I have always found 220.87 to be...interesting. As we all know, the article 220 calculation based calculations are very very conservative, and then we have 220.87 which only requires 25% beyond the demand data and does not require any additional factor for lack of balance (the 30 day exception method does) or power factor. I am just surprised how close they potentially let us cut it.
