If I'm reading note two correctly it appears to only apply if the primary overcurrent protection is sized larger than 125% of the pri FLA?? In that are compelled to additionally protect the secondary winding.
If the pri OCPD is sized to protect the transformers pri. per 450.3 (B) [pri protection only} , then OCP for the secondary winding is not required.
You may have multiple taps from the secondary of the transformer (as mentioned 240.21 (C) ) to several loads the secondary conductors must be protected per that section and article 240.
If your pri overcurrent protection exceeds 225 A (480/.83)I think Note two is applicable.??
RYAN could you indicate the paragraph in the 05 that references 240.4 I'm looking at the pre-print and appear to be missing it!!
