With the new Art. 409 (Ind. Control Panels) in the 2005 NEC, I understand that the panel with two or more devices should be UL listed, or equivalent. The question that I have been trying to understand is under 409.110 - Marking. The statement "shall be marked with the following information that is plainly visible after installation" is under question here. What is your interpretation regarding "plainly visible".
Does this mean that all of the information in items 1 through 6 under 409.110 have to be on the outside of the enclosure/panel or can it be visible on the inside cover of the enclosure/panel?
