Can someone help clear up what I do with the LRC once I figure it out using Tables 430-151(A) and (B) and add it to the remaining loads to to obtain the an equivalent LRC for the combined load, as paragraph #3 has me do?

430-110(c)(2) says to size the disco means at 115% of the sum of all currents at the full load condition, which I do according to the second paragraph of 430-110(c)(1).
