CAN A BOX HEADER HAVE TWO NB CODE STAMPED TAGS ON IT? IF SO, WOULD EACH TAG BE ALLOWED A SEPARATE NB NUMBER OR WOULD THE SAME NUMBER BE APPLIED TO EACH TAG? THANKS , RADD02

Typically, not. Unless the box header was re-assembled with components from two different box headers.

 

[GenB]

Or different fabricators, Different numbers.
