In today's episode of AccessToPower we will wire up a forward reversing starter. We will show how the mechanical and electrical interlocking works and how to do a proper forward and reversing starter in order to keep personnel and equipment safe. There are many different ways to achieve a forward and reversing starter setup. This is one of those methods.

dude this is amazing, thank you so much. having an ACTUAL MOTOR is going next freaking level. thank you.
Thank you. I appreciate the comment.
I am binge watching your videos lol. Refreshing on everything and you are a tremendous teacher. Thank you.
Wow. If only every Jman could explain topics like you do. Break it down wonderfully and kept it simple. Love the schematic drawing on the side that highlights what's live and what is not. I'm sure that will help with more complicated wiring.
Give this man a raise. You have simplified this way better than the computer learning we are currently doing. I commend you for all the work you do and all the help you have given us.
Thank you!
Thanks to your video I passed my mine electrician test, and be making almost 60/hr 😎
Congratulations.
Very well explanation thanks for not being in a hurry like the last guy!!!
This is great and much appreciated. Refreshing my memory for garage door openers and this is exactly what I need to see. You explain everything very clearly. The wiring diagram on the side is PERFECT. It crosses the bridge between the paper and real world application.
This is a pretty comprehensive and well done video, thank you!
You are the best teacher ever!!
Thank you for the very clear demonstration.
Within the first 2 mts I liked your lecture, I can't wait until I finish the video to subscribe. You are the man.
Thanks! Means a lot
this is incredible with the diagram in the corner. in most video's you just see people connecting stuff but you dont know what the contactor is labeled or what terminal they are putting it in.
I have installed and wired pretty much every device in industrial construction in the field, but sadly not even once have i had the opportunity to actually wire any contactor, relay, or any control related device.
Thanks mate absolutely love watching your vids. Keep up the great work👍

James. Thanks for commenting on our video, and welcome from Brisbane!
Thank you very very much. It is very helpful.
Yeah, this was great man thanks for the refresh.
Very impressive sir, I was wondering what would happen if you turn on the reverse button while the forward started was on, but you just did it right away.
Very cool presentation.
Thanks for sharing.
Thanks you so much for your videos! I'm currently going to college to get my elec. Certification and they really helped alot. Much appreciated man.
Noel, I am glad the videos helped you through your college classes. Thanks for letting me know they helped you. It encouraging!
Thanks for the videos!
I keep watching, so when the time arises I will be ready
Thanks Walter I always watch your video
Thank you, thank you, thank you ! I finally understand how to set it up
Good teacher ,I like his lessons
Love your videos.
these videos are priceless
Many thanks for wonderful information
This video is so good! Thank you!
I love your videos man!
enriching video presentation, please will like to learn more on electrical controls from you
Great work on teaching us, you are meticulous on how to explain functionality, thank you for doing that I understand more from your videos which I greatly appreciate thank you Sir
Thanks for your positive thoughts and comments! I appreciate it!
Thanks for your sharing it with us. This is a great tutorial and very informative...

Your videos are awesome I'm going to school for a associate's of applied science in industrial technology and your lessons are exactly what I'm learning in motor controls
Thanks Matthew for the comment. I am glad you are finding the content here helpful. Much success in your studies!
@@AccessToPower I need to sharpen my ladder diagram skills far as labeling could you post a video on that please mainly what should be labeled and a clean readable way to label thank you so much
Amazing video
Que bien lo explica., gracias!!
Very nice thanks
Access electric by far the best hooray hooray for Access electric
Excellent nice presentation i learn more about your channel teach more im just a begginer
Good job
Thank you these videos helped me so much.... bad **s
So amazing
thank you so much
Nice presentation sir
Good morning - thank for sharing your knowledge. Please share part number for switches that you're using in the video. Thank you Sir.
