Table 220.12. Which of these are considered continuous? Is there some place in the NEC that tells me? I know from doing problems that Banks and Office buildings are. But I don't know where in the NEC I can find this. What else? Does it depend on the situation? I know that the definition is anything that runs for 3hrs or more at a time. But you are not always given that detail in a problem, but still need to apply the 1.25.
