contactor self holding with push button | start stop button | on off button | ELECTERCA 

Good job Mr engineer keep it up

How are you , David ..this is David Palmer Automation/ Electrical Controls Specialist @ Coca-Cola Bottling ( Los Angeles CA). Power goes through the NC stop switch, then to input side of NO start switch-where it branches off to one side of the Contactor connections ( as you have connected with the brown wire from A1 to the opposite side of the Aux. Contactor - that will go to the other side of the stop Button. Very good my Brother!

You are good

Hi.. you make it really easy and simple.. make it with light or lumb.. thanxx

Great. I am getting to like control circuits all because of you

I do like the way you do teach, it is overly simple to understand. I have been watching your video for a while now and since I did start watching your video, I have become one of the greater engineer

Amatuer learner here.I've done on off switch m1 and on off m2 but m2 attached to control m1 as a priority Till end of the Is my 1st time I've done and it failed. Need to energized m1 1st and th3n energize m2 as 2nd switch to on it.

Welcome David

Yes i know these motor contactors with holding coil. Mostly for 3phase >10hp. Wye start(star), delta run. The push(start) button will energize the holding coil to pull down the contactors and switch the motor n bypassing the start button. 3 contactors wil control a motor. With the main/wye(start) for sec then main/delta(run). Controlled by a timer. Stop(button will cut off the holding coil.

Bro , thanks so much for sharing your thoughts with us, it's really helpful but please can you make for me a practical wiring for the motor three phase from the beginning with phase monitor, timer, relay , contactor with starting buttons and indicators

Great videos Can you do a video with a dual pump controller with alternator.

I want you to do a control circuit for me. One about a lift station being controlled by a high float and a low float switch

I'm here again

Super

The video bro I think you should keep the old way of presentation ..sioni poa....otherwise it's a good job🤝🤝

Thank you mr David how does currencies move from controller to starter contactor in FCU?
