Overcurrent, Overload, Short Circuit, and Ground Fault

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 👍.

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.

Great job explaining! you hit important points without talking about unrelated things or rambling. Also very engaging energy!

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

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

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!

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

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.

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.

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

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!

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

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

Thank u, way easier to understand it this way

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.

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.
