My man, you were instrumental in my passing my journeyman's test. Now it's been two years and on to the masters. Thanks for all your help, cheers from Texas.
I’m going to vvc and your videos are more precise than any class I ever had . I thank you . This will help me get through my calculations at schools . Thank you
Thanks Craig. I'm a first year student who loves the code. I am studying 2nd year already to gain an advantage and your video had added understanding to a pertinent area in electrical curriculum. Keep it up.
I’m an instructor in San Diego if you just drop in as I did you won’t know what to do but if you guid them to the first section where this all starts there understanding will increase, good job
Hi Craig, this video is simple and straight the point. I like the use of the line method example, where can I find further readings on the line method?
Thank you so much!! I am working on putting a course together with worksheets and deeper explanations on how to calculate services!! Keep an eye out as things will be rolling out in the next few months!! Thank you for your support!! CM
Thank you so much for your support!! You have no idea how much this will help my channel. Please check out my next video that I will be releasing and I will give you a Shout out!!! Let me know what you want to see more of and I will see what I can do to help!!! Thanks again!!! CM
@@craigmichaud-electricalins4602 Very cool, you are most welcome! Your channel has been a huge blessing. I am halfway through year 3 of my apprenticeship so I can definitely come up with some requests along the way!
hi Graig.can you do a video aboutcalculation a subpanel inn residencial because people put large subpanel in the house whith any calculation.thankyou for you videos.casanova EC
Small correction. A basement that is finished vs unfinished is irrelevant. If it is adaptable for future use, you have to count it per NEC 220.12. An example would be unfinished basement with 8 foot ceilings would count since you could turn it into a living space later. A crawl space would not count. The building department has the final say on what is deemed livable space. (At what height does it count).
I'm sure someone pointed out to you that VA is not the same as watts in many situations. For a resistive load it should be, for an inductive or capacitive load it can be different based on the power factor. I won't get into power factor correction.
Thank you for the videos Craig - very helpful. I took my admin test recently and half of the questions were about duplex calcs. It seems there isn’t any info out there on how to calculate it and the code book is pretty vague. Would you mind going over this? Thank you,
ill be testing for my license at the end of this month (second try) i really need help with PF (power factor) calculations i have the formula., but still struggle any vids on that? thank you for this vid it helped a lot the line method was new for me but seems to have stuck in my brain a bit better
Sorry no videos on power factor. Maybe in the future!! I know that won’t help you at this moment but good luck don’t focus to much on the questions but you got this!! CM
very informative. I am currently a student. I was under the impression the bathroom was supposed to have its own circuit, is that not included when when calculating general load.
I live in a 1625 sq ft villa in Florida. The lighting load is a fraction of what it once was after a renovation. The existing 1992 service is 125 amps with 20 breaker spaces. All high hats and table lamps were re-lamped LED. 65 watt equiv R40 lamps use about 11 VA. LED's have a fraction of the incandescent lamp consumption. One can't even buy incandescent any more. Can the lighting load be amended in new construction or a renovation to take advantage of the lower consumption? I wonder if NEC will ever recognize this? Even my outdoor 300 watt floods are LED (23 watt).
What’s the point of taking the 3000 VA and putting it back in at the end I’m sorry I’m just trying to get the full understanding of that it kind of threw me off
Can someone guide me in the right direction...I am not an electrician, and I don't know those codes your talking about. My dads friend is an electrician and he added recessed lighting in my house, but I forgot to put that in the building permit along with the other work that was completed (There was a lot of work done on the house, plumbing, electric, ac, floors, cabinets, almost everything was updated). So now I am doing some more renovations to finish my house renovations, and I wanted to add the lighting in the building permit along with the other work I will be doing (I know I was supposed to get a building permit before I got the work done but I forgot to add it the first time and here we are). I was asked for an electrical calculation load when I applied for the building permit... Is that something I can do myself figuring out on CZcams or do I need an electrician?
I recommended you talk to an electrician. What I have here is to teach students to complete a load calculation in a bunch of video's. This is just a small part of it. This would be the most accurate as they will see what is in your home to add to the calculation. CM
Thank you for your question! In 220 it states that the First 3000va from the total of Line 1-3 and then multiple the remainder by 35%. Once you get the demand the you add that 3000va which is your 100% demand to the 35%. That then is your total general lighting load. I hope that answers your question. Thank you for watching!! CM
@@craigmichaud-electricalins4602 ok thanks. Also if you have time one more question. When is the reference 220.82 (b) used? It talks about the first 10kva at 100% and the remainder at 40. Is it talking about the total connected load like all appliances plus general lighting?
@@lanewesner763 That is used when calculating an Other Than Dwelling calculation. It is used for commercial buildings. I will be doing multi-family dwellings and also commercial calculations in the future. I am also working on creating workbooks for the different types of calculations with an explanation and step by step process. I hope to have them completed for the summer. Keep an eye out for the links to them in the coming months. Thanks for your questions. CM
Thank you for your comment. So the 3000 is the VA that we take at 100%. So after you find your total VA by adding Lines 1-3. You minus the first 3000 then you multiply the remainder by 35% To find line 9 You take the first 3000 and add it back to the answer from line 8. As far as taking a class I am in Connecticut and at the moment I an only doing a license prep class. I am in the process of creating an online line course(s) for people who are not in the area. Once I get this completed I will certainly let you know so you can check it out. Thank you for subscribing and I will be posting more videos in the next few weeks. CM
You are the most straight forward of all the other instructors. The best I’ve seen
Yes sir, I thank you for your knowledge and expertise of electrical code.
My man, you were instrumental in my passing my journeyman's test. Now it's been two years and on to the masters. Thanks for all your help, cheers from Texas.

