Horrible narration and boring text - explain the principles and the circuit operation. DO NOT spend time telling the exact letter and number of each terminal. Dismaying.
Your videos are of high quality standards and every detail comes with the understanding I have been searching for I can wait for forward and reverse as well as Star delta wiring
Sir, how much current can the NC or NO pole carry without failing? Can it carry 10A DC for long term? I understand NC, NO poles are auxiliary poles and not supposed to carry power load as their contact area is also small. But I want to know how much current it can handle? Thank you.
I have a question. How can the contactor stay closed when the power over A1 and A2 is AC. In my mind the magnetic field would change directions 50 or 60 times a second depending on where in the world you live. Can you explain this?
Fantastic Video. Can you do one whereby you connect two float switches in two different tanks. One tank is the storage (on the bottom) the other is on a Tresstle...
Really enjoying your videos. Fantastic and clear animations, descriptions and connections. The pace and tone of the video is perfect for comprehension. As noted in my comment on how a contactor works. Some discussion on ac signal energising the coil would be useful for someone that is only familiar with relays whose coil is normally energised by DC.
Really enjoyed the video. Great animation. Clear and concise description of functional operation and connections to the contactor. Would have been nice to show the start/stop button connected with thermal relay. Well done. May be worth explaining how the coil is able to operate off an AC source as most people would be familiar with energising a relay coil with DC and not AC in the case of the contactor.
I like the 3d cutaway! I’m freshening up on trying to get a maintenance job at a data center for a company that is well known around the world and I have to say (as a visual learner) this was much more informative than many other videos that I have watched
Is the neutral run through the float switch? Mine is a simple two wire device. Seems safer to interrupt neutral with the tank float switch than 120v run through it.
You are showing a three phase service transformer. Three phase service is for industrial and commercial service. Industrial customers have large motors than benefit from three phase service. Residential service does not need three phase service because they only use single phase motors in their air conditioning. Residential only get single phase service and only use one single phase transformer connecting to a single phase wire and a neutral wire on the primary side of the transformer. The diagram of the three phase transformer is not required for this topic and the three phase Y transformer is in the substation and produces the typical distribution voltage of around 12,000 volts from the transmission lines.
thanks for this brief and very clear video. just the way i wanted it to be. its been a long time that i like to install a float switch by myself but not very convinced yet because of my lack of knowledge about stuff like this. i have also watched a lot of videos about this matter but none were conducive enough for me to abosrb the details. thanks and kudos!
