 2 ½ inches from the end of the conduit. If I make the mark any closer to the end of the conduit the hook of the bender head may deform the round shape of the end of the conduit and not fit inside the conduit fitting on the box.
Contractors generally use a pencil to mark the conduit so it can be erased later. In my example I will use a permanent marker and mark the conduit all the way around so the mark will not get lost in the conduit head when bending.
For the 3/8” offset we calculated the distance between bends to be 2 ¼ inches. So I’ll make a second mark 2 ¼” away from the first mark and mark the conduit all the way around.
Offset bends are done in the air not on the ground. Simply stand the bender with the handle pointing down and bender head closer to you.
Step two is to insert the conduit into the bender head and lineup the first mark with the arrow on the bender head. Bend your knees to lower your center of gravity and place 1 foot up against the bender handle to keep it from slipping. Then using constant pressure close to the bender head, bend the conduit to the 10° mark. The bottom of the conduit will be even with the mark.
Step three is to slide the conduit down to the second mark and line it up with the arrow on the bender head. Rotate the conduit 180° and align the first bend with the second bend sighting down the bender handle. Then bend the conduit to 10° again.
This creates the box offset in the conduit that allows it to easily slide into the conduit fitting on the box.
Knowing how to make a box offset bend quickly and efficiently will make those jobs run that much smoother and add value to what you can do.
Electricians don’t bend the conduit and then cut it to the correct length. Once they know how to use a bender correctly the conduit is the correct length for the job. Using a good quality hand conduit bender like this one from IDEAL will provide accurate and professional looking bends that electricians expect while on the job.

Thanks for watching folks I’m Ron with IDEAL and see you on the next one.

Sitting in the port-a-potty watching this because I told my boss I knew how to do this and I hella forgot lol
Take your time! Ron
@@Bimmstar hilarious, I just learned 2 days ago. Got that shit down now!
Watch out some of those guys mess with you sitting in a port-a potty too long on a job site. When I was in high school (laborer job) if you were in there more then 5 min someone would stick a scrap piece of wood in handle couldn't open it rocket back and forth splash sewage on you. If had to use it look around see if anyone was looking notice you near it. Go fast before they find out you were in there.
this! If it don’t use it, ya lose it.
I am a first year electrical student and we’re going over conduit bending this week. I have been struggling with box offsets the most and this video was very helpful, thank you~!!
Hi Kathryn good to hear from you there are not enough women in the trade so glad to see you enrolled. Bending conduit take a lot of practice but once you have it down you will do well. Ron
Would think they teach you conduit bending always wanted to be an electrician but too late now I'm in my 50's went with IT work. I see lot of young guys in their first year of apprenticing bending conduit when we are remolding, or new buildings. Would have by own business by now would get into solar contracting. That is the future solar going to be installed on every home when sodium ion battery get cheap no fire risk, and sodium is cheap to mass produce.
Great presentation. I am a retired journeyman electrician but I always enjoy these videos which kind of help me remember how much fun I had being an electrician. My specialty was heavy industrial and loved working and troubleshooting motor control circuits as well as VFD's.
heffo loved your "StairwayTo Heaven" thanks for watching
Why do we need to offset the conduit ?
heffo and juff wow you loved being an electrician! I’m a 52 YO HVAC tech and love my job as well and constantly watch trade videos just to learn more. Currently we need more people that are into the trades. The kids we get now are only in it for the money. I had one kid tell me he doesn’t get paid to watch videos.
@@victorsr6708 Thanks man I think one of the last things a person can do is pass along your knowledge. When I got out of college I thought I would never step into a classroom again, today I do nothing but try to keep up things are always changing. Ron
Andre sorry for being late I just saw your question. The offset bend allows the conduit to hot the hole on the side of the box which is not flush with the back of the box. Hope that helps Ron
This is fantastic. I'm a DIY guy attempting to run conduit in my basement. This will allow me to make a semi-professional looking installation.
