Commercial Service Calculation - Deep Dive 2023

This video is a thorough, step-by-step analysis of a commercial service load calc, using a retail store (with restaurant) as an example. A complete, yet concise table format makes it quick and convenient and can be used on virtually any commercial calc.

Great information, as usual. I’m taking my admin test in Washington state next week and your videos are super helpful. For the non-coincidental loads, if the largest motor were not the air conditioning, would you then use the whole 125% demand of the largest motor? Or would the same logic apply that because the motor was already accounted for you take 25% of the largest motor and tack it on at the end?

Glad you like the videos! My instinct is to answer yes to both questions, so perhaps I don't fully understand the distinction you're making.
No matter where the largest motor is in on the service, you want to take 125% of it's value - unless it's the lesser of noncoincident loads; then you would only take 25% of it. That's my understanding of what they have written in 220.60. But this code section is problematic and needs to be revised. So until they fix it, we have to make an educated guess as to their exact intent.
An alternative guess is that they want us to compare the noncoincident loads after taking the motor load at 125%, and then take the larger of the two. This, of course, assumes the motor load is the largest on the service. This is actually the way I personally think noncoincident loads should be treated. But if this is what they intended, their wording is incorrect because they don't even mention anything about the largest motor on the service in 220.60.

Hope that helps answer your question!
