The solution to this problem calls out to use 210.19(A)(1) to get the total load and then to use 310.15(B) Informational Note No 2 -> Table 310.15(B)(16) -> 240.4(D)
Can I instead assume that using 210.20(A) to get the total load and then going straight to Table 240.6(A) to find that the next highest rated fuse or CB is 20A?