Glad I could help have fun Ron
Watching some people explain things was like watching paint dry compared to this video, very upbeat and helpful!
Hey Leonid I appreciate that! I'd like to think I don't bore people..........except for the wife. Thanks for review Ron.
I’m in the field bending conduit 2 months into apprenticeship they had me bending first week. Everyone here bends the bend and puts the conduit up then marks and cuts it to length that’s how everyone has shown me if there is a different way I hope I can learn it eventually
It is probably faster doing it that way. So not a bad idea have fun Ron
Thank you Ron! I recently got my electrical certification and then hired by and electrical contractor. I had no idea how to bend conduit, but your explanation clicked perfect in my brain lol! Now I'm the go to guy for bending on the job. Thanks again man!
Hey thanks so much really good to hear have fun Ron
Thank you for this video. As an apprentice I kept being told to eye it and it wasn't working out for me.
Watched this last night and my first offset today came out perfect. My journeyman appreciated it!
Cool glad to be of help good luck Ron
As an apprentice thank you for this! I'm not too good at doing things by eyeballing and thats the only way people have been teaching me. No one knew what the marks or shrink or anything was so i was pretty confused on what exactly was going on. Now that i know the right numbers i can practice this alot easier and hopefully get the muscle memory to do it without the marks. Thanks for the video!
Hey man you just made my day! Glad you could use the info. Ron
I am a apprentice right now and Everything you said I have went through the last two weeks. “Just eye ball it” very hard to do when your new. Ron’s videos are definitely making me more confident!
I’ve been doing electrical for 10 years now and I’m always measuring to bend any offsets,90*, or box offsets. I like having my work look clean and professional. So when I see an apprentice not measuring or using their level when bending conduit I always correct them to do it the right way and not eyeballing
@mlopez7315 dude can you tell my jmen to do the same thing? Dudes the same as others "learn how to use eye ball" dude needs glasses to read and telling me to eyeball lol
@@jaysmokey123😂
1st year apprentice out of Local 606 in Florida. This was a great video to cement box offsets in my head. First conduit bending practical tomorrow. Thank you so much!
Hi Alex comments like yours are why we do these videos. Stay at it you will do well Ron
On the job, watching your video as I bend the conduit. Man, I love these types of videos.
Hi Ed yep they are good reminders especially if you don't do much conduit bending. Thanks for watching Ron
Ron Kipper Datacomm I
Hey
Thanks for the info. After pricing out all the little fittings to do a large (for me) project in my basement, I figured it would be cheaper to just buy a bender. Too bad it didn't come with instructions. I'm going to be making about 16 offset bends like you just demonstrated and this was exactly what I needed.
I'm glad you mentioned how to tell when you are at the proper degree... I hear a lot of arguing over whether you bend until the pipe is parallel with the line or until the side of the pipe touches the end of the line... I am impressed you answer every comment... I would like to add that the 10 degree bend is achieved when you take the spring out of the conduit doing a floor bend... When you put a conduit in your bender the flatback hook creates a small gap between the conduit and the floor, creating that little bit of spring. A 10 degree bend is when you take out that spring and the conduit lays flat on the floor... Still, good video for those who haven't been bending for the past 40+ years...Keep it up
Hi William thanks for the comments and tips. I need to make another video with tips on using the bender as I have gotten a few from guys like you. Seems there is always something new to learn. Take care Ron
When I was in HVAC/R trade school the first part of the course work was all electrical....to the point where we had to bend emt that had to fit the instructors template. I wished I had remembered how to do all that
Yes i agree bending conduit takes lots of practice I made the video but certainly don't consider myself a pro. Have fun Ron
this is a very useful video for beginners, unfortunately when I started I didn’t have such instructions, I learned from experience by eye I feel how much is needed
Cool glad to be of help have fun Ron
Great video. I do industrial and commercial CCTV installations (mainly outdoors), I install EMT extensively for work, this video is helpful even for someone with experience doing EMT bends. Thanks.
