Since 450.3 says "Overcurrent protection...comply with...(A), (B), or (C).", if I am providing overcurrent protection per (B), then I am not required to provide primary fuse protection for my indoor voltage transformer, correct?
If I choose to only follow (C), I can pick any size fuse I want because there is no reference to a table in (C), correct?
Or should 450.3 read "...(A) or (B) and (C)? What's the intent?
