Basic Motor Control: Pump Panel Wiring - Part 2

[@CommercialGasEngineerVideos]

Based in the UK but the principles from this video are still helpful. Thanks

[@johnszott956]

Great video! I like how you incorporated both schematic and real video of panel box with you showing routings. Keep up the great videos!

[@CommercialGasEngineerVideos]

True, it helps having both

Great video! Thank you for all the support!

Your the best man ! Thank You for sharing the knowledge 🙏🏽

[@SelinaAl-Shaer]

I love the way you take your time and explain the practice and the theory behind whatever it is you are explaining. Do you have any NEC code videos on you tube?? if not, I really think you should cover code videos. i know everyone watching you will be interested in Code tutorials. Thank you.

[@AccessToPower]

Thanks for your comment. I have a couple videos on the NEC for conduit fill and enclosures. Thanks for the suggestion to create more

[@rommeldc4787]

Thanks! It so useful

[@samuelpowell87]

Good job

[@nickledimez4012]

Beautiful explanation! I learned more from you than in my class. Have you considered a manual or book on this subject? I have text books from school but loaded with a lot of jargon. Your explanation is straight to the point and concise. Thank you sincerely!

[@AccessToPower]

NICKLE& DIMEz I don’t have any books yet. It is a long term goal though

Great Video!!

Well done...

[@jimmurphy6095]

Very nice... How about a lead/lag pump setup? I see a lot of those.

Greetings! I absolutely love your video. I am a rookie. May I ask a question? I am trying to "make sense" of the wiring for the auxiliary contact (red jumper and yellow wire). Which one is the grounded (neutral) contact? Since the jumper is coming from what appears to be the "hot" wire and the yellow is coming from the "hot" start wire, why doesn't this result in a short-circuit. I guess if I were to ask the question differently, I see the 120v loop for the coil with a grounded and ungrounded conductor. But for the contact, which kne is grounded and which one is ungrounded? Any help is necessary and thank you for taking time to review my question.

[@AccessToPower]

Hello and thanks for watching and commenting. If you look at the video and go to minute marker 6:08, you will see the red wire from number three going to the coil and to one side of the normally open auxiliary. And you will see the yellow wire coming from our hand off auto to the other side of the auxiliary. Keep in mind that both of these conductors are fed from the same power source. They are basically the same wire except at the red goes through the normally open start button and the yellow does not. The yellow effectively bypasses the start button. As for the ground in neutral conductor that is coming from terminal 95 on the overload directly to the other side of the coil. Since the red and the yellow that I mentioned earlier are basically the same wire, there is no potential difference between them and that’s why there is no short.

[@rw5838]

@@AccessToPower Thank you so much for your kind response! This made perfect sense to me when you pointed out that they both come from the same source, which is why there is no potential difference. Your videos have really helped me apply many of the concepts in the NEC Code Book. Thank you so much for all of your awesome videos!!!

[@michaelcostello6991]

Lots of these pumps are controlled with small PLC and the float switches or pressure switch. Can you do a video on this.

[@AccessToPower]

I will try to do that. Thanks for the suggestion

[@viswanathaniyer2372]

nice video

[@nukeelda]

Amazing keep it up ...

[@petersmith9254]

Once again thank you for this videos will you do something with drives or vfds

[@AccessToPower]

you're welcome. yes I am getting ready for a vfd video now.

[@ericmaldonado1373]

Great video, if you get rid of the background music...it would be perfect 👍

[@rajinig1599]

Good, please show float switch also practically!

[@rjwatford]

Is there anything saying the overload aux contact is required to be on the neutral side of the contactor coil?

[@AccessToPower]

if the coil is 120 volt then the neutral would go through the NC OL contact. If the coil is 240 volt then you would run Line 2 through the OL. Same goes for a 480 volt coil, you would run line 2 through the coil. This kills power to the coil if the OL trips. If you dont use the OL contacts then the OL will not turn off the starter in the event of a overload.

[@nyustdent]

can the floar switch also be a REMOTE SCADA control like from a DCS? would that be a 24v signal coming in to control a relay to close this contact?

[@AccessToPower]

Yes that would work

[@mindaugasv85]

3:12 2-phase 😉 4:00 by grounding you have lost protection... Without (!) ground it will work as isolating transformer, so if you will touch the control wire, you will not be shocked by voltage 😊

[@edwardgarza5104]

What's the reason to used a lower voltage for control? Could they make the coil on the motor starter 480v coil and would eliminate the transformer?

[@MackLife87]

Late but, 120 is safer for hand control in the case of a short

*Series connection* of smart motor controller to traditional (electro mechanical overload relay type)motor controller, which wired to *single/same pump set*. (Twin / *dual* motor controllers for the only one pump set), Then,What are the *pros and cons*/Hazards, due to this type of wiring connection?? #Please *clarify and comment*
