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!

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!

Everything just clicked. This is so much simpler than the way it's been explained to me before. Thank you

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 .

If everyone was like you the world would be a better place.

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

As a young one in the trades thank you for what you do. I can only imagine the setup it takes to get these videos out. Keep it up.

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.

Your an excellent instructor love how real you are and simple you make things

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!!

brother, thank you so much. Finally understand how this works. Testing for state exam tomorrow and this clarified so much!

Best voltage drop video on KZfaq

Mr. Craig...you explain so well, I just write it. Thanks a lot.

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.

New subscriber, journeyman electrician...but still have very much to learn. I appreciate you taking the time to put out this info. Very useful.

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.

thank you Sir Craig i'm a huge fan of yours and thank you for your the Voltage drop information to keep us safe

Great explanation, I needed more clarification when studying on my own. Thank you for upload.

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.

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

Thank you very much. Had a long run out and down to a well pump. Your information helped me size the wire correctly. Many thanks!

You rock, I'm in my 3rd year and you made this so much easier than my instructor did !!! Ty buddy 👍👍😉

You saved me! Kudos to you brother may god bless you. Keep doing what you do

Wasnt quite grasping this in school, but this video was a huge help

Craig, Very good video. I was having an issue with this scenario, but you cleared it up for me. Thank you, very much. Keep up the good work!

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!!!!

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

Your videos are so helpful, appreciate ya man 🙏🏼

I haven’t done a vd Calc in a while, thanks for a good refresher!

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

Everything I needed to know in the first minute. Thanks! 😎

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 !!!

Very nice way of teaching i appreciate KZfaq for allowing people like you to help guys like me better understand this topic good job

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!

Thanks, I am studying for my electrician licence and this helped me a lot.

You explained it so perfectly, Thank You.

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 love when there are example problems step by step.... thank u

Shout out to your vids! You helped my boy Derick pass his masters and now he’s a full time baller

Excellent tutorial it's really help me... Thank you Mr Craig.

Great Video with great easy to understand information! Thanks for doing a great job!

Im taking my JM test this week. The way you explain it makes a lot of sense. Thanks. I'm sure this will help a lot during the test

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.

One of the best instructor of all time goat .. would love to have one of your instructor book

Dude thank god you have this channel thank you

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.

Good videos keep them coming man, you're very good at explain things.

You are the best, you make it very easy to understand and remember. Thank you, please keep making more

Thank you for your great teaching! Merry Christmas!

Love your videos my man, helping me out so much

Thanks really helps watched all your video's..

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 clear and concise great video

Excellent job!!! 👍👍👍

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 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.

Great video, this saved me a whole chapter of reading ❤️

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

Thank you so much for what you do man, super helpful

Thank you, very informative and helpful.

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.

Craig. Thanks for the video. Well done.

Respect from Virginia. You Sir will help me pass this (blankety-blank) electrical exam. Liked and Subscribed!

I have a midterm for 4th and final IEC year. This will help me in my exam tomorrow. Thanks.

Excellent video. Thks very much my boss

Thank you so much for your useful lesson

thank you for this video. keep up the good work

Love the content!

Thanks, this was a useful refresher

I passed my journeyman test because of your videos out in Idaho thanks! Got a 75

Craig, as a homeowner do I use the same calculation for various task? I was wondering if I was supplying enough power for my electric 12amp lawn mower I have plugged into my outside 30 amp house outlet. I’m using 70 ft of #10 wire (30amp fuse) for the outlet. I’m plugging in a 100’ and 50’ #12 extension cord to run the entire length and width of my property. Using your calculation, the #10/distance is fine but the #12 wire has too much voltage drop (7.11) compared to the 3.6 allowed. The mower seems to be running fine but does figuring for panel to panel wiring being the same as my outside house outlet ( being enough for a 20 amp terminal box), would I use the same calculation using a #12 extension cord to run my 12 amp mower @ 150’)?

Great content. Helped me a ton!!! Spelling could have been better but we're just simple Elektrisions lol

Beautiful job sir im new to your channel and i already love it thank you for your channel it help so much

Great video 👍

Thanks From India!❤️💙
