555.1 scope does not cover docks and boatlifts in single family so the question remains.

Perhaps if the original question had stated it was for a single family you might have received a different answer. Left my mind reading equipment at the office.


So the question shall continue to remain.....................

art 682 new for 2005

art 682 new for 2005

This post has kinda died but I think it needs a little attention. It is new to the 2005. The 2005 handbook is the best place to read about it. It does 100% apply to man made lakes with fountians and airiator pumps. I do have quite a few questions as you all will when you read it. Does it apply to residential docks and boat lifts?. I think it does as it talks about floating structures and land areas subject to tidal fluctuations. Also structures intended for rise and fall of water level without laterial movement.
682.11 Location of service equipment shall be 5' from the shoreline. Not on the dock. The last sentance is the one I am most curious about. "Service equuipment shall disconect when the water level reaches the hight of the established electrical datum plane." Does this mean float switches and shunt trip breakers???

This makes no sense. If your equipment is located above the plane why would you want to shut it down at, for example, high tide?

I see what you mean Cavie, do you have an install your working on that would fall under 682?

You wouldn't need to shut down at high tide. The datum plane is 2' above high tide and your equipment must be located no less than 12" above that. So your equipment must be 3' or highter than high tide. It "must disconect" when the water reaches the 2' over high tide line. Did I mention the disconnect on the post 5' from the seawall in the middle of the yard?

I am the lucky guy who gets to figure out how to inspect it after you figure out how to install it. Inspect about 4 docks a month. That is how I stumbled into this.

I have a meeting with a very sharp AHJ today. His area includes part of the Intracoastal Waterway. We have adopted the 05 here.

I'll have the book open to 682 and ask how he is enforcing this.

My sympathy to you,.... this is a good article on the subject, I have no personal expierance to draw on ,..sorry.

M.D. that was a good read, thank you. But I see the author skipped right over Cavie's 682.11 question.

The AHJ I know would have some input on this was out today. The inspector that came was suprised. We read it and talked. It is obvious that 682 is rearly if ever discussed at the Broward County Bldg, Dept.

So my question now is:
Is anyone out there aware of a buildging dept. that uses this as part of thier aquatic enforcement?

Thats my last bump. If there are no further posts may this thread die in peace.(untill 08)

Yeah it seems a little funky 555.1 says

"This article covers wiring, services, feeders,and grounding for floating buildings."

555.2 tells us to go to definitions and a dock seems to be a building

So article 555 is all about the building ? and 682 is all about the wiring being near or in a body of water not already covered ,Hmmm 555 does not cover water,,
it covers buildings that float,... so it looks like they both apply

682.13
Wiring methods and installations of Chapter 3 and Articles 553,555, and 590 shall be permitted wher identified for use in wet locations. Could that be any more redundant?

Mabey we should lobby for the elimination of 682 and get 3 pages of coupons instead. Or how about 3 more pages of Art. 250?:grin:
 
Whoops ,..I missed what it was you were commenting on ,.. sorry. They did say this in the Article , which Cavie already touched on .

From a design standpoint, the automatic disconnecting requirement will likely necessitate some sort of arrangement involving a float switch or other high water detector driving a shunt trip on the main service disconnecting means. While in theory such a system is simple and well-known, this arrangement in a waterway environment subject to silting, flooding, drifting debris impingement, etc., poses a number of design and operational challenges associated with proper location of the detector and keeping the detector clear of debris and mud to ensure proper operation. Preventing detector clogging and jamming is an issue that has been existent in high water and flood detection systems for a number of years. Choice of a detector location that is sheltered from flood-driven debris, and use of a reasonably silt-resistant detector will help reduce problems, but routine maintenance and inspection are required. Local flood control agencies can usually provide area-specific data on viable local design and maintenance/inspection strategies and equipment selection for reliability.
