Sir i just want to say your channel is a blessing, right now im preparing myself for my journeyman exam and was using mike holts journeyman exam prep book and the box fill and calculations part looked very confusing i appreciate your ability to put this in a simple and meaningful manner this has helped me a lot thank you so much!
Working on my school assignments and have no teacher as I’m working on the road- this has been very handy to help calculate my box fill for the questions at the end of the chapter- thanks.
I appreciate your comments!!! I am glad you liked it!! I am working on building my own work books on Dwelling calculations and also no dwellings. Keep an eye out for them. They should be ready for the summer!!! Thanks for watching!! CM
Thank you!! It is only complicated when people make it complicated. My goal is to show that it is easy as long as you simplify it. Thanks for subscribing!! CM
Thank you. My point is a basic understanding as some people like to make it way harder than it needs to be. Keep a look out for more videos like this!! Thank you for your support!! CM
That is a great way to remember it!! I have never heard it this way. I am going to have to use that one for sure!! Thanks for a great and positive comment!! CM
WHAT IS THE TOTAL VOLUME ALLOWANCE FOR FOR TWO (2) YOKE/STRAP DEVICES INSTALLED IN A BOX WITH 14AWG CONDUCTOR ? Please help me to figure out, Thank you
Craig, for example, if you have #14,#12,#10 romex in the box and each one has internal clamps. Would you only count the internal clamp for #10 ( just like a ground wire) or do you count each all of them?
You need to add a different size for each wire in the box. Unless its a ground. For the ground up to four you only count the largest ground in the box. Do not count splices or the device ground. For the yoke and the clamps it is double the largest wire attached to it per 314.16(B)(4). Hope that helped.
I got a 66 yesterday on my general electrician exam I had a quite a few box fill questions. I thought I did most of them right but great video. There was one though that was 8x8x6 how many number 8’s can fit in that
@@ivanaguilar8820 only after the first 4. So if you have 5 grounding conductors it would count as 1.25. This was changed in 2020 NEC. This video was off the 2017 NEC code. I will be doing an updated version soon!! CM
I am basing my video off the National Electrical Code 2014. This is very interesting as I knew there were some differences but was not aware of this. Honestly I dont understand why they are not counted as they still take up space in the box. Thank you for this info. Learned something new today!! CM
Craig Michaud- Electrical Instructor I have this worksheet I was given asking. What size box is required for twelve #10 THW cooper conductors and ten #12TW copper conductors?
@@rogertorrez1798 Okay all you have to do is go to the table talked about in the video and add all the wires up. For example a #12 is 2.25 x the number of wires and then do the same for the #10. Hope that helps!! CM
love how he just appears out of thin air like a magician and just gets right into it with no annoying intros
Super magical
intors are so 2020

I've watched so many of these videos in preparation of my contractors exam - which, I passed. You're the man, Craig. Thanks.
@@PaulHigginbotham-s4e Congratulations!!! I appreciate your kind words!! CM

