Celtic,
Its all formula driven and common sense - an espresso mixed with steamed milk or a load calc on an bunch of electrical circuits. None of it is rocket science.

convienence outlet load
I'm estimating the load for a commercial suit for the owner of the facility. I know how to figure the lighting, motor and equipment loads, but I have 50 duplex recepticals (120v) scattered through out the facility. How do you figure these into the load caculations? I was told that you take 100% of the first 10kva and 50% of any thereafter. What's the starting point, is each receptical considered a 20amp(120v) load, or do I have to figure the number of 20amp circuits used and they are the 20a(120v) load?
Whats the formula?

220.14.(I)(K) Figures a receptacle at 180 va per strap (duplex receptacles).
220.44 Receptacle loads - other than dwelling loads. allows a 50% deduct at 10,000va. So 10,000/180 va = 55 receptacles. Receptacle 56 can be figured at 90 va.