Hey thanks for being out there I appreciate it!
Ron
I retired after forty years in the trade and over the first years everything was in pipe but eventually it boiled down to mechanical rooms in pipe for the majority of work and bx for the rest. In all honesty I've never seen many electricians do much math beyond 30 or 15 degree bends. For most benders 30 degrees is a two time multiplier and it's simple for most people to remember. Measured bends we typically did on the floor ( if you're lucky the bender has 30 degrees with a straight up handle) and estimated bends we do by eye with the bender upside down. For non exposed pipe work we simply put the pipe in and pull it down and flip it over and reverse bend it to be close and if it's bit too deep we roll the offset to fit. Not that we can't do it exactly or don't know how but on most jobs speed is just as important as anything in keeping your job. If you have to pull out the ruler and pencil for every bend it will take twice as long to do. It is important to know how though when you're working with hydraulic benders and large pipe sizes. I did a mechanical room for a new downtown jail in houston and had rows of pipes on racks up to four inches stacked on top of each other all going into multiple pieces of switchgear and it all pretty much had to match and be exact to look professional. I even took pictures when completed to remind myself that I could do fine craftmanship when needed. Get to know your bender as much if not more than your multipliers. And for a service electrician you should be able to bend rigid for underground by bending on equipment, truck tires, or even trees to fit the trench layout when a bender isn't available. You should also be able to reverse bend using a straight edge when a protractor isn't available so you don't even need to know the degree of your bends but only the offset dimensions.
Wow sounds like you know your bending appreciate the feedback Ron
This is the most "ideal" video about conduit bending.
Hey man appreciate it! Ron
Wow, you just leaned that thing right down! I just did it with 10-foot 3/4 EMT inch conduit (I don't think the length makes much of a difference, but maybe the thickness does), and my armpit and chest near my armpit are in a good deal of pain! My hat is off to you, thou true specimen of a man!
Hey you should try bending rigid! It is a lot harder have fun Ron
@@RonKipperDatacomm1 I'm going to tell my mom you just laughed at me. I'm millennial and don't have to put up with this! :-P Oh yes, having fun. Got a nice-looking conduit going into a box mounted on the wall. Thanks for the instructions! Now time to go cut out some cardboard so I don't hurt myself again...
On my Ideal rubber boot I placed a Stainless Steel Worm/Hose Clamp (the kind where you turn the screw head and it tightens) round the shaft part of the boot and tightened it. It stops the boot from turning and/or coming off.
Hey James usually that boot is not that loose but if it works it works have fun Ron
I'm currently enrolled for an electrician course and enjoy your videos
Hi Aldo thanks for taking the time to watch the videos! Ron
First day by myself as electrician specialized in alarm systems tomorrow (canada), thank you so much. I gotta do 2 conduits tomorrow. Easy bend path but haven't bend pipes in 3+ years
Hey I know the feeling if you don't bend conduit everyday you lose it quickly! Ron
Thanks for posting. I admit not reading all the comments below, so please forgive me for repeating if was said before. There is a tool (press) that makes the bend with one movement. I have the ones for 1/2 and 3/4 EMT. There maybe more for other sizes.
Hi Hashem yes that has been brought up before. I think they are around $150-200 if you work with conduit everyday I could see buying one. Have fun Ron
@@RonKipperDatacomm1Thanks for the reply. I did not pay that much when I bought it. But that was almost 40 years ago! I am retired now and may sell them.
Hey Hashem I have a shop of tools I use just once in a while............thanks for watching Ron
That offset has dog leg!! An there's not level!!! Really??
In most jobsites I've been in, Ideal is the most common hand bender I've seen so far. Everyone develops a favorite brand of tool, and I think I'll go with Ideal. It would be nice to get a good feel with this, as it is the most common one thus far.
juak91 box offset are really pretty esasy a little practice and you will have it down. Have fun Ron
This was exactly what I was looking for. This was a better explanation than the other guys videos. Subbed.
