In terms of overcurrent/shortcircuit protection, are the conductors feeding off a panelboard's feed-thru lugs considered to be tap conductors and subject to Article 240.21? In particular, I have a 30hp 3ph, 208v, elevator application where I would like to utilize 240.21(F) and use the feed-thru lugs of a 400A main panel to feed the elevator controller breaker. Any and all guidance will be appreciated.
