I have a tough spot, need to bury a 4" liquidtight run, about 3' long. I have PVC underground, and need to stub up to an outside panel. The problem is that I have obstructions which make cutting back, or modifying the existing PVC impossible. The easy easy way for me is to just use a short peice of liquidtight and come right into the bottom of the panel, painless.

Is there an issue with code here?

My code book is an hour away and I need an answer for tommorow morning before they back fill on me- otherwise I would check. Thanks for answering my stupid question!
 
I just went out to the truck. Says direct burial right on it- duh

Any other issues I need to be aware of coming up out of the ground? Protection from physical damage is a non issue here.
 
LFMC ...yes, if listed:
350.10 Uses Permitted.
LFMC shall be permitted to be used in exposed or concealed locations as follows:
(3) For direct burial where listed and marked for the purpose

350.42 Couplings and Connectors.
Angle connectors shall not be used for concealed raceway installations.

350.60 Grounding and Bonding.
Where used to connect equipment where flexibility is required, an equipment grounding conductor shall be installed. ....

From the '05.

You are talking about LFMC, right?

Why would it be an issue?
230.43:
(15) Flexible metal conduit not over 1.8 m (6 ft) long or liquidtight flexible metal conduit not over 1.8 m (6 ft) long between raceways, or between raceway and service equipment, with equipment bonding jumper routed with the flexible metal conduit or the liquidtight flexible metal conduit according to the provisions of 250.102(A), (B), (C), and (E)

(16) Liquidtight flexible nonmetallic conduit

(via 230.32)

He's going 3' ...maybe 5'.

3 feet max. It is LFNC actually. Thanks for the info so far.

LFNC is completely different!


356.10 Uses Permitted.
LFNC shall be permitted to be used in exposed or concealed locations for the following purposes:
FPN: Extreme cold may cause some types of nonmetallic
conduits to become brittle and therefore more susceptible to
damage from physical contact.
​

(3) For outdoor locations where listed and marked as suitable for the purpose
(4) For direct burial where listed and marked for the purpose


356.42 Couplings and Connectors.
Only fittings listed for use with LFNC shall be used. Angle connectors shall not be used for concealed raceway installations. Straight LFNC fittings are permitted for direct burial or encasement in concrete

356.60 Grounding and Bonding.
Where used to connect equipment where flexibility is required, an equipment grounding conductor shall be installed. ....

Looking in 230.32 again to 230.43(16) Liquidtight flexible nonmetallic conduit.


(Ok, so it's not that much different ;) )

What is the issue with LFNC being used in this application?
 
Celtic- I honestly see no such problem with using it how I planned, but, I wanted to ask others before I did the installation, also I am code book-less at home here Thanks for the help.

If you are online, you have access to the NEC

I have had problems using this directly from the site. It won't let me past the "I Agree" screen. (Keeps going back to same screen.) If I click on a link to the page I can get through no problem. I bookmark the page to go straight to it, but it won't let me in. :confused:
 
Well shes in the ground. Worked out PERFECTLY. But holy hell, those 4" liquid tight fittings were $300 each for straights!!!!!!!!!!!!! Tell me thats not insane. I didnt even buy them, I called my shop and they had one there that I got for free. That at least got me out of the ground and I will deal with finding one of the panel end when I can find one cheaper (maybe I cant).
 
300 bucks is insane. I bought a 2008 codebook in mini-form at Barnes and noble for 35 bucks. it kind of sucks compared to the big ones, but good in a pinch, and it fits in me pocket.
 
Called around today, found one in stock for $65. Thats more like it. I think the other supply house was selling me one made of gold.
 
We got a box of LTMC that was marked right on the box "non UL listed".

What would that be any good for?


... Now that I have posted that, I expect I'll probably get some good answers:smile:
