I have a delima with an inspector. I ran a 8/3 w/grnd romex from a breaker panel to the outside of a house to a junction box. I went from that j-box with carflex accross under a wooden deck, benath a set of stairs, under a wooden walkway, up another set of stairs to a breaker box. I have a main in the house for the sub feeders in this conduit and a GFCI 2 pole breaker in the sub-panel at the hot tub. I have a 6 foot carflex pigtail to the hot tub. My inspector is telling me that I am only allowed a 6 foot piece of carflex to the hot tub whether it be on feeder side of the sub panel or load side of the sub-panel. He is quoting 680.42 A 1 as the rule for this determination. I am looking at 680.25 which says I can run the carflex, and then the ruling in 356.10 (5) which allows me to run what ever footage I need to as long as I strap in accordance with 356.30. Am I missing something here?

Yes, 680.25 is in section 2 , Permanently Installed Pools, 680.42 (a)1 ,in section 4 , Spas and Hot Tubs , modifies the requirements in 680.25.

Re: Liquid Tight Non Metallic Flexable Conduit
Aren't you required to have an insulated ground, and not just a covered ground for spa feeders? They pass romex to a spa in my area, but I don't think it's technically correct.

No. 68042(a)1 limits the length to 6 feet wether it is metallic or non-metallic liquid tight flexible conduit.

Re: Liquid Tight Non Metallic Flexable Conduit
The 8/3 w/Grnd Romex is just from the bottom of the panel and out into the back of the j-box. The conductors from the j-box to the sub-panel at the hot tub are thhn in all the proper colors;ie, black, red, white, green. is 680.42(a) talking about the length of carflex(LTNMFC) from the sub-panel to the hot tub? or what I am considering a feeder and feel should be address elsewhere in the code, the total length of said flex anywhere in the circuit?

In my opinion , 6 foot lengths for flexible liquid tight used in outdoor installations of spas & hot tubs

I would disagree with the use of THHN in conduit exposed to the weather.

Re: Liquid Tight Non Metallic Flexable Conduit
LFNC can be run as far as you want providing it is secured in accordance with 356.30.356.20 A allows 6 ft whips for utilization equiptment,I think that suffices as a hot tub.Why the NM though?A few more feet of thhn is cheap.
Please lets not get into THHN or THWN in LFMC
discussion again. :roll:

Most thhn is also stamped thwn so really the problem is we are installing thwn but calling it thhn.So no problem other than we forget what we are saying and doing.Never was a problem so nothing to fix,however romex is another issue and i can't understand even using it.Why ?
