Back fed Breaker

[tryinghard]

Does NEC address backfeeding - line in the load side - a breaker?

I also wonder if the industry accounts for these as "feed through" or rated to back feed?

Nope.... in fact it's a normal thing to do. That's why they make hold down kits.

You can also go to the manufacturer's sites for more info... as well as the UL White Book.

If the breaker is labeled as Line and Load then you can not reverse them.

If the breaker is labeled as Line and Load then you can not reverse them.

Are there any common one's so marked? I've often heard that as part of the standard question to this question, but I've never observed any in the field that were so marked.

Got it; 408.16(F). I also notice (D) "Where a panelboard is supplied through a transformer, the overcurrent protection in 408.16(A), (B), and (C) shall be located on the secondary side of the transformer."
This actually applies in my situation as the panel is being served from a pole mounted XFMR and is also mounted on the same pole just 15' below, I'll need to check inrush current also.
