Still current as far as the manufacturer is concerned and that is what really counts isn't it?Published in 1997? New standards and a lot more global coordinations between those had changed the rules. That paper is obsolete.
So? Who has said you can't operate at the prime rating? What has the prime rating got to do with sizing a standby generator? If you will refer to the documents, the prime rating is less than the standby rating for the same piece of iron. In fact, one of the examples shows how the different ratings for the same piece of iron line up. Still no overload allowance for the standby rating.My referenced paper had clearly stated that gensets CAN BE operated at their prime rating with the life penalties outlined therein.
Your referenced paper does not say anything different that what I have said.
I have also said the prime rating allows for a 10% overload rating capacity. That does not change the fact that the standby capacity has no overload rating. Evidently you are not reading what I have said.Apperently more than one readers and contributors to this posting seems to read it the saem way or had the same understanding.
