For Florida, what is the requirement for electric for a boat dock for residential. I looked in 2014 NEC and 555 does not apply to residential.
Specifically i am asking about GFCI protection for feeder and what type of panel would i need, like NEMA 3r or 6P?

Thanks for your responses.
 
thank you. i just read the 2017.
i do have an issue. it says gfi protection required on mains, feeders and branch. if you put gfi on feeder and you put another in sub panel they trip. you cannot put 2 in line i believe this is a typo.

Yes, GFCI and/or GFP/GFCI devices can be in series. But also note, terms are important here. The 2017 requires 30 ma GFP on the supply to a marina, not GFCI.
Also, does this even apply in Florida for a residential dock? I thought Florida was on the 2014 NEC.

If 2014 applies they can't make you do it, but would not be a violation to install that 30mA GFP on the feeder either.
 
if inspector wants it he gets it. not worth arguing this. i would put gfp on feeder to dock. I do not see anything about what type of panel should be used. NEMA rating i am referring to

What conditions is the panel likely subject to? If it is indoors and not likely to get wet NEMA 1 enclosure is fine, outdoors will likely need at least 3R, but if water will spray/splash from below may need to be more then 3R.

Salt water - may need to add an X to the designation.

outside on dock. so i think 6 maybe even 6P i have to find out if dock gets submerged at all

thanks

If the panel will be outside, obviously a NEMA 3R would be the minimum. If it's inside, NEMA 1 is fine. If it's near salt water, I would suggest a stainless steel panel, or put a regular panel WITHIN a fiberglass NEMA 4X Hoffman box.

In my state (Washington), the code requires "corrosion resistant" enclosures for marina work. Salt air eats up panels REALLY fast.

Regarding the GFI protection: I would put a 30 mA GFI breaker in the dock panel that feeds the dock power. They aren't cheap, but it is required. You can also put a standard 5 mA GFI breaker, which is much cheaper, but you run the risk of nuisance tripping.
 
Code says that if all branch circuits are protected, main line doesn't require GFI

Code says that if all branch circuits are protected, main line doesn't require GFI

2014 Code says that if all branch circuits from shore subpanel are protected, main line doesn't require GFI, 2017
