Liquidtight Flexible Nonmetallic Conduit...

Do you mean can you have a portion submerged or do you mean the whole system including fittings?
I would think that as long as the fittings were not submerged, you should be fine. The NEC doesn't seem to even address this, but I feel that common sense would keep you from submerging the fittings.
Good question. I doubt that the manufacturer would stand behind it if it failed under this use, though.
 
It has to be fastened every 3 feet...it's rated for a wet location....do you know of a listed fastener for underwater? :grin:

I'm only going to have a 2' piece in a commercial water fountain before it hits the brass j-box provided by fountain contractor. And the fittings would be submerged. I have never totally submerged wiring before so this is why I ask.

I think 556.42 would prohibit the fittings to be immersed in water, since they're only listed for direct burial or encasement in concrete. (I also meant to type in 3 feet for the maximum distance between fastening.):)

556.42 which code book are you using, I dont have that in the 2005.

Is there any reason it can't be submerged in water? Would 356.10(2) allow this?

I'm thinking 680.51(E) would apply here.
It mentions "cords" not raceways.

What about 680.52(2)(B)? It say where box is fed from nonmettalic conduit. The lights will have cord into my j-box. I want to feed the j-box with 2' of liquidtight. No good?

Also 680.51(E) says equipment shall be equipped with provisions for threaded conduit entries OR be provided with a suitable flexible cord.
 
680.52(B)(2) does allow nonmetallic conduit.

EDIT:
I don't have an answer chevy.

The last fountain I actually looked at, sits in front of City Hall...the lights have cords on them.

I'm not saying it's "right/wrong"; "better/worse"...etc.
I just don't know.

Right and the lights I have will have cord also. But the lights go to a junction box where they're all tied together. My question was is it ok to use liquid tight to feed the j-box? I'm thinking yes, I guess I'll find out when inspector come. :)

You're gonna make me take a trip to City Hall and post a picture of their fountain lights....I understand now ;)
 
So what section in the code covers the small water features that people install in their yards. They usually have a pump to move the water uphill and it waterfalls down to the pump again.

It's not a fountain.

I'd be inclined to say that it would fall under 682. These water features fit the definition in 682.2:

Bodies of water that have been constructed or modified to fit some decorative or commercial purpose such as, but not limited to, aeration ponds, fish farm ponds, storm retention basins, treatment ponds, irrigation (channel) facitlities.

As far as the LFNC goes, I don't find anything in the U.L. listing that says they can be submerged, but then again there's nothing that says they can't be either. The J-box has to be filled with potting compound, so water entering it from the LFNC isn't an issue. I'd guess that the only real concern would be water entering the conduit and migrating out of the fountain into your raceway or junction box that the LFNC is connected to outside of the fountain. I'd have to think that a properly installed fitting would prevent this, but I honestly can't say for sure. I've never seen anything but flexible cord used in a fountain, but then again I haven't looked at all that many and it's been a long time.
