In this episode of AccessToPower, we dive deep into two different wiring methods of Forward and Reversing Starters and provide you with detailed step-by-step instructions. With the help of superimposed schematics and visuals, we ensure that you grasp the concepts easily and gain a greater understanding of Forward and Reversing Controls.
Whether you're an aspiring electrician, an engineering student, or simply a curious learner, this video is designed to equip you with the knowledge you need.
Throughout the video, we superimpose detailed schematics onto the actual devices being wired, providing you with a visual aid that enhances your understanding. By presenting the information in this manner, we aim to bridge the gap between theory and practice, making it easier for you to apply the concepts in real-world scenarios.

For the purposes of the viewer you should put a piece of blue tape on the motor shaft so we can see the motor reverse directions. Great video.
Hey thanks again for the overlay of the schematic. Clarifies things greatly.
You are welcome! Glad it was helpful
Great job on explaining and showing how this all works and why. Would you be able and willing to give us the part numbers and model numbers of all the components you used in this video, except for the motor.
Great explanation on the difference between the two! Thanks!
could you tell us what is the name of the program which you have used to draw the schematic diagram???@AccessToPower
Greate video and explanations. By any chance would you be able to put out a bill of material on all the components you used in this video. I'm looking to wire my garage elevator in this manner. One switch downstairs one upstairs and one on the lift.
It makes sense and i've given a thumb up.
Thanks so much brother ❤❤
Thank you for the thumbs up. I really appreciate it.
The second method of wiring is usually found where high torque motors are used eg hoists or shutters , since they run at much slower speeds and not affected as much as high speed motors.
Really good videos thank you 🎉
Glad to see you back at it!
Thank you!
Glad to see you back. What am I missing? If the concern is the ability of the motor to be quickly reversed, what is the advantage/difference between using contactors on the starters or CB’s on the PB’s??? I’m not trying to start anything or say anything is wrong, I’m just trying to figure out how using the contactors is better than using the contact blocks.
Thank you
Using the contact blocks on the contactor will allow the motor to come to a stop before reversing. This in most cases would be the preferred method. If you want the motor to reverse immediately, then the button contacts would be the method you would choose. It all depends on how you want the system to work. Thanks for the comment!
The contactor keeps you from reversing direction while the motor is spinning and prevents damage from polarity reversing while the motor is still engaged. Using only the start/stop switches doesn’t prevent this; there’s no lockout mechanism as with the contactor. The sudden change in polarity causes heat to the windings of the motor causing unnecessary heat damage which is really the bottom line.
Industrial motors configured with Wye Delta start and run is another way they have helped extend the life of a motor and make it more efficient. It starts at a lower voltage in Wye and switches to Delta high voltage at a certain speed to help reduce heat in start up by starting in a lower voltage and then switching to high voltage at an optimal speed. It helps extend the life of the motor and make it run more efficiently as well.
That’s the purpose of the overload heaters as well; it senses excessive heat in the circuit from overloading or starting issues! A circuit breaker disconnects for a short or ground fault; a heater disengages when it senses overheating.
Just demonstrates that the breaker, starter and overload or heater all have different functions as well as the stop/start with forward and reverse controls with the contactors.
Can this be done using a breaker, two contactors, a “stop” button, and two momentary closed buttons that only close the circuit only while the button is pushed? Can a second breaker be used on the neutral in place of the overload? I’m dealing with a leeson 120v ac motor
Top-notch vids. Thank you. When are we going to see you on R - umble?
Thank you very much for a great video 👍
Your welcome. Thanks for commenting on the video.
Keep the videos coming 🤝🤝🤝
Thank you!
great video!n
It's called motor pluging foward to reverse not a problem 21:10 21:10
It's so strange when you add protection (OL) at the end (on N). Technically it works, but for service it sucks...
My ideology is: first protection, then control buttons, then contactors. And N is connected directly to contactor (A2 terminal) and it is always here.
So when you test with voltmeter, you meassure the voltage between contactors A2 and any control circuit point.
👍👍
What is simulator name ???
It’s called Constructor
Hi boss. I’ve been an electrician for around 5 years and recently landed a maintenance job at a mining site where we use vfd’s, hoa’s, forward/reverse starters, etc etc…are there any books or courses you would recommend? We have numerous types of vfds..525s, 700s, 750 something’s, etc and it’s been a real struggle trying to figure out even basic vfd functions like where to land your hand/auto. Any info helps. Thankyou sir
Here is a playlist on VFD function wiring and programming. But limited to 525’s . VFD Programming and Design
