I have been studying for the NH Masters, having difficulty grasping load calcs for dwellings, non-dwellings, etc. Using Snapz software as well.
1) Snapz says that you add in largest motor load at 125%, do you do that for the optional? I don't see that in the NEC Annex examples.
2) Is there such a thing as standard and optional calcs for non-dwellings?
3) For non-dwellings, is lighting taken at 125% or is that just for circuit sizing? Same for show lighting, is that taken at 125% for load calcs, or is that just for circuit sizing?
4) Why is this such a PITA?
Thanks in advance,
-Tom
