i've said it before to you, i am a retired electrician. now i never cared to learn about starters, but one day, my boss put me in a building to run work, and a lot of the job, involved starters. it also involved a lot of fire alarm work, and HVAC work. boy did i have to learn fast. i ended up spending 10 years in that building as a foreman. ok now just one thing i just saw on your wiring, that i am going to tell you about. whenever you are using stranded wire, no matter on what, if you are going to put a stranded wire, under or around just a screw, twist the wire counter clockwise. so when you put it under or around the screw, it does not fray up, and leave some loose ends from under the screw. watching you has taut me a lot about logging, so i felt i could teach you one thing about wiring.
Wrong, wrong, wrong, wrong, use a stake on compression lug. Never ever wrap stranded conductor under a screw, only solid conductors are suitable for that.
Daniel Eyster I came through the 5 year inside wireman program with the IBEW. Class two nights a week and work all day/weekend sometimes for 5 years. It’s been a rewarding career and taken me places I’d never imagined. I left the construction side 12 years ago but now am an E/I technician for one of the largest pulp and paper companies in the world. I never forget where I came from and what all those old timers taught me over the years. Stay safe brother!
😂😂😂 I was learning how to meg a motor from the bucket and my buddy teachin me kept repeating over and over "watch your hands" and thats all I could think watching him in there
momentary hot,momentary cold that's the first time this electrician has ever heard that if you want to get technical the right wording is normally open for the start and normally closed for the stop. You had the correct lingo for the neural on the control side you just had to think about it (really hard).
I believe you explained it better than most electrical videos. you pointed out where the wires are going and what they do. I noticed most of the others just say it goes here and don't show it.
I'm a home owner electrician. When the wife says a light bulb burnt-out, I change it out with a good one. But I know one day, this vidja will come in handy for me. :) and knowledge is everything!
The sun shines a little bit brighter when you have figured out a latching circuit and understand it!! i remember when I did, I was walking taller and couldn't explainnn to people why I felt so proud. It's not running off of FM (Fu**ing Magic). Wade good job to you, and Happy Birthday, Matt
That camera perspective had me freaking out. Part of my brain knows either your far enough away from those leads or it's a dead circuit. The other side of my brain was waiting for you to get zapped. Glad the first side of the dome was right haha
I'm not good with electricity but on are rock crushing plants we run alot of 2 to 300hp motors and most everything is 480v kinda scary if u don't no what your doing but I have been around it a long time. So I learned alot. Keep r safe Mr. Wade
Your top section is the starting contractor which has a relay to close and hold close the contractors to supply voltage to the motor. The lower section is the overload heaters like you said. Current passes through the heaters and if too much current is drawn then the heater will trip open a set of contact which de-energises the supply power to the contactor coil and all the contacts open. The heaters are sized on the motor you are using and generally there is a range of heaters you can choose depending on the amperage you want them to trip. If are getting a lot of trips then you might want a higher rated heater. Also, you might want to check the contacts are not varnishes and causing resistance.
Get a good fluke meter. Get to.know ohms law how to test a motor if it goes bad an how to determine ohms of resistance how to test fuses. Learning ladder logic to wire up circuits is important. Would love to come an help out for a day. Maybe me an my brother can someday
Probably one of the most dangerous voltages out there. I'd say it kills more electricians a year than any other. Always keep your booger hooks a safe distance away. good vidja tho! keep on keepin on!
You got almost all of it right. The 120 volt that keep the contractor pulled in is hot until the stop button is pushed. The circuit is called the seal-in circuit. These kind of circuits are used with momentary switches. On the Over-load the contact that has the neutral is a normally open contact. When you push the reset button for the overloads it closes that contact. Other than that you are getting a good grasp of what is happening. Good luck and be safe. You will find that the start-stop circuit is the same for single or three phase.
Looks like you got the understanding on how it works, where I worked we had mcc in every building with what we call buckets with all the things inside that you had except ours has a step down transformer for the control voltage every bucket had one.
That’s a neat gig you’ve got. 3 wire control circuits one day and logging the next. I envy you. I know you’re busy but that variety would be nice coming from a maintenance electrician
The reason heaters trip are the amperage draw of the motor, they are design to protect the windings of the motor incoming voltage has effect on how set your heaters lower than normal voltage means your amperage draw will be higher, every action has a reaction
Next time you have a question, throw it out there to us. I do industrial maintenance and firewood/ tree work on the side. Sounds like you have a decent understanding of what going on there though. Better than some of my guys. You'd be surprised at some of the guys I work with that think 110vac will work without a neutral. Anyhow, respect it for sure. Get yourself a good meter as Eddie said. Fluke, Green Lee....... A must have tool for sure.
