If only my professor who I paid lots of money to knew how to teach this good. This school system is wrecked.

You have a gift for simplifying complex information and communicating it in a humble way. Keep up the great work 👍.

This guy is such a WONDERFUL Teacher !!! Love You Dave .

As many of the viewers who have commented, I am also an engineer and have been at work for over 50 years and still working. Dave is a unique individual. He can present education clearly. I enjoy his videos as a learning and refreshing program.

The clarity in this man's explanation is second to none

State of Michigan journeyman electrician here: thank you for helping me understand that a little more. 🙏

The importance for ppl Like you who oversimplify everything is very much needed . thank u

One of the best explanations of the types of OC I've ever seen. Bravo.

Sir, I appreciate the time you put into these videos.You are Definitely one of the best out here.

I came across your presentations by chance while boning up for an upcoming interview. It takes me back 30 years to when I was in tech college where we had two brilliant lecturers, Elwyn John - electronics & Mike something the electrical guy. Like you they both had the same clarity of presentation, free of waffle, not bogged down in too much math where it is not neccessary, concise & engaging. Well done!

Thank you so much. You certainly helped a lay person such as I who is not of the electrical profession to understand the nature of overload and faults that result in overcurrent. You mark out the differences so very clearly.

I would love to sit under your mentorship. Was watching your class on temperature consideration for over-current protection and it brought it all together. Thank you Dave.

You're a sure master of your arts. Feed me more and more. Thanks for the awesome presentation.

You are such a great teacher. Your explanation is very clear and understandable. Thank you.

Great teacher and a great level of understanding , thank you for these

Thank you for this video! I wish I had this from back when I was studying these concepts in Uni. Well done sir! 👏🏽

Subscribed. I have been in the electronics biz since 1984 and you sir are someone I could watch for hours. I was blessed enough to have my high school and college professors teach well and convey the rules and laws clearly. I would put you at the top of the heap. Thanks for making fine videos.

This video is such a gem, every instructor should share this with their students. Good job.

Sir! You are great at what you do. Very clear and concise.

Thanks for another excellent video, Dave. Years ago an old timer explained to me, basically the circuit breaker's job is to protect the wiring/equipment, the GFCI's is to protect you!

Perfect lesson again. I got to test circuit breakers using huge, Frankenstein-like test sets with 6" diameter knobs., analog and digital meters and timers. What a BLAST!! The three basic tests were long time, short time and instantaneous to determine how well the circuit breakers performed under actual load. The first test set was the transformer/controller that we fed with 480 single phase which dropped it down to a very low voltage C clamping large cables to each breaker phase then applied current to each until the breaker tripped. Instantaneous (depending on the test curve of each size, type, brand...) was about 10 times the breaker rating, short time was about 5 and long time was around twice the breaker rating.

Thank you. I needed that refresher. I plan on going back to school for electronics. I haven't practiced electronics in over 20 years.

Love his videos! 3rd year Union apprentice here and I come running to his videos they just make so much sense!

If I am going to listen to someone go in depth in extremely technical subject matter,I must like the person & their voice can't annoy me,this guy ticks all the boxes and holds my attention,love these videos.❤️⚡⚡

You're saving my ass in electrical school. You're the best teacher, seriously. Thank you

Dave, I recently discovered your videos. Outstanding job explaining and very helpful illustrations. Thank you, I hope you continue to post more content.

Great refresher video. Getting ready to train a new employee. Sometimes putting to words what you already know is tough. This was a great explanation.

I just came by your video, and I'ld say you did a good job in explaining the concepts. I hope to see more of your videos. Thank you 😊

Great having the basics clarified. Thanks

i hope i have teacher like you when i am young..

I don’t know why, but watching this video gave me a eureka moment. The reason an inductor can overload when there is LESS voltage is because the inductive reactance is less causing less impedance! And lower impedance means MORE current!!!! Holy shit! And that’s why dimmers aren’t suppose to be used in fans! Because they increase the resistance of the circuit which causes less current and the less current results in LOWER impedance and the lower impedance causes more current! Holy shit I am so happy it clicked!!!! I don’t know why which this specific video man but u are awesome! Im like level 4 nec but this always puzzled me and none of my instructors could make this link for me! Don’t stop what ur doing!

Thanks for all the helpful information, as you go it would be great to get an in-depth understanding of the geothermal and how to get it in various environments from west coast to east coast!

Wow. Like so many have commented, this man is a gifted educator.

