Really like the explanation and descriptions of the 2 different types of heaters and on how they work... Great directory and help... appreciate the video
You are an amazing instructor... ive been searching for videos like this. MORE VIDEOS PLEASEEEE...about terminations, wiring, corrective and preventive maintenance of of motors, transformers (dry/oil), and other industrial machines and equipments. THANKS FOR THIS VERY EDUCATIONAL VID. Im from the Philippines and I really appreciated this. Your vid helped alot for cadet electrical engineers like me. thank you.
You all probably dont care but does any of you know a tool to get back into an instagram account..? I somehow forgot the login password. I love any tips you can offer me.
@Issac Ray thanks so much for your reply. I got to the site on google and I'm waiting for the hacking stuff atm. I see it takes a while so I will get back to you later with my results.
Very informative! Great to see how the pawl actually instead of just a diagram in a text book that is completely different than a real world mechanism.
Thank you for the explanation and I'd like to further congratulate you on your ability to clearly & concisely convey your ideas. I'm subscribed and look forward to your productions. Great video
You should make more videos. This and the pressure switch videos are really good. I wish I knew of a RU-vid page that had more machine maintenance and repair video
very very good video...i learned it better in 10mins than reading it in the book...thanks for sharing. btw, does anyone know what is or how a "late break" contactor works in a resistor type motor starter? it's a N.C. contactor installed just after the start switch.
can you please explain the control wiring on that starter .from the auxiliary wire at top, were does it go from there? i am not sure about all the red wires were they go. thanks good video
Thank you for the detailed explanation. Quick question: How does the Auxiliary power differ from normal line power L1, L2, L3, like why do we need the auxiliary ports. How does the Overload wire move the contacts since the power is supplied to the relay coil through the push button, can you explain more on the overload circuit. much appreciated.
Mohit, the auxiliary contacts are just that, a set of dry contacts. When the coil closes, it "changes the state" of the auxiliary contacts. You can connect any separate circuit to the aux contacts and use the contacts somewhat like a switch. Typically you can have a light that lights up when the motor starts, or a discreet input that is energized when the motor starts to let the DCS or computer system know the motor is running. As for the overloads, they have their own set of contacts, and you wire the control circuit in series with the overload contacts. That way, when the overloads trip, your control circuit for the coil OPENS, and in turn, opens the line circuit and shuts down the motor, protecting your wire and equipment. Hope that helps.
I have a very similar MCC starter which is blowing the fuse on the control side for the coil. Nothing shorting to ground. Put a different starter in and still blowing?
Hey Randy great video...If I have a 120 volt coil circut does my 110 volt control go to 2 on the holding contact and my neutral go to the bottom overload?
I'm looking at my NEMA 1 Motor starter and the lever looks like it's stuck in a certain position. I don't see any visible damage, Is there anything I can do to repair this or should I just replace this motor starter.
I have a 230 volt single phase air compressor with a similar motor starter with a voltage issue. At L1 L2 where my incoming power lines connect i`m getting aorund 204 volts when the compressor kicks on then it goes up but where the power lines for the motor connect T1 T3 i`m getting around 166 volts when it kicks on. The compressor struggles to start at times. What could be the problem?
I'm connecting a compress that has this type of motor starter. We have 3 phase in the building. When connecting to service, is it: L1 120; L2 220; L3 120; ? The motor is wired for 230V.