I always teach to only swap A & C phase to reverse the phase rotation. This prevents accidentally burning stuff up in the rare time one may have to deal with the high leg on a 120/240 3 phase feed. (Code here is the high leg must be on B Phase)
That is a good idea. Especially if the control voltage is 240 volt delta. But it is a good practice to teach newbies as it eliminates possibly making a mistake when the voltage, or high leg information is not understood or known. And yes, High Leg is most often on B Phase in the field... but there are some utilities that provide the high leg on C phase and it must be switched after the MSB to B phase on all Panelboards, and MCC's. This too can be a bit confusing and cause people to make mistakes. Thanks for your comments and sharing your best practices with the community.
you are a very good teacher thank you very much. would you please tell me the simulator name and where we can find it ?
Would like to see that done for a single phase motor .
Is there a schematic for this somewhere? This is very useful
Could you add the terminal numbers? 13/14, 95/96? as example. I have found that this helps students keep track from the drawings to the components. No complaint just a suggestion. Great videos, well done and easy for folks to follow. I like how you split screen to show component and drawing simultaneously.
Can you do a video of a VFD with a remote switch control with an E-stop and, an of/on switch, a forward/reverse, and a potentiometer all to be used in a milling machine. The drum switch currently on the machine reverses almost instantly (needed when tapping); it is not necessary to stop the motor and then energize the reverse switch.
Nice in depth explanation video. I'm looking for info just like this. I am looking to wire up something like this for my cargo lift in my garage, three phase worm gear drive motor system. Looking to have EMO, up and down fixed on second floor and the same for first floor. Also looking to have one on the platform wall so when I'm riding it. Would the switches need to be three way.
Nice! This could work, but you also may want to add limit switches for the “at top” and “at bottom” locations which break the holding circuit as well. This will ensure the lift stops when it reaches your desired location. For Saftey purposes you may also add 2 additional limit switches for over travel which are tied into your Emergency Stop circuit. This is to protect you in case the normal limit switches malfunction and the lift doesn’t stop where it is supposed to, the over travel switch’s will trigger the Emergency Stop.
Superb ❤
Thanks for liking
Would you be able to provide a parts list with PN's on what you used for this video. Thank you.
Good videos. However. those devices are not starters. they are contactors. A starter is a contactor plus and overload relay. When you added the overload relay, they became a starter.
Hello sir thank you for everything how can I get all the components can you please send me the whole description of everything
Very Helpful Video! But could you make a video on Wye-Delta Motor Control Circuit with Forward and Reverse, Please!
Star/delta
Hello good video can you give the the list the parts you used I have project the same you do I’m confused 🤷♀️ thanks if can help
What kind of program do you use for the ladder diagram?
Nice video but I think it's way easier to have 1-0-2 switch so you can't mix direction and it's really simple.
I think this could be useful in bigger machines but then it's better to add PLC
And I'm all about safety and working with live wires is not my thing.
Like video
How does this work for a 130 vdc, 25 amp dc motor? I’d like a forward, stop, reverse buttons for this but I don’t know what I need or how to wire it. I’m using a 4.25 hp Leili treadmill motor.
Thanks,
Paul
Hello, I have wired my 3 phase motor per your video and used same components best to my knoledge, the issue I'm having is when I turn on my 120v brkr it pops. I looked over everything a phew times and can't see what's wrong. Any ideas.
Thank you for your time.
I was wondering if you could do an updated video but more zoomed in to the motor starter to see the termination labels? Thanks
I actually just filmed a new forward/reverse video and it should be done editing today. I will release the video on Tuesday next week.
Thanks for your comments!
@@AccessToPower My pleasure, your videos are very informative!
I wish you would provide links to purchase all of these components so that I could build my own set.
He is using products made by Eaton just google them and many electrical retailers sell them
HI Walter, what state do you live in? Offer any classes? Great presentation, would be nice if you can do a close up with interlock for the forward and reverse please
Young Pam we are in California. We currently offer classes to our employees but have just begun construction on what we hope will be a vocational training center
@@AccessToPower hello walter, which city in California? I hope your vocational classes is offer to outsiders and not just your employees, which I hope to joined in prospective.