I appreciate your succinct explanation. It will assist me in finding an electrical defect in my driver's side indicator light circuit. Thank You.

the way that you simplify concepts amazes me thank you so mush

Good example with ground fault. But I would always give two ground fault examples. One like yours where the fault goes to the ground wire. And another where the ground fault goes to the dirt/earth/water and doesn’t touch the ground wire. Then I would explain that both types will trip gfci. This gets people to think and realize that the gfci device can sense a fault where the ground wire is not involved at all. This way people can understand that gfci works correctly on a circuit that has no earth ground.

you are one of the best tutors. I am satisfy with the way you explain everything in details. best explanation ever!

Powerline Technician student here; I have been looking for a way to wrap my mind around the concepts. How I phrase it to myself is to "Dumb it down" to myself. This helped me so much as I am going into 3-phase and still had to figure out the basics, not just remember the formulas, etc. Thank you so much. I am going to keep watching a your content instead of Karen videos.

your an excellent instructor that i have ever seen , good job and keep working , you make the information to enter my head as fast as the short circuit interrupting happens 😂😂♥

Dave is such a great teacher. I love his vids.

Dave, this is a great way to explain. ! Keep it up.

I'm an engineer constantly learning and re-learning. You're spot on here mate. Good to listen to your presentation. 👍

I loved the way you distinguished between overload and short-circuit

Thank you sir for teaching me electrical principles I find them to be so helpful down here in Malindi Kenya.i will crave for more,thank you sir.

Wonderful explanation!!! Sending love from the UK

Wow, fantastic breakdown!!! Thank you sir

you have a talent for explaining this stuff. It can be hard to grasp especially if someone is boring and monotone. The dynamic explanations were helpful to me. Thank you ~sub'd

Well explained and clarified. I really appreciate it. Thank you.

Thank you for sharing your knowledge, sir.

Thank for illustration and very comprehensive discussion

thanks for the great explanation :) was always confused about these terms.

Very well explained. Keep up the good work!

Thank u Dave . Your content helped a lot.

His example of ground fault tripping was showing a fault on the supply lines. That would indeed trip a gfci circuit breaker; but it would not trip a gfci outlet. Since most houses use gfci outlets and not gfci breakers the example shown is misleading. Otherwise a very good video with much good information. Well done.

nice video gretings from Guatemala hugs for you thanks for share

Everybody in construction should be watching your videos.

I saw your video, it is nice to see how it is explain, I remember long time ago when I have to master a Power system of a very Complicated Big Power Plant, Transmission and Distribution Line when there are different kind of Load for Commercial and Industrial costumer. Before we have the Westinghouse Books now we got software to solve this problem.

Well made video, i think this simplify things to total amateurs and even some professionals

I love your explanations sir!!

Fantastic video, thanks for making this!

Hey, Electrical engineering student here! Love your video explanation! Pax Vobiscum.

Fantastic instructor.

Best explanation I've seen in my life🙏

"Soli deo Gloria", pretty cool :) God bless! Greetings from Norway!

I just discover your channel. Excellent presentation and explanation. Please make more

Amazing explanation 🎉🎉

You are better than channels with 10x the budget.

Very impormative video, Tnx for sharing Sir

wow, this is outstanding, i now dislike 'short circuit' as compared to 'ground fault' because 'ground fault' is a more accurate way to describe it

Even though its electricity basics, I appreciate the way you dumb it down to the point a 5yr old can understand it. Especially since theres no way of knowing who your audience is. You teach it like your introducing us to the concept of electricity

teaching and explaining is really your talent.

your videos very helpful .outstanding explaining..thank you

You must be a teacher. Great video man 👍

Really amazing stuff!

Thank you. This was a very good explanation.

Great explanation 👌

Making things clear and simple. You didn't impress me with knowledge, but with the way You explain matter. That is a very rare talent. Even if I know all your lessons well, your interpretation makes them refreshing. TY for excellent experience.

Thank you for your splendid explanation

Very helpfull explanation. Is it possible to see a video of the relation between an LSIG breaker and the types of overcurrent? Thanks for the video!

That was an excellent explanation and made very easy to understand. Thank You! Subscribed😀

Amazing explanation. Thank you!

Thank you sir for the clear details and information God bless you

This is an excellent video... Thank u

Thankyou, you’ve really simplified what I needed to and understand for my final exam :) Louise

Great teaching , thanks for sharing.

Properly explained. Thank you sir.

so direct and clear explanation.

Basics is very important.thank You Sir.

Jeez Louise, thank you SO much for this video

Very nice, enlightening 💡, no short circuit ! 👌

Great demonstration sir.

Currently in trade school your videos are helpful

Thank you for this wonderful explanation.

excellent, clear explanation

If only my teacher's could teach like this it would have been awesome 👍..

Great video.

Nice explanation lots of love from Nepal

this man is GREAT

The world's best teacher thanks

You made it so easy for me to understand 😊
