Residential dock. 50 amp feeder to a "lighthouse" pedastal on the dock. Pedastal has 50 amp breaker that feeds an integral TL receptacle, and a 20 amp breaker that feeds an integral 120v GFCI recep. Question is; do you need a disconnect at the shore.
I have a lock-out on the OCPD in the house. The pedastal sits on the dock, about 20' from shore.
I've looked in the NEC and can't find a code reference.

*remember, this is a dock for use at a private residence.

Marcerin,
I'm sure you are being careful. Or you woudn't be asking questions. I just thought this article might be an intersesting read. Since it is about an electrocution at a dock. It was due to stray current in the water.

http://www.mikeholt.com/newsletters.php?action=display&letterID69

It says the letter no longer exist. I'll try to find it.
It's titled ." The electric shock drowning of Samantha Chipley"
It's in the newsletter section of this site.

I think 555 is the article that you should be looking at and there is no requirement , that I see ,..for a disconnect other than the one called for in article 555.17

Whoops just read the scope for 555.. " single family dwelling are not covered by this article......
