Hello!

I am studying for my architect exam and want to find a chart/outline of how to calculate the electrical load for a small office building.......
I have an excel spreadsheet from the internet with columns to enter the description and Va loads......how do I count and assign the various lighting and receptacles of the office.

This is defined in article 220 of the NEC with examples in the back of the book.
If you have a copy of the handbook there is additional commentary.
