Yep, the exam will tell you whether to use the Optional or Standard Method for the question. In the event it doesn't specify, you would need to go with whichever method gives you the lowest size service (usually the Optional Method). This assumes the question is asking for the minimum size, which is typical.
It depends on your situation. I would generally recommend the optional method for most applications. It is quicker, easier, and doesn't require as much detailed data collection. However, the standard method is more precise. So, if you are using the optional method, and end up close to a service size limit (say, you calculate185 amps), then it would be good to run it through the standard method also. You don't want to cut it too close on a 200 amp service. ALWAYS leave plenty of wiggle room, if you can. Keep in mind, that there are rare occasions where a standard calc actually comes in lower than an optional calc. Usually only on tiny buildings.
@@jirehelectric I'm working on getting the tables available for download. I'm putting together a website in my spare time and unfortunately it's taking a little longer than I'd hoped. I'll send out a notification when they are ready. Sorry for the wait!
@@simply.electrical That would be great. I just got my electrical contractor license and I have been working on sizing a 6 dwellings units service plus house, the square footage differs from each other and your videos have helped a lot so you explain more clearly that others on you tube and because sometimes there is no time to go all the way to the process a template would help a lot. Thanks for your hard work. 👏 Sorry for my English I am second English speaker.
At the moment, I don't have a program created, just the videos. I'm working on making the tables available for download, but I haven't had time to finish it yet. Thanks for expressing interest. This will help prod me to get on it!
Yep. The clothes washer load is handled by the Laundry load @ 1500VA (Left Column, 3rd Row). We are required to use a minimum of 1500VA per laundry circuit. I have an in-depth explanation of this here at about the 11:00 mark: th-cam.com/video/CzIiZwBkNNU/w-d-xo.html
Great question! I'm in the process of creating a fillable spreadsheet format. Once they are available, I'll put links in the description. However, it may be a while before I have them completed as it will take some time and I'll be working on them as I have a chance. Sorry for the wait!
The formula for calculating amps for a 3-phase load is: Watts/(Volts x 1.732) = Amps Remember, you have to multiply the volts by the square root of 3 when calculating these 3-phase loads. Hope this helps!
Question, I don’t know which stander method we can use in the test exam (state Administration ) ?
I got the answer through the chat. Thanks

So which method you better recommend. Thank you.

How can I get both templates (optional & standar methods) for single dwelling and multiple dwellings units calculation spreadsheet to compare Thanks

Hello, how much for the program?

It looks like you didn’t include 1300 VA for the “clothes washer” in the first example. Was this intentional?
Yep. The clothes washer load is handled by the Laundry load @ 1500VA (Left Column, 3rd Row). We are required to use a minimum of 1500VA per laundry circuit.
I have an in-depth explanation of this here at about the 11:00 mark:

is it possible to gain access to these files? can i buy them as part of a course?

How did you get 640 A amps? What’s the formula?
The formula for calculating amps for a 3-phase load is:
Watts/(Volts x 1.732) = Amps
Remember, you have to multiply the volts by the square root of 3 when calculating these 3-phase loads. Hope this helps!
