[RE-wrenches] DC conductors in metallic raceway/conduit

[Christopher Warfel]

The reason behind this rule, going back through some history, was to 
reduce the possibility of a nail penetrating hidden conduit (conduit 
behind a wall). Since the conduit is exposed/visible, the chances of 
that action happening are small to none. So, the installer is saying 
that a literal interpretation is not consistent with the intent of the 
NEC. May have to ask the AHJ for their position.