Use it well Ron
I learned from this video before I ran EMT for the first time when I added a circuit to my basement. It came out great. But- when I need a box offset at both ends, I get completely confused on which side to start the bend on the second end. A couple times I made the offset in the opposite direction from what I intended; ruining the piece of conduit. What’s a good way to make sure you do the second offset in the right direction?
Hello just turn the conduit around and make the same bend on the opposite side of the conduit hope that helps Ron
@@RonKipperDatacomm1Hey thanks. Yeah after I thought more about it, it made sense to start the bending the exact same way I started the first one. This time I marked the “top” side of the EMT on both ends so I knew which side is up when starting the bend on the second end. That also allowed me to make that mark in the center so as to avoid the dog leg. I am adding a circuit in my garage and the conduit came out perfectly. Thank you.
Been years since I've done this and forgot...ON THE JOB! Saved my rear Ron, thanks!
Hey Tits I know the feeling I don't do a lot of conduit bending either. Have fun Ron
Freeze-frame at 3:42 is captioned "Bottom of conduit even with 10 degree mark". This image shows a large gap between the bottom of the conduit and the mark above 10. Should the bend be continued until the conduit is even with the line above 10?
Hey Bill I see your point but I believe it is the angle I took that picture that kind of throws off the view of the mark even with the bottom of the conduit. Good catch it seems like about ever video I have every made can be done better.......Ron
Thanks for your response. Not trying to be picky, just want to learn the technique. After several attempts I developed a different understanding of the angle marks. My results seem to be better when I bend until the tubing was parallel to the angle mark as shown in the 3:42 image. (Imagine extending the 10 degree mark until it is as long as the portion conduit on the right side of this image. The conduit and the extended mark should not intersect.) When I tried bending the tubing until the bottom reached the mark, the offset exceeded my requirement.
Bill bending conduit is all about practice I am sure you will get the hang of it. Not much new in bender head design in a lot of years now. Maybe a beeping noise when you reach the mark???? Ron
Why is the first Mark 2 1/2 inches? And how do you come up with that number? Well I know you said the first mark is so that it will fit into the box correctly, but where does 2 1/2” come from?
Hey Beau the first mark could be anywhere between say 1-3 inches if you wanted and 2 1/2 is just a good number and makes a clean looking bend. have fun Ron
Beau Ferchaud I might beat you up later
Great video instruction! What is the multiplier for the 3/4" EMT, is it same as the 1/2" EMT? Thanks much!
Yes same multiplier Ron
I have been looking all over you tube to find some one to explain the box offset. There are many videos showing how to do more complicated offsets but I was just looking for the most basic. Thank you for the video. I tried using 30 and even 45 degree offset logic and it never worked. Never thought to use 10 degree. Thank you!!
+Joseph Dafo Hi Joseph nice to hear you found the channel and thanks for you input. I do appreciate it. Ron
another way is soon as you feel the pipe bend stop and rotate and do the same
if you are new to bending pipe, you can also use a 4 square box to see if you have to much or not enough offset
Thanks for this video. I am a first year apprentice and this really helped.
Hey TW use the info well you are in a good industry!
BINGO! You taught me something I never knew, real fast! Thanks!
Cool glad you can use the info have fun Ron
I have a 1-3/4 offset timed it by 6 which is 10.5”. Made my marks, did the bends at 10 degree and the offset is way off after bending. Did it twice and both wrong. Not sure why my offset isn’t coming out correctly.
Hello I am not sure what you are doing wrong have you seen this video? th-cam.com/video/5rNrEak1K9o/w-d-xo.html I hope it helps Ron
Been using the 1/2 offset fittings for boxes but the 3/4 size doesn't seem to allow the 3/4 conduit to sit flush on the wall. Do I need a special box for these to work as it seems the conduit never wants to sit flat with the wall with the 3/4" offset.
