I recently have taken my electrical journeyman's test (and passed thanks to Mike's book's) and ran into a question on the test I couldn't find in the code on panelboards. The question was, Can a 200 amp panel board supply a 200 amp load? I couldn't find anything in the code that was against it so I answered yes. There is no test review in Alaska so I don't know if I got it right or wrong. I can't see any reason why you would, but can you?

Re: panelboard loading
Your guess was correct. You may load all overcurrent devices to 100% of non-continuous load. Another way to look at it is to add all of your continuous loads at 125% and your non-continuous loads at 100%.
I am getting ready to go on vacation and away from my computer so someone else will have to give you the referances.

Re: panelboard loading
As I understand it, a standard breaker can be loaded up to 100% non-continuous (less than 3 hours) or 80% continuous.
There are larger breakers that are rated 100% continuous, one that I have worked with is a Square D 3000 amp breaker.
