I get what you are pointing out now. [Linked Image]

I looked in some older NECs and found that as recently as 1996 both tables had separate ratings for fuses and breakers.

The 1999 Table 450-3(b) changed to what we see now.

I guess there was a proposal to change the table but not the notes.

Looks like you could put in a proposal.

You are certainly a careful reader of the NEC. [Linked Image]