Greg just bend the offset for the 3/4" conduit just like I did for the 1/2". Pretty much the same bend but using the 3/4" bender. Have fun Ron
My bender is old and doesn't have 10 degree mark. What is your suggestion besides buying new bender.
If it does not have a mark test bend a conduit it bend it once you get the right angle make a mark on the bender, Best I can think of good luck Ron
@@RonKipperDatacomm1 Thank you very much for the info. I'm using out dated tools but they still do the job. Never noticed this missing indicator mark until I watch your video. This bender was given to me 40 years ago lol. Time flies when yur havin fun.
So is it 1/48 of an inch of shrinkage for this bend lol?
Should it even be taken into consideration?
Yes the shrink is not worth worring about. Ron
@@RonKipperDatacomm1 thank you sir
Love it! Thank you! I am very loyal to Ideal products as I've grown up in Sycamore!
Hey Frank2398 good to hear from you! Sycamore is a nice little town still but has changed alot in the 29 years I have worked for IDEAL. Have fun Ron
great video. but why is the first bend/mark at 2 1/2, and will that first mark work for a 3/4 pipe EMT ?
thanks.
+Humberto Godoy Rodriguez The first mark at 2 1/2" was just a starting point I chose it could be closer to the end of the conduit if you wanted. Ron
How did you come up with a multiplayer of 6?
THANK YOU! This was great. I watched the Lowe's video on offset bends and the kid literally ruined the EMT and then moved on like nothing happened. He even made the first bend 25+ degrees, "called it ten" and then continued the tutorial lol
Burr Yes I have seen that video and even sent them an email. Thanks for the feedback I just watched the video and ought to edit it to about 2-3 minutes........Ron
Thanks for that just looked it up it was freakin hilarious!!
Don’t talk about Cory like that😂
I always do it by feel but sometimes I doesn't work perfectly I think im just going to start measuring and doing 10 degrees now
Yes I think most electricians with some experience can make this bend without making any measurements. Just take practice have fun Ron
2.25 is what I was looking for, thank you
OK glad to help Ron
About to start a job out on a solar farm and I am getting hired as conduit bender and wire runner so I gotta brush up on my basics! thanks so much for explaining this.. My bending has gotten rusty! I use to make dog legs all the time...
+Ted Raney Ted I said the same thing when I started making the videos! Bending conduit is not hard but takes a little practice. Good Luck on the job. Ron
I come here for the comments. Because electricians are grumpy and hilarious all at once. But seriously, thanks for the video. Good work.
Hi Laura thanks for the comment Ron
Great explanation. usually I hate too much explanation, just do it, but then I'd be asking too many questions and wasting time. i Like, OLE!
Hey thanks for being out there Ron
Where would you find the maximum number of degrees allowed in a single bend?
Total amount in a conduit run should be 360 degrees I believe. It should be somewhere in the NEC I am not sure where though. Ron
@@RonKipperDatacomm1 Yes, we already know that part, but I can't imagine why anyone would do a 360° bend.
That is a total of 360 degrees which could be 4 90 degree bends along the length of the run. They are not making a circle...hope that helps Ron
Thumbs up.
I've never bent an offset in the air nor marked for one. My 1/2" Gardner No.930 doesn't have the angle marks, it doesn't even have a star.
Hi GrimmGhost most people who have done this a few times probably won't mark the conduit like I say in the beginning most people will have this bent before you know it. Have fun Ron
Well, I have to admit I feel stupid for not realizing how easy it would be to make this type of thing precise. I've bent conduit before but you really explained it well. I work in the RF industry, so we run lots of coax and data cabling. Customers are always wanting us to install conduit for them, but we always have to farm it out to an electrician. I think I can probably do this though! Most of the runs we have wouldn't be much more complicated than this vid.
+uncleben03 Really it is mostly a little practice and experience with bending conduit. Glad it helped you out and don't turn down the work next time. There are 7 videos in that series so good luck. Ron
Don’t steal their work.
