High voltage supplied to a floating dock

Just FYI I think you mean low voltage

I still see nothing that modifies the terminal location in 555.9. 555.13 requires the junction boxes, 555.9 tells you where the junction boxes are permitted to be located.

I understand but it seems to be in conflict in the requirements of 555.13(B)(4)(a)(2) cord to be placed underside of pier.

Sorry for being so imprecise. Use of term high voltage was relative to that of a simple lighting circuit in typical residential applications, or other dock power more prevalent for dock lights or a radio. From primarily residential work perspective, in this relationship low voltage would be under 50V or more likely 12-15V as in LV lighting.

The wiring method is totally independent from the location of the required terminal boxes. Both of those code sections must be applied to your installation.

Customer has purchased an electric boat that requires an EV charger 50Amps. Charger cord limited from mfg specs to 13ft and dock mounted charger pedestal. Dock is a floating dock that needs to be at least 40ft from shore for boat to approach.

Different approach. If the dock is the same length each year, could you use underwater cable to a fixed piling for the charger?
