Article 555 is for marinas & boatyards. Note 555.13(B)(3) 2005 NEC. I hope this helps.

The waters under a pier, floating or otherwise, are unlikely to be considered ?navigable.?
Much depends on the location of the ?electrical datum plane,? as defined in 555.2. If you are in Washington State, that definition has been deleted, and therefore has no relevance. I would invite your attention to 555.9 and to 555.(A)(1).

Dock Lighting NEC code
Dock Lighting NEC code
Thank you for your response. Home owner (residential) has dock over the
ocean and has installed a fluorescent light (metal) in a PVC enclosure. 120v
20 amp circuit. The light is fixed under the dock five feet above the water.
Does code allow for PVC pipe or seal tight connection to the fixture?

Art 555 Marinas and Boatyards
555.1 Scope
Private, noncommercial docking facilities constructed or occupied for the use of the owner or residents of the associated single-family dwelling are not covered by this article.
With that said, I would like to see a listing of the fixture, call the fixture company and/or use the Art 555 as guidance as to the location of the fixture - Datum Plane - and make my decision. Does the tide come up any higher than the 5 feet mentioned?

If Code 555 does not apply to residential, then what NEC code applies to dock lighting (under dock). We are under FEMA regulation in the Florida Keys.
If there is no specific code for under dock lighting (fixed) should we use the
over swimming pool code (not less than 12' above the water).
The tides vary and there could be less than 5' of clearance to the water, especially in hurricane season. What is the residential code? If there is no specific code where would the liability be if there was an injury from this installation?

Tori-
I wouldn't specify an explosion proof box for over the water because of the corrosion. Aluminum enclosures and SS bolts can create galvanic corrision if they are exposed to salt air. The corrosion would then compromise the flange area sealing properties.
NEMA 4X fiberglass is the ticket.
Donbos-
Look at some Hydrel or Marina Power and Lighting fixtures for your dock. I've used several "Snook lights" on resi docks and made sure the splices were above the electrical datum plane. 3M 5200 makes a great sealant for the SOW cord connections to remain water tight.
