I have a customer that wants everything covered by a generator. This is a medical office building with no existing generator. The service is a 120/208V, 800A, 3 ph, 4 wire service. My question is do I have to size the generator for the entire 800A capacity or can I size it per the know load (several years of electric bills)? If the know load is 200A and I size my generator at 85kw (300A) is this a code violation because it isn't sized for the 800A service? Also, because this is a MOB, if I put in a generator am I opening the door to issues of "Emergency" generator verses "Standby" generator?
