Thank you for the video, I understand motor calcs much better. Taking the big journeymens test next week. Wish me luck!
Great job! Very simplified!
Thank you very much for what you do , I just wanted to state that on motors overload we have to use next size down .
thank you i understand motors much better.
You sir, are the best thank you for sharing your knowledge 🙂
you are a very distinguished young man for this one.
Thank you very much Sir, appreciate you 👌👍👍👍👍👍👍👍👍
❤ thanks
On the overload protection we should use the nameplate times the percentage, right? This video says to use full load current from the code book but if you look at 430.32 it says nameplate full load current. Thank you for the videos.
For step 1, you should use the table in the NEC as opposed to the nameplate. That is because the motor may be replaced with a less efficient motor.
not for taking a test you dont
But now you're changing the electrical architecture of the system. Anytime you change a component, you need to investigate the impacts of that change.
Thanks for your videos, do you have a more robust test prep program for the journeyman (2020Montana) test, of what prep test program do you recommend.
I do not. I teach JW prep for a college in Alabama. I use Tom Henry material for the class. I do have other videos for motors, ampacity, and ranges.
🙏🙏🙏👍
Shouldn’t the answer for the 4th question at 13:44 be 50 since the temperature is less than 40 degrees Celsius??
Your right man I got 50 amps also
Yeah I got 50 as well
Wrong. If it does not mention the service factor OR the temperature you use the 115% column.
In the slide before he starts answering where he says to pause, it specified 35°c
At 12min 40sec
Can you do steps 3, 4 and 5?
Does anyone have the answers to the questions he left at the end?
Someone know how to calculate a 300hp motor and its cable size use?
