OPTIONAL METHOD, Single Family Service Calculation

[@TheUlesifah701]

Hello from North Dakota Craig, just wanted to drop a line and thank you for your videos. I recently discovered and watched your videos on service calcs and voltage drop for a refresher the night before I took my journeyman exam last week. They were a huge help and im happy to report that I passed my test. Thanks again for the straight forward great videos buddy!

[@erikdaelectrician6102]

We need more calculation videos. You’re my fav😢

[@emilyyang7087]

Great instructional video, Craig. I've learned from your channel, subscribing!

[@oscar27ization]

Thank you Craig you’re a career saver. One of the best in KZbin so far

[@craigmichaud-electricalins4602]

You are to kind. I just want to make it as simple as possible because I use them for my classes and Code prep courses. Thank you for watching!! CM

[@PaulGiles-y9j]

hey Craig thanks for all the instructional videos! ive had about 7 years on the job working in commercial/industrial electric but this was probably 20 years ago. ive got into building houses now and wanted to get my journeyman liscence so i could wire my own houses. your videos help greatly while studying the codebook to get ready for the test! thanks for everything you are doing. looking forward to wathching the rest of your videos while i prepare for the exam

[@VinceYoungIsTheBest]

I love your videos Craig. I watched some of them many times. I just went this week and took my TN exam and passed it. You've helped a lot.

[@austintittle5046]

I appreciate the time you put into this. Helps me alot. Ty

I liked the way you teach and show gratitude for success of you channel ! Thanks Craig

[@icevariable9600]

I really appreciate your videos. They are incredibly helpful. I hope you keep them up.

[@artemiosalinas8100]

I'm currently studying for my exam in Idaho and your videos have been very helpful. Only thing I would ask is you say to follow the code book could you show us like you did in other videos. I'm more of a visual learner when it comes to the code book, and it would be a great help. Thank you for all you do.

I'm taking my master's electrical exam Thursday & you've been a huge help! Thank you

Good luck!!! I am glad I could help. Keep me posted!! CM

[@dontefarris4429]

@@craigmichaud-electricalins4602 hey what's up man, unfortunately I couldn't pull it off this time (Philadelphia). For some reason I feel like the majority of everything that was taught in my prep class had nothing to do with the exam, not many demand loads questions either. I'm going to take a different approach and attack it again next week hopefully. If you have any tips please share. Thank you.

[@craigmichaud-electricalins4602]

Well Head up!! Not everyone passes the first time. As an exam perp instructor its hard to go over everything that could possibly be on the exam. Its really more of navigating the code than anything else. I would like to know what you were taught in your class compared to what was on your exam. Please email me at [e-mail]. Enjoy your weekend and start prepping for the next one!! CM

[@WiliamBennettwildarbennett]

Thank you for a clear instruction and excellent information

[@janmichaeltan664]

thanks for the video!!! I have one question, do the refrigerator belongs to the small appliance circuits? it also 1500va?

[@heroknaderi]

Very helpful. and based on the calculation you did in this video i see 80 amps is good enought.😀

[@CleberLRamos]

very good your video. congratulations

[@daramzd7949]

Thanks for the video. I've a 3.5ton AC and I see you used 4000watts for your video (house total size is 262 meter sq). How do I get my calculations for the Air Conditioner wattage as it is not written on the plate?

[@lemuelms]

Hi Craig, I watch your videos and I was following your line method. Does receptacles are included in the general lighting or should be calculated based on the number of outlets x180va. Am building a barn of 200 sqft.

[@stevenprebeg]

Thanks for the videos ! I find them helpful. I have one question that came up a few times on a practice exam …. I was able to find the VA calculations , but some questions were asking the minimum amount of 2-wire , 15 amp branch circuits when we know the square footage of the building .. I’m not sure how to figure that out if we know the total calculated load.

[@emilyyang7087]

Hi Craig, the example calculated 18571 VA for the load. In order to calculate Amperage, 18571 VA is divided by 120 V or 240 V? Do you recommend optional method or standard method? Thank you for helping the community!

[@mundoelectricousa7547]

Excelent

[@clydebage3466]

so happy and need more explanation

[@jstevens501]

can you use the optional method for 2 units? like an ADU? cant find any info on that. Multi family is 3 or more units.

[@albertoabreu2417]

Hi! Do you have any videos about kitchen optional calculation method?

[@craigmichaud-electricalins4602]

Not at the moment. I hope to in the future just not sure as of when. Thanks. CM

[@pvdesigncourses730]

Craig, I love your videos. I’m really stuck on 220.83 (calculating whether new loads can be added to an existing service or feeder) and I don’t think you’ve touched on it. Basically I’m trying to figure if you need to be including 100% of existing, non coincident HVAC load in your 220.83(A) calculation. It is really odd that it isn’t explicitly mentioned the way it is in 220.82 and 220.84.

[@Fab24hdumans]

Just found out your videos, really informative, thank you for the time you spent on this, truly appreciated. Question, what is the reason why choosing Optional method (Part IV) instead of standard method (Part III)? Thank you

[@craigmichaud-electricalins4602]

It was explained to me that it is based on the location. I believe the standard method is used most common but something I plan on doing is a video on the same dwelling and see what we come up with using both methods. Thank you for the video idea. Thanks for the support. CM

[@Fab24hdumans]

Craig Michaud- Electrical Instructor “location”? Like building a tree house or a boathouse? I am kidding of course . Kind of vague “location”

[@SmartLifeSolutionsWork]

Love your videos, can you do residential load calculation multi family dwelling units that's the on I have trouble with.

[@craigmichaud-electricalins4602]

Thank you for watching my video. I am working on all aspects of a load calculation and in the future I will be doing videos for all including Multi family and Non dwelling. It takes time to build them so that they are very understandable. Keep an eye out as I do videos every week. Thanks again. CM

[@hyagosilveira987]

Hey Craig quick question just to clear things up. If you’re doing the optional or standard method, do you need to know the name plate ratings before doing any calculations ? For example when you’re doing a rough, should the home owner already know the appliances he or she will have? Therefore you can get the specs

[@pabloluna7881]

This was my thought exactly.You don't know what the name plate is at this point.

[@drawingtime2589]

Ok the multiplier (3) is from 220.12 General Lighting Loads multiplied by the square ft. Where are you getting the small appliance and laundry numbers from? Thanks

[@blandonkennya]

220.82 B(2) 1500 volt amperes for each 2-wire, 20 ampere small appliance branch circuit and each laundry branch circuit covered in 210.11 (C)(1) and (C)(2)

[@jddavis0490]

where are you finding the first 10,000VA to be at 100% demand factor for this problem? I'm confused because because where I find this demand factor rule, it is in Table 220.44, but my understanding was that this table is for "non-dwelling" receptacle loads. Are appliances non-dwelling receptacle loads?

[@beeps7]

Table 220.44 is used for the standard method. This video is explaining the optional method. The 10,000 is found in article 220.82 (B)
