Re: NEC 409 vs UL 916 ? AHJ reading interpretations ?

Welcome to the forum.
Article 409 is new to the NEC in the 2005 cycle.
Since it is new, there will be some glitches, and your question may be just one of those glitches.
Because of the wording in the scope which says " intended for general use...
what does it really cover???
My advice is speak to the AHJ and ask him what he is going to look for.
The article does say Industrial Control Panels, so I am not too sure if this would include certain types of lighting control panels.
409.3 gives some direction, but maybe not enough.
