Dock power

[marcerrin]

Hello all! Just have a quick question to run by you all. I'm bidding a job running power to a dock. I've looked through the code book and searched a few other avenues and haven't been able to find much info on it. I'm wondering if the feeder going to the dock (50 amp) needs to be GFI protected.
My biggest problem is if it does need to be, the feeder is @ 200 ft long and I'm afraid of the distance tripping the GFI breaker. The feeder will run from the house, down the yard to the dock and @ 20' under the dock (not in water, just piped on the underside) before it reaches its OCPD. I think I'm OK without GFI protection, but wanted to run it by some others first.

this is just seat of the pants, but if you protect the feeder with a
50a. breaker at the panel, and then have a gfci in the dock pedestal,
does this solve the problem?
(as i haven't even looked in the code book, i now firmly place my
head on the block, and await the ax.)

Have you taken a look at Article 555?

I believe you will find all of the answers you are looking for located in that article.

Article 555.1 Scope....." Private non commercial 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."

My original post wasn't completely clear as to whether this is for a SF dwelling or not, it is.

ive done some dock power work. if the feeder is for shore power then the shore power receptacles dont need to be gfci but if theres 120 volt receptacles on the pedistal then they need to be gfci. the shore power receptacles are just for the boats to plug into

I do alot of dock power.I typically just install a dock power pedestal and run the
50 amp line to it.Works like a charm.Its got a ship to shore outlet,and a 20 amp 110 gfi,along with a nice little light on a photocell.They make ones with or without the water hook up.I drop in the pex while I have the trench open and sub out my plumber to hook up the water.People always gotta have water to clean the boat and the fish. And its 100% code compliant

If it is a Corp of Engineers lake, you will need to obtain their specifications, they have their own rules and regulations for shore and dock power.

I have to admit I was thinking of a loading dock and not a boat dock since it was not specified and I was wondering why the post was not making sense.

Took me about 2 minutes to figure that out. Just an admission of well you know
