I am struggling with the statement in 700.17 "Unless both ....are kept lighted."
The entire building is being put onto generator and night lights are not requested. If I did put in battery powered lights, they would never come on - or would only come on for the few seconds while the generator was starting. What am I missing here? Am I required to have night lights in order to put the whole building on generator? This is a partially attended greenhouse facility. But I am curious in general due to the wording.
If the building had partial generator power, then either I would provide a GTD device for emergency lighting or I would provide ballasts or emergency heads. But if the whole building is on generator, there is no panel to get a signal telling the fixtures that the building is on emergency. So any provided emergency fixtures would seldom be on and then only for seconds.
So where is the exclusion to "are kept lighted"?
