=============================
Have you ever wondered how an automobile assembly line is controlled?
In this video, we are going to talk about what controls large or small mechanical processes like an assembly line. That device is called a control panel.
Think of a control panel like the human body. Inside our bodies, we have vital organs that control and monitor our surroundings.
Similarly, a control panel is a metal box which contains important electrical devices that control and monitor a mechanical process electrically.
Let’s get started! First let’s talk about the enclosure, the metal box that contains all of the electrical devices of the control panel.
Enclosures are often aluminum or stainless steel and the size will vary based on the size of the process.
A control panel enclosure can have multiple sections. Each section will have an access door. The size of the enclosure is commonly referred to by the number of doors the enclosure has.
Each enclosure will have an electrical safety rating designated by UL, the “Underwriters Laboratories” who governs electrical safety.
They will also have an IP rating or NEMA classification which designates the enclosure to be indoor or outdoor, waterproof or water-resistant, suitable for hazardous conditions, dustproof, or explosion proof.
Now let’s go inside the enclosure and talk about the non-electrical components that make up the control panel.
First, let’s talk about the back panel of the enclosure. The back panel is a sheet of metal that is mounted on the inside of the enclosure that allows us to drill mounting holes for different devices which leads us to our next component, DIN rails.
A DIN rail is a metal rail with a standard width used for mounting electrical devices inside.
The next component inside the control panel is wiring Duct. Ducts allow us to route the wires in an organized and efficient way while also reducing electrical noise between devices.
Next, let’s get into the electrical components of the control panel!
The main circuit breaker is where the power comes into the control panel for all of the devices. This circuit breaker generally has a disconnect on the outside of the panel that allows us to shut off the power.
Always remember the topside of the circuit breaker will still have power. The power that comes into the panel can be anywhere from 480 volts to as low as 120 volts.
After the power comes into the panel from the main circuit breaker the power will be run into a surge arrester.
A surge arrester is a device that protects all of the electrical equipment inside the control panel from electrical surges or overvoltage. An electrical surge can come from a lightning strike or utility power surge.
In this video, we talked about the components of a control panel. Each control panel will have the main power source coming in that is distributed throughout the panel to varying devices for control and monitoring.
Control panels will come in different sizes but they all have similar devices that we talked about today.

Dear RealPars, you cannot imagine how much these videos help us as amateurs in this field, so thank you guys and I hope you keep going in your amazing fabulous job.
Yeah! I'm a jr eletrician and i'm really glad for these videos! Best Regards from Brazil!
Just took my first job as an Automation Engineer with a regional electrical distributor with a focus on controls and safety. With how smart controls are getting now a days, it’s almost impossible to not know how they integrate with a PLC so these courses you put out are just unbelievably helpful in connecting the dots you otherwise would not be exposed to. Thank you for all the great lessons!
Thanks a million for your feedback! Great job on your new endeavour! We are more than happy to hear that our video courses have been so helpful.
If any questions pop up along the way, please do feel free to reach out at any time - we're more than happy to help!
Happy learning!
How do I become an automation engineer
You need to go to college and get a degree for that@@jojoessienyi7238
Could you please help me with some courses?
Sir, your narrating skill is unparalleled.. I have learned a great deal. Thank you!!!
Thanks for your support, Fabian! Great to hear that.
@@realpars Would you be kind to tell me why would an ethernet hub need 24 V to operate? isn't that a little too much? Thanks
OMG !!! I learned more from this 8 min video , than entire online plc course. Thank you guys , great job on explaining complex materials in simple way
What an amazing compliment, Alex! Thanks for sharing.
This is on point! The animation and visualization is just fantastic. So fantastic a job of visual animating and explanation, this video can literally be used just about anywhere to explain an Electrical Control Panel. A Big Hug 🤗 to RealPars! I get better at my because of RealPars and many people here all feel the same which says immensely a lot.
Many thanks for your support, Ardent!
These videos are simply amazingly well made. Thank you so much !
Thanks a lot! Great to hear that.

Thank you so much for making all this make way more sense and the way you break things down and animate it just makes it clear to understand thank you
You're very welcome, we're very happy to hear that!
Dude when something is mentioned and I’m clueless to what it is, y’all always have a video covering it completely. Love y’all’s videos.
That's amazing to hear! Thank you very much for your kind support
Thankyou - Excellent explanation and visual animation - makes it so easy to learn!
Happy to hear that, Olivia! Thanks for sharing. If you have any questions, always feel free to reach out - we are more than happy to help!
I liked this video! This is a very good basic control panel. Good introduction for people who are not into the field. For most viewers, FYI, it could get really complicated and you would have other Panels that do not have PLC's in them but have other PCB boards and other controls such as electromechanical relays, control valves, manifolds, etc, they are called sub panels. Other Sub-panels can have shunts and Servo-drives in them and so forth.
Again this video is EXCELLENT intro. Lots more to learn like connectors, and so on.
Thanks a lot for your support!
Thank you sir...u have explained every element in a lucid way....
Happy to hear that!
Best video in your channel and all automation channels on RUclips.
All your videos are amazingly helpful and educative.

Awesome sir
Our subcontractor delivered us a very sub-par control cabinet. Now I, a software engineer, am rebuilding significant parts of it to improve organization and maintainability. Also it just didn’t work because of the software, which is why I’m doing this. Thank you for all your videos I can use to make sure the replacement is clean and organized
Our pleasure! Great to hear that our video courses have been so usefull.
Superb Video on Control Panel wiring I have understood the wiring perfectly thank you for this great content 💝