@@marksanchez253 Bending EMT IS NOT just electrical work.It is used in many trades,
Why do all the video use 1/2 inch Conduit?? Where do we find 3/4 EMT videos?
Hi Bubba 3/4" conduit the process is the same. I used 1/2" because that was the size of the benders that I had when I made the videos hope that helps Ron not to mention 1/2 is easier to bend!
Great job, Ron. You still got it. Don't show this to the ladies or you'll be beatin' em of with a stick!
Hey Bradley thanks for being out there. Ron
You measured for a box offset? Whoa. I never even knew you could do that. Guess it makes obvious sense, I just never had reason to try
Yes but like I say in the video most guys just bend it without measuring it have fun Ron
From Panama City for the great teacher Ron from Alex you are an exelent Instructor
Thanks you sir! I appreciate you watching. Ron
You are a great teacher. I did what you said and of course it worked perfectly. Thanks for sharing your knowledge.

Sure thing. Send to: sfogle2894@gmail.com
How does he know how far back to make the 1st mark?
Mike you want to make the first mark far enough back so the hook of the bender is not on the very end of the conduit which I mention in the video. Ron
What good is this video for PVC conduit?
Robert none if you are using PVC just used the proper fitting for the box. There are PVC electric blankets you can buy if you have an odd bend you need to make. Ron
thanks for the tip. I'm starting to bend tomorrow. I have little or no experience but I have been practicing.
+dvdlzo1975 Good luck on the new job. Ron

Thank you Ron , thank you I was goin nuts
Glad you can use it. Ron
Great video! Short and to the point!
Hi Mark use the info well. Ron
Are you kidding? I used it the same day to make a two out-of-plane bends in the same piece! Great!
Thank you for the info, but the marker is to count because when the pipes are exposed you see the marker it looks ugly so you have to use the pencil.
Hi Michael I mention normally you would use a pencil and a lot of people probably won't matk the conduit at all because they have done so many offsets it is a pretty easy bend to make. Ron
Hello Ron, Great demo I learned a lot. When you had the 3/8" where do you measure from to get that distance? Back of box to edge or back of box to center of the knock out? My practice pieces are not coming out right, I suppose a lot of practice does the trick.
Hey Dana the 3/8" is the height of the obstruction or the opening of the knockout on the box. It is used to figure the distance between the marks you will make. Yes practice goes a long way. I know when someone asks me some thing and I have not bent any conduit for some time I have to think about what the answer should be. Good luck Ron
Suppose you had a connector and a straight piece of conduit going into the box knockout. 3/8" is the space between the conduit and the wall, this is because the hole isn't flush to the wall.
How you get 2 1/2 like what math did you use to get that mark
You could make that first mark at around 2 to 21/2 in. and is just what I use to keep the bender head from damaging the end of the conduit. No math involved Ron
I do my offset bends on the ground, like the rest of my bends. I'm a skinny guy, when my boss taught me, he taught me to air bend for precision offsets. I would always bend in jerky inaccurate motions trying to air bend. But on the sly I did a bend on the floor. Right on the money. Been doing it since. one of my coworkers thought I was a freak of nature because I could bend offsets and saddles on the floor.
As long as they come out right! Thanks for the comment. Ron
UrvineSpiegel but do you do the bends in reverse order from how Ron demonstrated? Otherwise your 1st bend would have pressure from the floor and distort?
Excellent Video Brother
Apprciate it! Ron
How do you come up with the 10 degree number?
Rod 10 degrees is the smallest degree mark on the bender head and about all that is needed to make the box offset bend. Plus it is easy to pull wires through it to. Hope that answers the question. Ron
Yes, but how do you know you need to bend it 10 degrees as opposed to lets say 15 or 20 degrees? What is the method used to determine the number of degrees to bend the conduit.
