Opinions please (marinas)

When reading 555.13(B)(4)(b) (requiring the junction box) you are immediately referenced to 555.13(A)(2)(2).

555.13(A)(2)(2)

Where flexibility is necessary as on piers composed of floating sections.

I've seen it posted many times that the code does not say what you want it to say, it says what it says.

So, I'm asking where is this junction box needed? I say it is only needed when you are wiring floating docks that are made up of individual sections.

The local AHJ says it is needed when you transition from a fixed pier to a floating dock. I say the code does not say that.

Opinions please/thanks,

I'm trying to determine the difference between your interpretation and the AHJ interpretation. It's not clear to me what you're in disagreement about.

If the AHJ says it is needed when you transition from a fixed pier to a floating dock, and you don't agree then I guess you're saying that you don't need any junction box at all or that you dispute where the box should be put.

"I say it is only needed when you are wiring floating docks that are made up of individual sections." So does this mean that you think you need one only if the dock is more than one section ?

I do see the difference in opinion between you and the AHJ. You are saying that a floating pier comprised of a single section does not need the junction box. The AHJ is saying that no matter how many floating sections comprise the floating pier, you still need a pair of junction boxes at the head of the pier, where the fixed landside section transitions to the floating section(s).

IMO, the code authors intended to require what the AHJ wants to require. But do the words, as written, say what the authors intended? It's a good question. My answer is yes, so I think the AHJ is right.

The key words in 555.(A)(2)(2) are "as on." When the NEC says, "Where flexibility is required as on piers composed of floating sections," the authors are giving an example of where flexibility is required. Another example of where flexibility is required is at the head of the pier.

I agree with Charlie

"as on" tells you that the words to follow will be an example
but the rule itself is found in the first part of the sentence, "Where flexibility is necessary"
