Dont know the article off hand but the trough is sticking out way to far. Looks to me like it was ok at one point. I bet it was extended when the meter to the left was added, which I might think is a better solution to getting the taps to fit than usung the old hammer and 2X4 trick!
The work space shall be clear and extend from the grade, floor, or platform to the height required by 110.26(E).
Here's the rule: Within the height requirements of this section, other equipment that is associated with the electrical installation and is located above or below the electrical equipment shall be permitted to extend not more than 150 mm (6 in.) beyond the front of the electrical equipment.
That looks like a gutter screwed onto the face of another gutter. They must have cut the back out of it as I have never seen a 'gutter extention.' I can't think of a section to quote of hand but I imagine it would be a listing violation if nothing else. I could be wrong.
