Gentlemen- I respectfully remind you that we are talking about the ampere rating and horspower rating of the disconnect for air conditioning equipment in Part H of Article 440 and more specifically 440.12(A)(1) talks about the ampere rating and 440.12(A)(2) talks about the horsepower rating. Now it's a case of both not either or when we size the disconnect. The reference in 440.12(A)(2) for calculating the horsepower sends us back to Article 430 and the tables. Usually if the ampacity is correct the horsepower rating is also but the example given of 28a. might not be the case.
