Just started work as an apprentice, I don’t start school until September but there are so many things I’m curious about, thank you so much for putting this together!😊
Welcome to the industry.
Eric, ever the master of tying it all together: the foundation, fundamentals, and practical application.
Great job, you are an icon to this trade Mike Holt and I greatly appreciate all you do to continuously promote this trade while educating us all. Blessings galore !
Thank you and God Bless.
Much love Mike holt. God bless.
Starting Electrical Code and Theory Journeyman class this Fall. Super excited! Thank you for the video Mike!
I'm so excited that you are going to be part of this amazing family. Welcome.
Brian nailed it with “why we need to know as electricians”.
Facts! He sold this video honestly
I recently purchased this. I really enjoyed how they explained everything. I would recommend it. It actually helped me when I took my state test, which I passed. 😊
Please never stop!
Sound volume is a bit low.
Been following the channel for a few years, you're a great communicator, the effort is very appreciated.
Thank you For taught me so much Electricity theory during all this years...thank you MR HOLT
thank u Mike for making this content. your work is helping understand the code a little better...
Thanks for the content Mike Holt.
I am very pleased to see some introductory material being added to the channel! I look forward to watching it all.
This guy is the best!!
Thankyou for making thing better in the world..
That is exactly why I do what I do. Thanks for noticing.
Your enthusiasm is inspiring sir.
I love you guys and so much want you to get excited about learning more. So you can better provide for your family.
Hi Mike! Thank you for sharing what you know. Can you use 2 legs out 3 legs of a 208/230V, 3 phase power source to power a 208/230v 1 phase unit?
Sure.
Even the basics need review: such as VERITASIUM re how electricity (really works)
God bless u Mike
Amazing
Gold!
Saludos desde Cali, Colombia. Buen Mike.😉👍
Did you know that I"m Colombian! I am!
@@MikeHoltNEC wuaw, es qué Gran sorpresa, genial.
Why would the inspector be wrong about bonding the metal poles for the pool? Was it outside the perimeter bond of the pool or were they just insulated by the cups they went into? I thought in one of the examples where the lifeguard was electrocuted it was due to one of the handrails not being bonded. Just trying to understand things a bit better. Thanks for all you do, have learned a lot from you and your team.
Bonding is required for 'fixed' metal parts within 5' not 'metal parts withing 5'.
@@MikeHoltNEC gotcha, thank you Mike
Looking for more explanation
Is there a Spanish version and how can I buy it?
There isn't.
IEC = International ElectroTECHNICAL Commission
Why is, and has, the National Fire Protection Agency engaged in creating codes for the protection of human life from Electrical Shock & Electrocution?
What does that have to do with "Fire Protection"?
Fire is one of the consequences of an electrical accident, when arc faults happen. It's also the risk we are trying to prevent by sizing electrical equipment to have enough conductive mass, to avoid accumulating dangerous temperatures that could cause fires.
Mike are you going to do a 2023 I’m hoping to buy 2023 version
Yep I am!
Okay thank you .when would I be able to purchase?
There are two types of electricians, mechanics that know how, and electricians that know why.
Love it

Rather than call it “Electrical Theory” (eyes glaze over for many), “Electrical Fundamentals” or “Electrical Essentials” conveys as sense of practicality and of application.
thanking god lmfao

Why is it "electrical theory" and not "electrical fact"? :)
Because theory doesn't mean a guess or a hunch. A lot of people confuse theory with hypothesis. A theory is a body of knowledge that explains a family of concepts, and is scientifically proven beyond a reasonable doubt, based on our best understanding in the present day.
A fact is one piece of data on which a theory is based. A theory puts numerous facts together, and builds a model to explain why those facts are true from fundamental principles.
The distinction between theory and practice, is that a lot more factors come in to play in practice, that might not show up in a simple application of the theory. As an example, assuming you have nominal voltage at your service point, and basing your calculations off of it, is an example of theory. Theoretically, you are supposed to have 120V line to neutral, and 240V line to line, on a split-phase service. In practice, the exact voltage at your service point is a moving target, that varies with the loads your neighbors consume throughout the day.
@@carultch Because theory doesn't mean a guess or a hunch.
-It kind of does. It really depends on which subject & semantic definition you use. this has, and is, one of my absolute hatreds of the modern human race: that we use the same word, with no segregative prefix added, for up to DOZENS of different definitions. I literally have a laundry list worth of modern English words we use (even in Trades & Sciences) that area cause of critical confusion, but unless you are in trades/sciences long enough, you won't know what is really trying to be communicated.
A lot of people confuse theory with hypothesis.
-I, and the dictionaries, agree with you that both are different; but one overlaps to the other, unfortunately.
A theory is a body of knowledge that explains a family of concepts, and is scientifically proven beyond a reasonable doubt, based on our best understanding in the present day.
-If that was truly the only definition, then being called a "conspiracy theorists" wouldn't be so bad.
A fact is one piece of data on which a theory is based.
-Correct.
A theory puts numerous facts together, and builds a model to explain why those facts are true from fundamental principles.
-this CAN be correct, too.
The distinction between theory and practice,
-I don't think the OP was drawing a distinction between "theory and practice" but rather "theory and fact".
is that a lot more factors come in to play in practice, that might not show up in a simple application of the theory.

In practice, the exact voltage at your service point is a moving target, that varies with the loads your neighbors consume throughout the day.
-Correct, but that is precisely what the Op is getting at, which is that (as with your example) the "theories" of many features, characteristics, and ACTIONS of "electricity" are FACTUALLY DEMONSTRATIVE & REPEATABLE, so they are no longer "moving targets", but rather fixed targets; therefore, they are FACTS, and not "theory". I truly depreciate that modern English dictionaries of layman use allowed for "theory" to get added the definition you've mentioned for it, when that definition ALWAYS had fit just FINE with the word "fact", even with nuance differences, they should of left it with that word only.
@@MR-nl8xr Do you have a point to all of this? I find your post extremely hard to follow, and the laymen's use of the word theory leads to all kinds of misunderstandings.
The OP asked why it is called electrical theory and not electrical fact. I answered.
@@carultch Do you have a point to all of this?
-If you couldn't read it in everything I wrote, or even the first reply, then there is nothing I (or not sure if anyone) can do to help you.
I find your post extremely hard to follow,
-Most people with reading comprehension, do. At this point, I wouldn't worry about it if I were you.
and the laymen's use of the word theory leads to all kinds of misunderstandings.
-Which is ONE of the many things I brought up in my reply.
The OP asked why it is called electrical theory and not electrical fact. I answered.
-I Understand, but your answer is borderline incorrect, and/or not complete, so I replied to your answer.
HGN :)
This video is a waste of time. Does nothing for anyone.