Hey Rod 10 degrees is the smallest graduated mark on the bender head and there is no mark for 15 or 20 degrees. Plus the smaller the angle the easier it is to pull wires through the conduit. For a slight offset like this box offset the guys in the field have always used 10 degrees. Or I could just tell you what my Dad would of said "just do it because I told you to!" Take care Ron
I think we are missing something. I understand that for a 3/8 offset the degree used is 10. What if you have a larger obstacle to get over, like a large pipe, then how do you determine the angle to use. Is there a method to determining proper angles for different obstacles?
Rod for most obstructions that are 5-6 inches tall or less a 22 1/2 degree bend works pretty good and taller that that a 30 degree offset seems to work out better. There is no set rule I know off other than try to keep the amount of bends down so it is easier to pull wires through the conduit. I believe the NEC states there should be no more than 360 degrees of bend in a single conduit run. Hope that helped Ron
Best ❤Conduit to box offset .
Thanks use it well Ron
Works every time....ty
Cool man! Ron
how did you figure out distance between bends
The multiplier for 10° bends is 6 times the 3/8" offset between the knockout and the back of the box is 2 1/4". Which is the distance between bends. Good luck Ron
Very well explained. Liked and subscribed 👍🏼
Thanks have fun Ron
Great video, thanks for posting Ron.
Glad to help take care Ron
Thanks man this helped a lot
You are welcome have fun Ron
Thanks for the ideas you have discussed here.
Good to hear from you that video has become one of my most watched videos per month, I looked at your channel you have a start on making a nice channel. Good luck. Ron
Fantastic video, thank you
Thanks Ron
Excellent explanation
Hey Victor thanks for being out there Ron
I started bending 1/2" EMT in my electrical class and it has been kicking my butt. Hopefully this video will help me out, thank you sir.
+Mejia Cool hope it helps you too. A little practice goes a long way. Ron
Best thing I ever did when I was in school was hang on the back deck with a 12 pack. 100ft of emt and the uglys book. Ever since that day I fly through pipe work
Why do we need to offset the conduit ?
I explain that in the beginning of the video. The knockout on the box is not flush with the back of the box and a slight offset in the conduit cures the problem. This way everything can be clamped down without putting pressure on the conduit or box. Ron

Hi Luis sorry for the delay use it well Ron
EXCELLENT VIDEO, THANKS.
Appreciate you watching Ron
The multiplier for a 10 degree bend is 5.76 NOT 6 as it is stated in the video and yes the difference matters.
For an example lets do the math for a 5 inch offset with 10 degree bends. Using 6 (the multiplier you are using) the spacing between bends would be 6 times 5=30 inches NOW using the PROPER math lets do the same offset 5.76 times 5 =28.8 which using the standard rounding method used by electricians would be 28 and 13/16 inches . That is a difference of over an 1 inch or 1 and 3/16 inches to be exact added the spacing between bends using 6 instead of 5.76 and that makes a huge difference
+chris sanders Chris I should put a disclaimer in the video that I don't know everything..........thanks for the tip and I may reshoot the video or add an annotation with your comment. Appreciate the heads up and you taking the time to sent me a note. Ron
Thanks for sharing this. Very helpful.
thanks for that! I just bought the ideal 1/2" bender earlier today. Menard's didn't have the iron one... and I do electrical work so infrequently that I could not really justify the extra money anyway. I'd never used one before and my electrical box offset for the starting point is pretty embarrassing looking. :( I did do a good 90degree on my own.... wasn't at the right point where I was thinking it would have been but I didnt need to be exact (thank goodness).
Hi Bill glad to be of help. That aluminum head bender should last you many years. Use it well. Ron
Ron, would you be able to help? I have to run about 200' of conduit in a strip mall through 2 other suites along a back cinder block wall. I am nervous about the offsets. I am not sure where to measure (i think I do have it correct in my head when it comes to bending one side, then doing a 180 on it and bending the other).
For going into the next suite, if I drill at the back corner of the wall I think I will hit a lot of obstructions. I think it would be best if I went away from the wall a few inches, then back flush against the wall in the next suite.
