WHOLY SH**!!!!!!!! finally a straight forward easy to understand explanation!!!!! I can not thank you enough, I spent 5 hours on my own trying to figure it out. I flew through the rest of my homework in minutes. THANK YOU
Your video is the best explanation I have seen for voltage drop in my 48 years of experience. Anyone can read all about it, but a video like yours explains it best for future electricians. Good job!
I recall an instructor going through this formula many years ago. However in an adult evening class he kind of rushed through it in only a week which was two nights . That was before the internet . Today I am glad teachers like you bring the important topics like this for re-learning to learn . Thanks .
exactly!! and I hated that. because of the "know it all" mentality of electricians, a teacher would run through crap and be like, "well I know you guys all know this, so we're just going to run through this really quick, is there anyone that needs to slow down?" REALLY!?!?! like youre REALLY gonnas raise your hand and tell the class that youre gonna slow them the hell down! thats going to ALSO cause unneeded stress upon the guy learning!! I HATED THAT!! HATED!! TOTALLY HATED THAT!!
@@LTVoyager Nothing Changes. Cooper and Copper have the same Konstant anyway.. LOL Another thing i noticed was the first example was 4AWG and the second was 2AWG since he changed the voltage from 240 to 120.
You saved me from yet another sleepless night trying to figure out which of my contractors is right about my wire size for my generator. Sorry about the other SUPER LONG COMMENT but I thought it would be worth laying out my math showing you how you helped me learn this tonight. I know NOTHING about electricity so this was perfect sir!
With out this i would not have passed my test.this is the one thing i had trouble with.it took majority of my points.so glad i ran into your vedio.thanks so much.
In its category/ context, This could be THE most helpful video on the internet. Thank you Genuinely SO much. Sincerely appreciate it! Im currently buried in ET school, and you're saving my bacon.
I could not agree more sir! This saved me hundreds of $$$$ on my 160' generator wire run that I am buying in 2 days. Absolutly amazing. $20 tip to this gentleman!
You are the best teacher I have found for my electrical answers! Please keep making them. I value your time and energy doing these on the whiteboard. I have learned more from you than my teachers!!
Great info dude, have a 343 run at 240 volts 200 amps just quiclky came up with 250 kcmil at 7.01 voltage drop bec because 4/0 was at 8.3 Thanks a lot for you lecture/reminder
So, im studing for my masters, and its been awhile since i studied for my journeymans, and i dont think that i ever fully understud the whole sizing of wire when voltage drop is given, im using a mike holtz study book and kind of jumping around, i was totally lost on how to calculate until i watched this video not i fully understand, so when i have one of these questions come up ill be thinking about you man, hats off to you, and thanks for helping further my career. God bless
Many thanks Im in class early getting ready to take my midterm exam. This voltage drop video really helped break it down. Please alert me of any electrical videos you have. Thanks.
8:49 minute mark "cooper" equals copper. Which is an excellent conductor.Great video and commentary. I'm going with a 25' ft length because of. Thanks.
Thanks I need to revisit this exercises once in a while so I don't forget , I'm getting old and memory not always good , but on the back of my mind I know there is always someone great electrician helping others Tx
I would give you 100000000 LIKE for that video!! I am electrician came from overseas. I have been working electrician in the USA for six years. Have SO MUCH difficulty of Decimal. Now,you Craig got me how to Calculate the voltage drop SO EASLY !! THANK YOUUUUUUUUUU!!! Please, upload more videos like that !!!
I was in class last night and I don't know if I didn't get it or if my teacher was struggling to find a way to teach it but I needed this explanation thank you so much!
This is awesome my teacher didn't explain this to well and I was lost when he explained it. I'm a visual learner and this made it super simple to understand!! I'm taking my journeymen exam soon and this is great great practice!! Thank you so much!!!!
I liked watching your video and it reminded me of my electricity classes at the South Florida Institute of Technology in Miami, great career in the United States, thanks for your channel
Very nice and clear explanation of voltage drop and wire size calculation. In large homes I have a nearly 6000 sq feet. Some of the voltage drops for a 15 amp branch circuit of at least when measured from the ideal circuit analyzer suggests a drop of 9-11percent that’s for the end receptacles on that circuit even though the first receptacle has. Voltage drop of 3.5 percent. I suspect this is a common problem when electricians and construction companies are fitting branch circuits namely that they meet the code for the first receptacle but not all the receptacles. Short of rewiring the circuit is there any external means to bring the voltage up on those end receptacles - most residential equipment could tolerate a drop of that nature but obviously long- term it’s not going to do that equipment any favors.
In my opinion code should require 20 amp circuits on all as a minimum on plugin recpticals; witch requers a minum 12 gauge wire witch should have less Voltage drop! A 15 amp breaker can't have a wire less than 14 awg but THERE'S nothing in the code that says you can't use 12 gauge or heavier on a 15 amp Breaker. Breakers at least standard breakers job is to protect the wiring not what's connected to it like a lamp pluged in to a plugin recptical, Etcetera, Etcetera.
Great explanation Craig. I just needed to calculate the conductor size for a shed building that is a total of 320 feet from the supply panel. Want to have a total of ampacity of 50A on a 240V single phase system. I came up with #2 THWN Copper for my conductors. Thanks for the refresher.
Thank you very much, I wanted to find this type of information or explanation, and the truth . . . You did open my eyes, because it is very important to learn the electrical calculations to feel that one I truly advancing in the world of the electrical power 💪😊👍
Very good video Sir. Taking another journeyman test for another state and had to brush up on some stuff I don’t normally use and this was just what I was looking for. Thank you Sir.
Awesome video thank you so much!!!!! Ed specially the voltage permitted I always used 3 percent didn’t know bigger voltage bigger voltage drop potential
Very good job Craig, this is the type of videos that I was searching , keep updated us, I will take my test in a few weeks,I definitely will keep watching your videos thank you
Hello Craig. I am admiring your classes!!! THASNK YOU!! I would like to discuss or make class(s) as playlist for if we have a bit on a new Construction "House" single or two history . What we have/should do to calculate all we need from the Service conductors, feeder conductors,.how many outlets we need, including calculations of voltage drops ,appliance, etc. Please make that kid that Video. Thank you!!
Thanks for the wealth of knowledge. The size of wire from pg&e of single phase 220v to my building a as bout 180 ft, what size of wire shall I choose to ensure ac, water pump works? 4/0 or 2/0?
Brother you wrote "cooper" twice and "condutor" once. Besides having to watch this on 2x speed, my attention to detail is what saves my life and prevents return trips to anything I've touched. Please pay attention man, Godspeed.
This is a great channel and video, much simpler way to do it than how I was taught in trade school. Let's say the circular mils required is 68,000 - would I be correct in saying that the #2 which is 66,360CM is too small and I'd have to upsize it to #1 awg? Basically I have to have a wire that is the same size or large than the CM required right?
WHOLY SH**!!!!!!!! finally a straight forward easy to understand explanation!!!!! I can not thank you enough, I spent 5 hours on my own trying to figure it out. I flew through the rest of my homework in minutes. THANK YOU

