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

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

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.

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

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

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

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

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

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!

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

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

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.

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

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

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

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.

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!

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

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

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

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

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

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

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

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 😂😂♥

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 😊

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

Great having the basics clarified. Thanks

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 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.

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

nice video gretings from Guatemala hugs for you thanks for share

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

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

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

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.

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!

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!

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

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.❤️⚡⚡

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.

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

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

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

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

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

Wow, fantastic breakdown!!! Thank you sir

Thank you for sharing your knowledge, sir.

Everybody in construction should be watching your videos.

Very well explained. Keep up the good work!

Fantastic video, thanks for making this!

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

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

I love your explanations sir!!

You are better than channels with 10x the budget.

Really amazing stuff!

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

Thank for illustration and very comprehensive discussion

Thank u Dave . Your content helped a lot.

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

Wonderful explanation!!! Sending love from the UK

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.

Fantastic instructor.

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

Best explanation I've seen in my life🙏

You must be a teacher. Great video man 👍

Great video.

your videos very helpful .outstanding explaining..thank you

teaching and explaining is really your talent.

thank u providing us valuable knowledge

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.

Amazing explanation. Thank you!

Thank you. This was a very good explanation.

Thank you for this wonderful explanation.

The world's best teacher thanks

Thank you for your splendid explanation

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

Very impormative video, Tnx for sharing Sir

this man is GREAT

This is an excellent video... Thank u

Golden! Thank you!

Amazing explanation 🎉🎉

Basics is very important.thank You Sir.

Great explanation 👌

Currently in trade school your videos are helpful

Properly explained. Thank you sir.

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.

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!

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

Great teaching , thanks for sharing.

Perfect explanation... i Iove it

Jeez Louise, thank you SO much for this video

You made it so easy for me to understand 😊

Thank u, way easier to understand it this way

Thank you Steven Gerrard

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