My teacher isn't the greatest. Thanks for the additional help. Worked great for me :)
Miguel same
yeah probably the same for the rest of us if we're all here
My teacher spend a combined 5 minutes explaining this and moved on smh. I’m sitting here in lab trying to figure it out myself now, thank you!
You are a great teacher for some reason I understand your breakdown .
This video helped me quicker and better than reading my 3 big ass books from my school.
I appreciate your comments!!! I am glad you liked it!! I am working on building my own work books on Dwelling calculations and also no dwellings. Keep an eye out for them. They should be ready for the summer!!! Thanks for watching!! CM
Great , simple straight forward explanation. thank you!
Thank you! The way it was broken down step by step was super helpful
thank you. ..taking classes in community college and your explanation on the board was very helpful as I struggling to do my assignments
You are the best teacher. My congratulations.
This is a great video. You made box fill super simple. Subscribed!
Very good instructor 👍
Thank you my teacher explained to me very clearly but I just had to refresh my memory. This help a lot
Thank you Craig! You did make the box calculation very clear. Thanks again for sharing the great video! Rick Deboi
Great teacher love how you broken down details.
Thank you!! It is only complicated when people make it complicated. My goal is to show that it is easy as long as you simplify it. Thanks for subscribing!! CM
my instructor didn't explain this well thanks for the help. very useful
Thank you for being such a good teacher.
Thank you very much!! I appreciate your support!! Thank you for watching. CM
Thanks for the video! Great job explaining it, I understood it the first time watching it
Great video really helpful when the teacher isn't around.
Thank you for all these information
easy to understand super simple breakdown 👍
Thank you. My point is a basic understanding as some people like to make it way harder than it needs to be. Keep a look out for more videos like this!! Thank you for your support!! CM
I believe the 2020 calculation on grounds is different now. I believe after 4 meaning the 5th ground you need to add .25 to the fill.
Yes this correct, i was confused because the video is different from my apprenticeship classes. He’s going off older code.
Good job Craig, very helpful video.
This helped me a lot.
Thank you for the explanation about the clamps
Please keep your videos coming
THIS MAN IS BASED AND GOATED AND THE ONLY REASON I GOT LESSON 8'S QUESTION 28
each clamp count as 1 or if you have 4 clamps it counts as still 1?
Count the mounting screws for your devices (yolks) so a switch is “two to mount - two to count” a dryer receptacle is “four to mount - four to count”.
That is a great way to remember it!! I have never heard it this way. I am going to have to use that one for sure!! Thanks for a great and positive comment!! CM
thank you, i been looking for this
thank you for the video, helped me out alot!
Great video.
These videos are great
Very useful, tnx for your time.
thank you so much. its really easy to understand.
Thank you so much for this it is so helpful!
So what if you got more than three gronding conductors entering a junction box. Does it still count as 1 ?
Yes sir!!
WHAT IS THE TOTAL VOLUME ALLOWANCE FOR FOR TWO (2) YOKE/STRAP DEVICES INSTALLED IN A BOX WITH 14AWG CONDUCTOR ?
Please help me to figure out, Thank you
For 2 device yokes it will be 8 cubic inch. 2 x 4 =8. If you need more explanation please email me at sparkyinstructor@gmail.com. CM
thank you
Craig, for example, if you have #14,#12,#10 romex in the box and each one has internal clamps. Would you only count the internal clamp for #10 ( just like a ground wire) or do you count each all of them?
Great I clearly understand now
This is so fucking helpful. You’re the man!
What if there were different size wire going in? What cubic inch number do you use as a multiplier for the yoke and clamps?
You need to add a different size for each wire in the box. Unless its a ground. For the ground up to four you only count the largest ground in the box. Do not count splices or the device ground. For the yoke and the clamps it is double the largest wire attached to it per 314.16(B)(4). Hope that helped.
Excellent thank you
You have to count the wires for the pigtails or no?
no
Do these same calculations apply for a service main or are these only applicable towards jboxes?
What are some examples as internal and external clamps in detail?
Excellent, thanks!
I got a 66 yesterday on my general electrician exam I had a quite a few box fill questions. I thought I did most of them right but great video. There was one though that was 8x8x6 how many number 8’s can fit in that
I believe multiplying the box 8x8x6 = 384
Then take the size for each wire and divide it into the 384. 8 Awg = 3. Equals 128 #8s.
Very very helpful
Your the man
clear and direct!
Doesn’t 4 ground conductors count as 1 and anything after 4 is .25? I could be wrong
@@ivanaguilar8820 only after the first 4. So if you have 5 grounding conductors it would count as 1.25. This was changed in 2020 NEC. This video was off the 2017 NEC code. I will be doing an updated version soon!! CM
@ that makes sense! Thanks for all the vids been learning alot
Any way possible way youcan do a conduit fill video?
Right on Craig
Thank You
So if it’s 3 internal clamps, they count as 1
Yes sir!! CM
@@craigmichaud-electricalins4602 awesome , thanks for quick response!!
My English is not that good but the teacher is very easy to understand
Very helpful!
I thought two wire nuts counted as one? I read through my 2018 Canadian electrical code book and it says to count two wire nuts as one conductor size.
I am basing my video off the National Electrical Code 2014. This is very interesting as I knew there were some differences but was not aware of this. Honestly I dont understand why they are not counted as they still take up space in the box. Thank you for this info. Learned something new today!! CM
what about 3 4/0 and 2/0 ground?
Keep it up please
Great vid thank you
3hp submirsible motor single phase. I need cable size for aluminum. Distance from electric meter is 1000 to 1200 meter.
Good man
This is more understanding than Mike holt
He is the electrical instructor!
Thank you. The book confuses the hell out of me. I knew there had to be something more concise out there.
Still Learning Off This In 2023 🙏🏼
thank you alot
Thanks!
What's in the box!
"WHATS IN THE BOX!"
Very confused, just started my classes.
Give it time!!! If you have any questions please comment and I will help in any way I can. Thanks for watching. CM

I have this worksheet I was given asking. What size box is required for twelve #10 THW cooper conductors and ten #12TW copper conductors?
How would I solve it?^
@@rogertorrez1798 Okay all you have to do is go to the table talked about in the video and add all the wires up. For example a #12 is 2.25 x the number of wires and then do the same for the #10. Hope that helps!! CM
My teacher is good, but not this good lol
Thank you