me in class with the same problem as a young adult and teacher rushing thru it haha come on Mills slow down XD
But what if we don’t have cooper conductors, but have copper instead? 😂
@@LTVoyager Nothing Changes. Cooper and Copper have the same Konstant anyway.. LOL Another thing i noticed was the first example was 4AWG and the second was 2AWG since he changed the voltage from 240 to 120.
If everyone was like you the world would be a better place.
Everything just clicked. This is so much simpler than the way it's been explained to me before. Thank you

Amen 2 that !
Going for my master's license in 6 days. Thanks for the brush up on voltage drop. "#2 Cooper Conductor"
How did the test go? Always remember, Cooper and Copper have the same Konstant 😅
You’re providing a great service for someone like myself who is just starting the trade. Thank you for taking the time to make these.
Im a first year apprentice and thiss just helped me finish my Voltage Drop and wire size calculating homework, you are a god sent human

Good Video, got a midterm coming up for sure helped
Wasnt quite grasping this in school, but this video was a huge help
Great video Craig. Thank you. You're the best.
thank you Sir Craig i'm a huge fan of yours
and thank you for your the Voltage drop information to keep us safe
Beautiful job sir im new to your channel and i already love it thank you for your channel it help so much
Awesome video thank you so much!!!!! Ed specially the voltage permitted I always used 3 percent didn’t know bigger voltage bigger voltage drop potential
the 3.6 was such a curve ball. i made the mistake to divide by 3% so many times. thanks so much!
Very good job Craig, this is the type of videos that I was searching , keep updated us, I will take my test in a few weeks,I definitely will keep watching your videos thank you
Thanks really helps watched all your video's..

best explanation ever ! keep doing this !
Great content! Thank you for your time.
Please do more vudeos.. your doing a great job.. thanks
Thank you so much for what you do man, super helpful
Easy to understand and follow.
Kindly put a video of how to calculate voltage drop when given the size of wire,the distance between the wire,current and the resistance .please!
You the best brother

yes, the larger the kcmils the less the voltage drop with the given amp draw
Excellent video. Thks very much my boss
very good explanation, easy to understand
Thank you Sr very helpful 👍
Craig. Thanks for the video. Well done.