When the light bulb doesn’t come on I take it out and shake it, if it tinkles it’s time for a new one. Or if the grain augers stop I let it cool for a bit and then push reset .. lol
I’d say you’ve got the basics of starters and start/stop control stations figured out. It is a good feeling when concepts like that finally click, and make sense. Up until that point, you feel kind of dumb when you don’t understand it and others do. Of course not understanding it doesn’t mean your dumb, just can feel that way. Good Vidja! Thanks!
You don't break the ground to stop it. You break the hot. If you break your ground, and it stays hot, if you become the ground by touching the wrong spot, power goes thru you and tries to start the motor and your innards is not going to like that. If you break the hot then you touch the wrong spot it doesn't hurt. That's just the control side of things
It can be done both ways, I work in a plastic plant and every starter we have the overload contact runs through the ground, no matter which way you choose to do it there will always be 120v or whatever control power you're using present in the starter. As long as you open the contactor it doesn't matter which way you do it
It will help in troubleshooting 3 phase starters, if you think of them as 2 separate devices. The high voltage contactor ( essentially just a relay ), ... and the overload segment, where the thermal units ( heaters ) are mounted. Hydraulic circuits have a "work" circuit and a "pilot" circuit. In 3 phase electrical circuits, they're called the "load" and the "control" circuit. And YES it does matter that you use the correct terms, in order to accurately communicate with vendors and other electricians. Nobody should have to GUESS at what you mean. I'm a laid back good ole boy myself, but sometimes, in technical language, precision is important.
Dang, wish this video had popped up for me 12 hours earlier, I would have bought some stuff I didn't bid on at an auction. Got confused and should have thought about it more. oh well.
Up our way we still have alot of old delta open 3 phase. No neutral to be had. Pain in the ass ! You cant grab single or two off of it cause no neutral. So if you need single or double. You gotta shove it thru a converter. Pain in ass and expensive. Very efficient if your just driving the 3 phase it was ment for
Depending on coil voltage, A2 isn’t always neutral/ground. That’s a more complicated starter to learn on lol. Sounds like you have it for the most part. Be safe
It’s called the “seal in circuit” buddy, keep on learning and most importantly be safe! That’s dangerous shit and saving a couple bucks isn’t worth your life.
Yelp that’s about sums it up. That’s how it works FYI in behind the heaters on a square D they’re a Sauter pot that the heater heats up that allows the mechanics of the over load take it out. Electrical works like hydraulic in a sense.
Don't know if it'll help but in our marine sanitation pumps the start system was parallel the stop was series, . Any openings in the stop side anywere made everything stop
@Logger Wade Let me know if you need some controls, i do building automation and i could get you some nice automation for these bad boys with current senors, temp sensors, phase loss monitors, the list goes on and on. We can do 0-10 VDC and 4-20ma inputs and outputs. Using the smaller relays to drive the 120's you have now. It would be like a computer for all your electrical! I could set this all up so you could monitor and troubleshoot, test all from your phone, tablet or pc!
Never get in a hurry.. PPE ALWAYS. CLOTHING,BOOTS, LOCK OUTS.. MY FRIEND DID NOT USE A LOCK OUT,THE FORMAN CAME DOWN AND FLIPPED THE CIRCUT, MY FRIENDS ARM WAS IN THE MACHINE, YOU CAN GUESS WHAT HAPPENED.. SAFETY..
A reverse starter has an interlock between the two halves so you can't pull in both sides at the same time and create a short between the two swapped legs
Dag- gone, we had three calves today and sence the last two that were born yesterday there names were Calvin and Jackson so I might as well name these three Anne, wade/tater, and Stevey.
Buddy it gives me a head ache your eyes are looking one way your fingers are pointing 2 different directions , it would drive me nuts thanks for sharing
I personally dont like to see someone just learning , trying to "teach"(no offense) Also... learn proper terminology, because your gonna get yourself or someone hurt if you say the wrong thing or follow someone elses instructions improperly BECAUSE of improper terms!