I am just sure how to measure or where to place my measures and at what points to bend. :(
Bill I am not sure I quite understand what you are trying to do. To measure the offsets just measure the distance between the box and the last conduit fitting. The bend the offset the shrink amount is pretty small about 1/16" so it should not be a problem. Keep in mind the NEC recommends no more than 360 degrees of bends in the conduit run. In many cases practice is the only way to learn so you might waste a couple sticks of conduit working it out. Good luck. Ron
Ron Kipper Datacomm To clarify that 360 degrees of bends in the conduit run. If there is a junction box or pull box in the run, can you then have more degrees of bend?
Correct, 360 required between pull points
i seem to keep over bending my 1/2 inch conduit! so annoying haha
Hey John a little practice and you'll be a pro at bending conduit. Ron
Its probably cuz you are so strong 🤣😂
Thanks for explaining this offset bend! I always do it by eye and usually over bend or it turns out crooked. I
+Progrocker70 Thanks for watching and have a good night! Ron
Great video !! I'm in the HVAC field. I currently use B/X for most of my work but I think it looks sloppy. Always wanted to utilize conduit and I believe I will. Thanks
+HVAC DOC. Good to hear from you!
@@RonKipperDatacomm1 Should Flexible Metallic Conduit be the choice instead of LMT for situation where a motor can cause vibration and loosen the connection in the long run>
And if it is connected to the A/C unit outdoor, should the choice perhaps be liquid tight flexible metallic conduit?
@@ang6774 flex should always be used with equipment (including transformers) that can vibrate. Just change to flex ahead of connecting conduit. Outside should always be liquidtight, inside depends on the environment. If it’s a area exposed to wash downs like a commercial kitchen for example use liquidtight. And explosion requirements utilize a special flex and fittings. Always pull a grounding conductor with any flex.
@@ang6774 yes! Also pull a grounding conductor with any flex.
AMAZING TEACHER
Hey Angel thanks for being out there! Have fun Ron
THANK YOU I ALWAYS WANTED TO KNOW HOW TO DO THIS
Hey james thanks for being out there. Ron
Thanks amigo for this video it helped me a lot!!!! I appreciate it
Hi Juan thanks for watching. Ron
Ron Kipper Datacomm thanks bro it helped are u a master electrician i want to learn more so that's why Iam watching your videos
Nope would never claim to be an electrician but do have an engineering degree and about 35 years in the industry. I would like to think I have learned something along the way to pass along. Thanks for being out there. Ron
awesome presentation very informative and articulate.
Thank you sir! Ron
Good video,I like to run conduit.But out of work right now in the Southern West Virginia area (Mercer county).Have my own benders.
Hi Mr Howell thanks for the comment on good luck with your job search. Ron
***** I got my own Benders 1/2 to 1".I thought about makin' a video similar,glad I didn't.There seems to be alot on TH-cam.I plan on running 1/2" conduit in my garage in few /months.Good video,& you are welcome.
OK yep there are a few videos out there on bending conduit. Since IDEAL has been selling them for over 50 years thought I would create a few videos.
awesome video ron!
Thanks for watching! Ron
Good teachin’ Ron!
Hi Bill appreciate you watching the channel! Ron
What do you mean electricians don't cut conduit? How do you fit a 10 ft piece of conduit when you only need let say 8 ft total EMT length?
cruz47144 he says bend than cut it, obviously you cut it, but you should know what length you need to cut before bending is what he meant.
He means after bending, ideally it should be the correct length after bending, when you are new at this you leave a little extra length to allow for error correction.
also all you got to do is remark your mark with the Sharpie and rub it off. abracadabra poof gone
Carter Hamilton awesome that is the trick I learned fabbing sheet metal many years ago
Great job 👏🏽
Hey man thanks for watching! Ron
2:09 How it's done.
Have fun man Ron
Thank you ideals
Hey Pat I appreciate you watching the channel have fun out there Ron
