Hey if any of you guys are looking for a job reach out to me on LinkedIn. There are many open industrial electrician roles. One of my buddies who's a recruiter is trying to fill a lot of positions across the country... I know he said they're trying to fill about 10 roles in the Chicago area looking for industrial electricians with some controls experience. He has 20 other open positions some of them are engineering some of them are controls techs some of them are instrumentations there's just a whole wide array but yeah find me on LinkedIn I'm not hard to find and I'll hook you up
What do you have a 9 month certificate or an associate's degree?? Search my name on LinkedIn and then just put Ohio next to it you can find me and send me a message I might be able to help
@@THEHANDICAPPERSGOLFWORLD-jd4lh hell I really couldn't tell you I'm in Ohio. Anyways as far as motor control wiring and stuff goes if you got the basics down pretty good generally speaking in not that hard to find a job in the US. We have a pretty good shortage on skilled trades if you understand programmable logic controllers electrical schematics and instruments it's very easy to find a nice paying job (70-100k/ yr), especially if you have any sort of certification or degree
Thank you for the nice comment… This is my best performing video. I’m definitely trying to make another one that will have similar results having a little trouble lol
Yeah, I was thinking it was dangerous because it was still charged. I would want to remove power altogether. I understand your goal for the video; it was a good lesson. Thank you.
You're welcome.. maybe I could be a little bit more clear about the safety warnings I've been doing this for a long time so it's kind of second nature but it is pretty dangerous
Hey thanks I appreciate that I was thinking about making a video about water pumping station that pumps water up and down based off level what do you think about that? Is there any other tutorial that you would like to see that one kind of show how relays work float switches and timers what are your thoughts
Good shit Greg. This is Brad O. You definitely made this easy to understand, not too heavy with contextual terminology, yet not too simplistic in a way that would be a waste of someone's time trying to learn this. Good stuff
How does the overload see the overload current on the contacts since its just running off the neutral of the coil terminal a2? Edit: poorly worded but I think you get what I mean
@@siphomayisela288 I don’t think I understand the question A1 is where the 120 V goes into the coil of the relay, the voltage is consumed through the coil and once that line comes out on a2 it is neutral. You then run that neutral wire through normally closed contacts on the overload relay. As long as the overload is happy that circuit continues (all still neutral on the OL contacts). Let me put in another way if you’re overload contact is happy. It allows circuit to run through it and behaves the same as attaching A2 directly to the neutral coming into the panel(running back to the source of power) when the OL trips that normally closed contact gets opened up and the neutral from A2 gets interrupted(like cutting the wire with sciszors) and never gets back to the power feed releasing the coil and turning off the starter. Everything after a2 is neutral (making it slightly harder to teat by the way you have to pur your thinking cap on a bit) If they didn’t answer your question rephrase it I’m happy to help
Yeah that’s completely fine, if you do have your overload in the neutral and you’re using 120 V AC if your overload trips you’ll actually measure 120 V on the one side of the overload because the current is not being consumed in Coil . This is very important, it doesn’t matter if your overload contacts are positioned on the hot side of your control circuit, or on the neutral side, You just wanna make sure your control circuit only has one path to neutral, which is through the Coil (A1and A2), Make sure you don’t wire a hot to neutral without having to pass through something that will consume the power that is a short circuit
@@michealplater9007 Also, I probably need to expand on the question. I don’t know how much you know about electricity, so I’m just gonna cover the basics. Generally speaking, you use a contactir when you’re running three phase motors so on a three phase motor, there are three hots, and then a ground. All the power for the motor runs through the three hots and the ground is used just in case. The there hots run through the contactor (aka starter) and your control circuit makes the contactor turn on. I am discussing control circuits, meaning the power that you used to tell the pump to turn on, not the power that goes to the pump. I’m assuming your question is in regards to the control circuit and not the actual power going through the contactor, a.k.a. starter to the motor. Lmk if that’s what you’re asking or if you need more information.
Yes you bring up a pretty good point... That's just how they do it more often than not. That latching circuit is pretty common I wanted to demonstrate it cuz it's not very intuitive . I guess the benefit of doing it this way is if you have an overload trip or hit a stop button it will not start the process back up when can you reset the overload or let go of the stop button
Why dint you used stop for Line, connect stop and start jumped to NO-1, start to NO-2 conected to COIL-1, COIL-2 connected to NC-1, NC-2 connected to neutral??
@@ricardotorresvela5538 bro I'm trying to figure out what you're asking and I can't figure it out that definitely doesn't mean it's not right though. I'm really curious I wish you could send a picture on here but you can't... Anyways there's always more than one way to wire stuff this is just basically a video about how most industrial motor circuits are wired this is like the basic template and then you just add to it
I don't understand the jumper from A2 to overload relay. How does a neutral open up the coil? I thought the overload automatically detect high current and kicked the contacts out?
Hey, that’s actually a great question… A lot of contactors will not disconnect the circuit when there is a trip. The big square D motor starters/contactors remain intact during an overload. There’s just an overload auxiliary contact on the side. That’s used to interrupt the start circuit now that I think about it I’m actually not certain, if the Allen Bradley overload automatically interrupts a circuit. I do not think it does but I am doubting myself now. I’m a little busy right now I might look into that later or if you have time Google it and post your findings here I’m pretty sure the legs of the contactor remain closed, even during an overload, but on this model they might open automatically
Yeah you would probably end up as an instrumentation or electrical technician. Start looking at job postings you'll get an idea of what's out there in your area
Yeah, that would be fine. I’m honestly not sure that might be the industry-standard my bad if I got that wrong. it should be noted this is a really simple circuit, generally you would have an e stop somewhere… there are many diffways to do it but an e stop will usually kill the whole control power circuit
It would not technically be safer. It would be the same thing but what you could do is put the E stop first and then make the relay circuit and the motor control circuit parallel after the e stop if that makes sense. The next level up would be have all the control power run through a relay that is energized via thru an e stop NC contact, or you could run it theu 2 nc contacts in series on the back of the same e stop. The right way or a.k.a. industry standard is to use a safety relay the way that works. Is you run 2 seperate circuits thru the back of the e-stop, the contacts are closed aka power runs thru at all times unless you push the e-stop. You can put multiple e stops or saftey devices in series, each device has both circuits running through it. Those go to a safety relay(they are red or yellow and look like a rectangular module with some lights on it). That card monitors both circuits, they need to have the same voltage and both turn on and off at the exact same time down to a few milliseconds. When the safety relay is happy, it will energize the contact that you run all the control power through other words with the safety relay is happy than your whole control circuit has power. There’s any violation meaning one of the circuits loses some voltage or they turn on at a different time. You will lose power to control all your devices.
@@donnellbaxter8050 that's cool I'm actually curious if you'd be able to transition pretty easily without going to school. Or possibly maybe you could just get some sort of like 9 month certificate and try to get a job as an electrical maintenance technician. I would appreciate if you could give a follow-up in a couple months and let us know how it worked out. Also I get it HVAC is pretty closely related but I feel like you have to subject yourself to worse environments especially if you live in a hot State I could see that getting old
It cant stay down because the stop button has to be in the normally closed position in order to open the circuit and prevent voltage from getting to the motor starter. Therefore the motor starter is a necessary step so we can "control" it by hand. You can do this with PLCs and relays with 0-10v on a VFD for more specific control environments with automation.