I love your way of teaching simple and straightforward. Thank you god bless u.
Thanks Craig. I'm a first year student who loves the code. I am studying 2nd year already to gain an advantage and your video had added understanding to a pertinent area in electrical curriculum. Keep it up.
Scott, how’s the field going for you?
Thanks for taking the timeout to creating a video where people in the electrical field can learn this stuff. I do appreciate you thanks alot
Just came on board, love the video very calm and direct great job!!
Thanks for explaining and breaking it down. I really appreciate all of your videos they’re very informative.
Thank you for making these videos. Ive been doing electrical work for 2 years and i am now working on my license, You've been a real help.
Thank you for your support! CM
Quick question how u working on your license don’t you need few more years?
I am in trade school for electrical and this information is golden thank you
thanks a lot to be so simple and clear GOD BLESS YOU FOR YOU DEDICATION FOR OTHERS.
Best way I've seen it broken down so far!
Freshing up for my masters test love the video!!!
Thanks for this video Craig. I'm brushing up on my math and calculations to take my state electrical test.
That is awesome!! What state my friend?? Good luck and please let me know when you Pass OFFICIALLY!!! CM

Where do you Teach? Your delivery is Incredible.
Great thank you
acording what point in nec 2014 you add again the 3000 in the end ? you are excellent teacher
Make it lot easier than mike holtz lol
Mike Holtz has been a little hard on the beaver lately.
For sure,,!!!
I didn't understand why we missed L6 AND L7, And why we add 3000 at the end for L9?
Thanks, sir... your channel is useful
hi Graig.can you do a video aboutcalculation a subpanel inn residencial because people put large subpanel in the house whith any calculation.thankyou for you videos.casanova EC

