## 220.88 New Restaurants.

Guy, when you use a rule, you use it as written, includint tables and notes to table. The note to Table 220.88 is as follows: "Note: Add all electrical loads, including both heating and cooling loads, to calculate the total connected load. Select the one demand factor that applies from the table, then multiply the total connected load by this single demand factor." So when you are using Section 220.88 and apply Table 220.88, we then apply note to Table 220.88. Yes, we do include a/c and heat. It doesn't have to make sense, we just have to follow the specific rule. Section 220.61 is contained in Part III of Article 220, it does not apply to any rule contained in Part IV.

Make one of answers 432A instead of 402A works when I ran the numbers.

That's what I had before I took out the a/c. I didn't notice the note to the table...

5. Mike agrees there is an error in the answers. The correct answer should be 441 amps based on 8000 va for lighting-- no 125% should be added to this. Add all the other stuff and you get 105,850 va

105850/240 = 441 amps

There is a note that he wrote that says to see annex D example D3 for continuous loads

The answer for 26 is 656 amps

Thank you. So just a minor typo. It happens.
