Thank you for a simple logical step by step tutorial very refreshing, most that I watch have so much useless or senseless dialog that I want to scream. Very glad to have found you!!!
Love this right now! walking into my motor controls midterm and hasnt been explained in this way so have felt very stressed. we've been wiring up starters on a wooden project board with the power being a power cord, and visually it is not very helpful trying to relate it to how it might look in the field, and the teacher has us wiring them up after we do homework assignments out of the book, instead of walking us through the testing techniques or how to wire them/just expecting us to know everything from the book, and it has been very difficult for me, a visual learner. Ive luckily been wiring them correctly, but this helps visualize everything so much better and makes me feel very confident. thank you so much for this video. the ladder diagram videos are helping me alot as well; i understood how they worked, but also not very confident on drawing my own and your videos are helping me so much!! thank you thank you.
On question Pete. In what line number you connect the high voltage wire when you are installing 3 phase motors. I have 2 wires at 120 v each and another of 200 volts. Thanks in advance for your answer. Thanks for the instructive video.
Hi! I have logic written to control the coil on and off on the motor starter according to level setpoint. The logic can latch the circuit, so do I need the holding contacts anymore on motor starter??
Hello Pete, I really appreciate these video. I notice that you have a smooth "drumlike" attachment on the shaft of your motors. Is that a belt pulley or some training device that you install so as to prevent snagging of clothing?
I believe our tech, Sam, had some aluminum machined to connect to the motors. Back in the day we used to used wooden clamps on these units so that we could simulate an increase in loading on the motor.
The control circuit in blue coming off L1 is fused to 1 amp. The 208 coil draws less then that. I’m installing a NEMA 1 thats fused with a 3 phase disconnect. Can I add this to my starter bucket. This circuit will be wired in on a pilot relay to a low voltage controller.
Hi! Quick question do you have to use a holding contact with the coil? I have logic written in a program that no longer needs a holding contact on motor starter using a set/reset block in function block.
@@PeteVree yes I am aware of that.. just wanted to make sure I can use my logic now to pull in the coil for the starter without using the holding contacts now.
@@PeteVree I have currently a motor starter that was wired 3 wire control without logic… now I am adding a plc for control of the motor starter… I can wire it as a 2 wire starter now. There is no start button, just a selector switch from off to auto. It’s becoming a fun project and appreciate your help!
On the NEMA starters, the overload Normally Closed contact is located on the bottom of the Overload Relay that I am manually tripping with the screwdriver.
Hi guillermo garcia, our classes are for electrical apprentices who are currently working for an electrical contractor in the Toronto area and are indentured apprentices.
The mcb is more accurate as fuses are so old school more expensive and a pain to change, also overloads are disappearing to most people uses something like a gv2 combined isolator circuit breaker and overload. In the UK panels should have finger protection on all live terminals that way you can work in a live panel with no chance of accidentally touching lives.
Hi Michael, it actually says 1 & L1... meaning that that terminal corresponds to L1, but will also be used as the supply conductor for your controls, in which case it would be numbered as wire #1 on your control diagram. The 2 3 to the left then corresponds to the normally open holding contact, which would then have wires #2 and #3 on either side of the contact.
@@TheMarkoPoloProgram I'm usually checking in to make sure everything is in good working order... you probably saw me when Dave and I were trying to figure out the new DC Power Supply the other day. I hang out in C533 if you need anything.
then pan in later with a zoom in ahah I like this content! this kind of humour is easy listened. Just can't wait to know more about thoses bad boys out there. The highlight of some details the the circuit that are particular in a academic situation, really awesome!
In our shop the wires simply go to terminal blocks on the left hand side of the starter enclosure, so there is nothing connected to the coil at the moment I am taking the resistance reading.
In a real troubleshooting situation, the coil may be powered by the 24 v, so it is the 24 volt coil that can be read if the wires are not removed. I sincerely believe that it is preferable, to show a sure method to measure a coil for student.
OK. Noted. Out in the field, please remove the wires from the coil so that you make sure that you are only reading the ohmic value of the coil. But again, in this video, the disconnect is in the OFF position, which means that there is NO power to any of the components, and nothing is connected to the terminal blocks.

Yeah, your videos are better than Netflix.
Excellent demonstration. You explained everything so clear.
Very good job explaining how it works !
Simple and easy explaination.
Great video!!! I only wish u would have had a camera to catch the specific details !
thank you for this information
thank you for free lesson thank so much

This video does not incorporate a PLC. The holding contact is required to maintain current to the contactor coil.
@@PeteVree yes I am aware of that.. just wanted to make sure I can use my logic now to pull in the coil for the starter without using the holding contacts now.
And thanks for the video and your channel!
@@stephenhillman3086 Yes. The set/reset would negate the use of any holding contacts

EXCELLENT video. Thank you
Glad it helped out. Thanks for the nice comment. All the best. Pete
Are those 3 line wires carrying 120vac? 120*3=360
When you tested the overloads, where did you place the meter leads I couldn't tell on the video
On the NEMA starters, the overload Normally Closed contact is located on the bottom of the Overload Relay that I am manually tripping with the screwdriver.
A push u push the overload and if it tuff it trip and if it safe it reset
Very very helpful
Great video!
good explanation
I’d like to take some class for the next year can you give me the website I can apply

I love all the videos.
what does the 18 stand for in front of L1 label on contactor ?
Hi Michael, it actually says 1 & L1... meaning that that terminal corresponds to L1, but will also be used as the supply conductor for your controls, in which case it would be numbered as wire #1 on your control diagram. The 2 3 to the left then corresponds to the normally open holding contact, which would then have wires #2 and #3 on either side of the contact.
Is this George Brown College?
Yes.
@@PeteVree I feel like I've heard your voice before. Are you sometimes sitting in Dave's shop class?

👍👍
Except for a bit higher pitched voice , you sound like the comedian Norm McDonald... that’s so funny. Oh, great teaching video, very thorough.

@@PeteVree OMG, that video was hilarious, he is so funny. It must be a Canadian thing... thanks
where is your classroom located
Toronto, Canada
Thx A LOT 👍🏻

when you have to take mesuring the coil, you have to disconnect wire on it
In our shop the wires simply go to terminal blocks on the left hand side of the starter enclosure, so there is nothing connected to the coil at the moment I am taking the resistance reading.
In a real troubleshooting situation, the coil may be powered by the 24 v, so it is the 24 volt coil that can be read if the wires are not removed. I sincerely believe that it is preferable, to show a sure method to measure a coil for student.