Hey, you should make a video on how to read the book or like how use the index.
You are badass, thank you
Thanks

thank you for this video. do you say VA is the same as watts for simplicity? as they are not the same.
On line 9 why did you add the 3,000 back into the general?
very informative. I am currently a student. I was under the impression the bathroom was supposed to have its own circuit, is that not included when when calculating general load.
THAT WAS REALLY GOOD ,BUT WHERE DO I FIND WHERE YOU ADD THE 3000 AT THE END
It was “eliminated” in line 5 just to get the remainder used to derate. It was “subtracted” so it needed to be added back in afterwards.
Nice work...been dodging the math part of electrical formulas..lol..but hey💥⚡
Are there any different things to do on 2020 code book ?
Why do you have to add the 3000VA on line 9? What is the 3000VA your adding?
He is putting back the 3000va that he took out at 100% in L5
I live in a 1625 sq ft villa in Florida. The lighting load is a fraction of what it once was after a renovation. The existing 1992 service is 125 amps with 20 breaker spaces. All high hats and table lamps were re-lamped LED. 65 watt equiv R40 lamps use about 11 VA. LED's have a fraction of the incandescent lamp consumption. One can't even buy incandescent any more.

Even my outdoor 300 watt floods are LED (23 watt).
220.11(c)(2) what code book is that meaning year of NEC? Laundry circuits?
What about a garage you plan to use as a workshop (table saw, dust collection, etc)?
Do you have a video on filling out a non residential load sheet? ie; workshop or detached outbuilding on separate meter and enclosure.
Where does the 3000 from line 9 come from?
After I get the feeder demand. How do I know what size amprage for the service?
If you look in my playlists I have one for service calculations all broken down! CM
@@craigmichaud-electricalins4602 Thx. Will def get to it eventually.
Great video! May I recommend a better mic and lighting setup?
What’s the point of taking the 3000 VA and putting it back in at the end I’m sorry I’m just trying to get the full understanding of that it kind of threw me off
"The first 3000 is at 100%" You remove it so you don't reduce it when you do your lighting demand factoring. Then you put it back.
Look up Demand Factor. This will bring it home for you.
It did help but I want to know what you did on the other two lines?
they are not relevant as the calculation did not exceed 117,000va. so I did not have a remainder to multiply by 25%. CM
are these videos still pertinent with 2020 NEC code book ?
Yes they are! The real change was made in the non dwelling part of 220.12. CM
Can someone guide me in the right direction...I am not an electrician, and I don't know those codes your talking about.

How would you find it with a EV charger 60amps
Does general lighting means illuminating, if so why is small appliances included?
Nope has to do with demand for sizing an electrical service!CM
@@craigmichaud-electricalins4602 the term threw me off, thanks much
Hello Mr. Michaud
please what's the name of the book you use in the video, can i get more book enlighten about house wiring calculation
Hey craig, I’m trying to figure out why you added 3k VA in line 9. What am I not understanding? Thank you!
Actually I just figured it out. Thank you so much for your videos craig!
Why did it get added? I’ve been trying to figure out
Please explain why you add 3000va back into it....???????
What if you a wiring a spec home and it has a basement that could be finished in future by whoever buys the house
Hi i like your video
Why didnt you include a bathroom circuit ?
It is not required for a service calculation. It’s all laid out in article 220 of the NEC. CM
These are great videos. Do you have a printout?
No but have been working on a workbook!! It’s a work in progress!! CM
@@craigmichaud-electricalins4602 I got a test coming up in August. You should put something together. The simplicity is well worth the cost!
what about table 220.12 when solving lighting loads for hospitals
That falls under the "nondwelling" and I have yet to do videos for nondwellings. It is on the list of video's for this year. CM
Great video question where did the 3000 come from in line 9? Also is there anyway I can sign up for your class I’m in the Philadelphia area
Craig Michaud- Electrical Instructor
Thank you for your comment. So the 3000 is the VA that we take at 100%. So after you find your total VA by adding Lines 1-3. You minus the first 3000 then you multiply the remainder by 35% To find line 9 You take the first 3000 and add it back to the answer from line 8.

Okay I see why you put the 3000va back you purposely skipped a step and then came back to it
Why we add 35%?? Please explain me.
