No, the largest of the 2 is required.
Look at example D3 in Annex D.
*In the example, 125% of the actual connected lighting load (8500 VA
? 1.25 = 10,625 VA) is less than 125% of the load from Table 220.12, so
the minimum lighting load from Table 220.12 is used in the calculation.
Had the actual lighting load been greater than the value calculated from
Table 220.12, 125% of the actual connected lighting load would have been
used.
