Isn't 110.26 about providing a safe working space? And it defines the height and width of the working space. Then the table defines the depth of the working space (not a portion of it). This one's clear, to me. 480v. is 277v to ground, and condition 3. 4 feet clear from the bottom to the top of the working space. By the way, we're all getting panic hardware on the exit doors of our 1200A+ rooms, right?