I was wondering if you wanted to wire a indicator light when either starter is pulled in how you would do that in this situation?
good question. stay tuned ... in the next few videos we will add sequential starting. indicator lights on run and on fault, as well as timed start....
Do you give a hands on Training?
I think I would need to physically wire all of that myself to fully grasp the concept.
That is why being a adult and having money you can go buy this equipment and learn it at home or at work or business.
Can you tell us the name of the simulation software you used
How do you connect a110 volt where it’s 4 wire to the Motor
Can someone please tell me the software he is using for the simulations.
This system seems as if it would make a great dumb waiter set-up, how would you incorporate limit switches into this system? Fyi you have awesome teaching skills, very informative without going over doing it. Lmk thanks
Tony Ciarleglio
This would work for a dumb waiter setup with the addition of 2 Normally Closed limit switches. If forward is up then I would place the top limit switch in line just before or after the existing NC “R” contact on the rung that powers the forward starter. When the waiter gets to the top the forward starter would loose power as the limit opens. You could then add a bottom NC limit just before the reverse starter coil to stop the waiter when it reached the bottom.
Thanks you're the best!
did you do the control circuit wiring simulation on some kind of software, if so what is it?
thanks a lot btw.
It’s called Constructor by CMHSoftware.com
@@AccessToPower thanks
I have an old conveyor belt and it has a similar circuit to this BUT if the motor is spinning clockwise and you push the momentary switch to engage the counter clockwise position it auto cancels the other contactor and engages the other contactor. Do you have a video that explains this wiring?
It sounds like you are missing the normally closed electrical interlocks.
Grumman, I looked a bit more at your question and what is different about your forward/reversing setup is that your interlocks are not being controlled by a normally closed contact from the starters, but by normally closed contacts on the buttons. I am creating a video right now with the schematic on what is different and how to wire it. Thanks for the comment. I will send you a link to the new video when it is uploaded.
Sir you or your company sell a software or Cd that I can download to my computer so I can study while I'm on the ship. Thanks
Note: they a contactors (relays) not starters.
Please tell me the difference between a starter and a contactor
@@kyliejoe91 The only difference between a contactor and a starter is that there is an overload relay connected in series in line with the controlling contactor. This overload relay is what protects the motor from burn out if something goes wrong with the mechanical load such as a conveyor belt jamming or a bearing seizure. Some starters even have a phase loss feature which shuts off the motor if one of the phases is lost due to a storm for instance. This will also prevent motor burn out due to single phasing.

This video is good but it would have been a whole lot better if he broke down where the wires are attached from and where they are coming from such as when he was installing the wires for the hold button so they will not be operating like a momentary button. He should also show the pieces and model numbers on the screen. But he should’ve broke down where each wire was coming from and where it’s going and zoomed in so people could see it. I would say he should remake this video and be more in detail.
Nice video But Demonstrating Proper PPE around live wires is also educational to others Due to arc fault and your NFPA 70e standards
Wheres your PPE
Don't you have change AB or BC to change direction? Changing AC will do nothing.
irwin jimenez , changing any 2 will reverse direction
Sir your videos very nice but you talking English Indian people need Hindi I love you working ❤️
Me confused 🙈
Where is mechanical interlock?
Lorch Service, I install it at the 1 minute mark and explain what it is.
You still need some electrical knowledge to understand this video. I know almost nothing and get lost after he adds the bridges. More detail on components is needed.
This isn't the right way to do a forward/reverse motor controls it does not meet IEEE standards of manufacturing nor it meets electrical trade industry requirement, further more it will be difficult to troubleshoot in case of failure.
-line protection this is exactly how its supposed to be wired. All equipment I work on comes wired this way straight from the manufacturer. You're telling me they dont follow the laws?
@@scottbustos819 Yes I am telling you that they not following IEEE
@@georgenarso3148 UL seems more prevalent in the industry.
Dude you didn't explained where to wire your holding contact
F*ck it looks so complicated 😫 😕 😩 and i got a practical next week.
Superb ❤
Thanks 🤗
