OPTIONAL METHOD, Single Family Service Calculation
Published 2019-06-21
Most Electrical exams will ask to solve a single family service calculation using one of two methods. I am working out of the 2017 National Electrical Code Book.

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!

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.

thanks for the video!!! I have one question, do the refrigerator belongs to the small appliance circuits? it also 1500va?
-
Thank you for a clear instruction and excellent information

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.

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

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

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.
