Motor Starter On-Off Push Button Station Circuit Explained

"I am not an electrician! Let me put this first and foremost, I am NOT an electrician."

*Electricians go to his site to learn about motors*

How do I know? I'm an electrician and another electrician sent me this video.

Thank you for keeping it simple! I can finally wrap my head around this concept now. This is great for visual people like me....and thanks for the drawings with different states of the circuit. Super helpful.

I need to wire in a remote start/stop on a 110v single phase motor starter. Would the wiring be any different? Your schematic confuses me as being single phase, I have no connections at L2

I’m an industrial tech apprentice going through schooling, and I understood this explanation a lot better. Awesome job thank you!

Great video simplified for beginners in control power. Thank you

Thank so much for good explanation

what model push button starter are you using Dayton 20c794?

Can anyone guide me how yo rewire up a polishing moto

Great job Mr. Rucker!

Where is your neutral? Line 2 is going through your overload straight to your coil as well as your line one

Thankfully Keith qualified his motor starter tutorial by admitting that he is not an electrician.
I quit counting the errors that he stated and demonstrated, because I quickly ran out of fingers!
On the otherhand, if you can cypher through the misuse of terminology, electrical physics and misunderstanding of overload and over current his explanation is acceptable. Follow his electrical drawings and be less generous in accepting all of his descriptive dialog. He has the functinal gyst for the novice, but he included a lot of misinformation.

Keith is obviously very accomplished. He regularly tackles work that I don't try. Kudos to Keith for getting it done, but I think that he should let this topic be handled by others that won't convey so much misinformation.

Keith, you're a fuckin G my man!

Great video. Thank you

I liked the way you teach

Another use for Motor Starter Type Switching is to protect Electronics. It shuts off the Ckt at the Hint of brown outs or Flickering Power, Like Auto reset Power line breakers and they Stay off till You deem it safe to turn them back on.
I have made a few with just an Ice Cube Continuous Duty 10 Amp relay, Nc & No buttons.
Then I plug a UPS into those if Needed.

How new is the new mechanism? I have the new one on my 20yo Grizzly table saw.

Don't forget kieth .coils have different voltage ratings .and contactors have different current ratings .👍👍

Thanks for sharing this Keith. Very well explained and simplified

Very well done. I teach this at a votech and I may use this in my class thank you

If u are not an electrician.u probably don't need to be putting this information out there. This stuff can can be kill a person. Respectfully.

Keith this was a great video. You explained everything very well. Do you have any videos on wiring up and changing voltages on a transformer.

Usually L1 L2 L 3 has 130 volts going thru them coils usually only need 24 volts and push buttons so wouldn't hooking the switch to L1 be to much or the auxiliary contact

The great thing about this channel is that I can understand every word he is saying unlike the Indian dialect videos. I am not saying the indian videos are not correct and I am not taking away from the work put forth in those videos. I just like a video that I can understand with proper english without the accent.

Great info thank you.

Hello Keith, great vid., but having trouble w/Oliver 299D planer.
It had a 400v. AB starter. I have rewired motors for 240 and bought a 509 B0D. As you know the planer has 2 motors an seperate switches for feed/cutter head. Would like to connect w/you thru VM website as I am also a member. TY

Dear Sir,
Thank you very much for your time and you help me how to connect the motor.

Can you explain how to connect booster switch to solar hot water heater system?

So are these what helps to not overload your grid when starting a 3 phase motor? As 3 phase motors don't have condensers like split phase does to help start them,?

Thank you. Thank you. Thank you. i really appreciate the side by side demonstration. I never really understood the overload relays and how they tied into the control circuits. Great down to earth explanation of it all.

Great explanation, my starter switch has failed on my Boxford lathe, so your explanation has helped me understand, which new switch to buy 👍

My god man....your workshop looks absolutely fantastic. 👀👀

Maybe you can help me diagnose a problem with a starter. I've got a step down transformer going from 480-120 to run my coil. I had the transformer on the shelf, and didn't want to order a new coil for 480v. Anyhow, my start and stop buttons work fine, however, if i manually actuate the contactor, the coil becomes energized and the contactor stays closed. I've never experienced this before. Any insight?

You can add normally open auxiliary contact blocks to the Allen Bradley or the Square D motor starter as to do the same thing as the American Rotary starter, the only issue with those smaller starters is the longevity of them. As a electrician for 40 plus years, to me nothing beats the old school AB 505 motor starter like you had there, they are bulletproof and will last a lifetime, I have seen way too many of those newer starters fail in the last few years.

Great explanation!

Thank you for video.

Great job Keith.

Did Keith ever utilise light indicators on his compressor switchboard to know when it's powered or in an error state?

Most excellent bit of information.

One of my mills has ancient DC motor controlled by a 1945 SquareD starter. It controls the startup inrush current via a dashpot and three resistor banks. It had been miss-wired and one of the internal straps was missing. If the schematic and care instructions weren't on the inside of the cover, I would have been out of luck. It works correctly now.

Well explained I have been an electrician for 50 years , that explains things very succinctly.

These things are worth about $1000 each here in Australia

great job explaining it

Essentially, latching relays.

I think society in general has given us a warped sense of what is “normal.” Finally, a video that explains it. Nomal(ly) closed - you get the beep. Normal(ly) open - no beep. JK!! Also, the overload section protects the wiring as well as the motor. This video will really come in handy when I get to the motor controls on my 10ee. Thanks Keith!

Even the way Keith draws the electrical diagrams is vintage. We haven’t used those little half circle bridges where wires intersect for 40 years. Since then the wires just cross each other, and when they connect, there’s a dot where the wires are crossing, to designate that they’re connected.

Sometimes that aux switch that’s normally off, is used for a brake.

There are also solid state contactors--no moving/mechanical parts and quiet.

Great job Keith 👏 👍
