Sizing Dryers and Ranges, Load Calculations
HTML-код

- This video is to help you understand how to size a Dryer and a Range in a single family service calculation.
DRYER
Art. 220.54 States that a dryer must have a minimum demand of 5000 watts or the Nameplate rating which ever is greater.
RANGE
Art. 220.55 States that an electric range must be calculated according to Table 220.55
Note 1 is explained that if you have a range that is over 12kw every 1kw over 12kw must be calculate by 5%.
Example
15kw
-12kw = 3kw
3kw
x.05 = 15%
8000 per 220.55
x1.15 = 9200watts

And also thank you for not talking 1000 mph like mike holt does, I understand the first thing he’s talking about and then I blink and he’s on to explaining the fourth thing 😂
Watching your videos makes me wonder if I really had to spend $700 on an exam prep course. They did calculations in the first week and I was lost. I saw 3 of your videos and understood calculations right away. This was indispensable Thank you Craig
Well thank you!! I guess I really need to work on an online calculation course for people to buy!! You have given me a great idea!! I hope to have something out in the spring!! Thank you for watching!! CM
These load calculation videos sure do help !
Thank you sir
You just helped me get my electrical license
Thank you for simplifying things and not trying to sound like Albert Einstein with everything you say like most of the others, this is truly how people learn efficiently. Thank you! Much respect
13 years in been journeyed out for awhillleeeee. never took care of gettin my A card when I should of, always wanted it never got it. now I've set the goal to get it and have been sitting down studying knocking the dust off and getting ready. your videos have been very helpful in reassessing this files in my brain as I get ready to test. great videos appreciate your videos and your ability to make it simple and to the point in each lesson. good work my guy.
If you had a Patreon I'd donate to you right now! Studying for my SFD license in NC and this series is a godsend. Liked and subscribed - Thank you.
Man I am struggling bad thru this part of the course. I love how you just slow down and make sure it makes sense before jumping to the end. Column C is killing me right now.
Thank you for making this video and helping fellow future electricians.
👏👏👏👏👏👏
Thank you. You make it easy to understand, but more importantly you make it easy to remember!
You’re probably the best so far in RUclips
Missed a section in class and your videos came in clutch to help me catch up, thanks bro!
Clear, and precise...indeed invaluable.
Can you please make some more videos? I think you probably give the best breakdowns on these calculations out of everyone I've seen. Thanks.
thank you sir, you are very good at explaining this calculations man I wish you were my teacher. this videos are really helpful.
Thank you for your kind words!! I try to make these explanation a simple as possible!! Thank you for watching!! CM
Thanks for the video Buddy, I am preparing myself to sit for the Washington DC Master Test. 👍🏽
Good luck on your test!! CM
You are the man!
this is great! I avoided 2 hours of zoom!
Excellent!
you are the best
Thank you I got alittle confused with the percent factor . I will te. Watch this video.
Thank you I am taking notes and will show my professor. He will be exited to watch your teaching method
Thank you for your knowledge. 1. What if your range is gas?
2. What if your water heater is gas?
3. Are the microwave, dishwasher and garbage disposal separate from small appliances or do you add separately or one more to small appliances?
Thank!
So for that range example a 40 amp breaker is needed 😉👍
I'm studying for my residential license with you what other videos should I watch concerning getting my residential license......thanks BROTHER
thanks for your videos! do you have any videos on Water Heater branch circuits? containing branch circuits with ovens and fryers on the same circuit as the water heater?
If you have two appliaces and they are rated at 11,000 watts according to Column C, how would you split that up between the two appliances on a load sheet?
Just subbed
Do you have a video where it shows, note 3 range calculations?
👏👏👏
What number are you adding 15% to, to get 8000 at 7:59
if i understand this correctly.. if i have a for example 9000 watts i have to - minus 8000 watts?
does a range circuit require a neutral?
Hi Craig I think there is un intentional miscalculation, just to make sour if I am in the right direction ? 15,000kw -12,000kw=3kw times 5 .
times 15%. So 15 to 100 =1.5 not 1.15 and then the answer would be 8000 times 1.5 if I am right,
No it is 15% or as I do it 1.15 ×8000. It is just 15%. CM
At the top of this you the best great NEC instructor
wheres the multi ranges video sir?
how are you getting to 8000?
do you still have to use 5k for dryer if it's gas?
@Tom Garbo I'm building the apartment complex. Installing gas, not running electric.
Okay sorry for being lost but somewhere in a practice exam the additional 5% per 1000 KW was added to 12,000 instead of 8,000. What is going on there? I is there a scenario where this is done
The 5%is added to the 8000va. Never to the 12Kva. You subtract the the from the over 12kw add the 5% to the 8000 as I explained!! I have a video on using 220.55 this will explain it. CM
@@craigmichaud-electricalins4602 thank you for the reply I will amend my notes
What if you don’t have a range but a separate cooktop and built in oven? Would these be considered fixed appliances?
Yes you would use the combination of the two and then find where you stand on the table. Great question!! CM
Part 2 of that question is No you still use the range line only on that. it is not a fixed appliance!! CM
Thank you for the quick response. I really enjoy and appreciate your videos.
No comment on gas dryers and ranges? :/
Very knowledgeable but please smile
Smile please
Why can't you just multiply 8,000 by 15 % . Why do u have to break it down to 1.15. because I did the math and it gives me a different number of multiply 8,000 × 15%
