Re: Using sealtite rather than conduit
Article 350 covers sealtite. I see no reason for not useing it if it's large enough.

Re: Using sealtite rather than conduit
680.25(A) Permits feeders on the supply side of panelboards supplying branch circuits to swimming pool equipment to be installed in liquidtight flexible non-metallic conduit. Liquidtight flexible metallic conduit is not an approved raceway for these feeders. Type NM cable (Romex) is also not approved for these feeders.

I didn't even think of 680.25 when I answered, thank you. The way I read your response, your two sentences seem to contradict each other.

Re: Using sealtite rather than conduit
Whenever the location you are in thought about is a 'special' location as far as the NEC is concerned, one should refer to those Articles first. Chapters 5, 6, 7 supplement or modify the requirements of chapters 1, 2, 3 and 4. Chapter 8 is not subject to chapters 1 -7 unless specifically refered to. See 90.3.
For instance, the only place I know of where you can install SOLID 8 awg in a raceway is in pools (Art 680). That is one of many, many modifications that are permitted.
If you are unsure as to what may be a 'special' location, look in the table of contents (chapters 5, 6, 7 and 8) that should help.
Curt's post does not contradict itself, the wiring methods are 2 different methods.

680.25 does not apply to hot tubs. 680.40 says that only Parts 1 and 4 of Article 680 applies to hot tubs. Also see 680.42(A)(1) and 680.42(C).

Re: Using sealtite rather than conduit
Don,
I disagree. 680.42 Says that a spa or hot tub installed outdoors shall comply with the provisions of Part I and II of this article, except as permitted in 680.42(A) and (B), that would otherwise apply to pools installed outdoors. The wiring methods permitted in 680.42(A)-(C) would only apply to the connection from the panel to the hot tub. The question was about a feeder to a new sub panel that a hot tub will be connected to. 680.25 is included with Part II and it states what wiring methods must be used for feeders.

Re: Using sealtite rather than conduit
From your post you say your running the wiring through your basement. You did not say if your hot tub was in the basement. Is your hot tub in the basement or out side.
If out side than parts 1 and 2 of article 680 apply if inside then parts 1 and 4 of 680 apply as Don already stated.

Re: Using sealtite rather than conduit
Curt,
You are correct that Part 2 does apply to outdoor hot tubs. I was reading too quickly this morning.
It appears that if the hot tub has a factory-installed or assembled control panel, then 680.42(A)(1) would permit up to 6' of LFMC in the run. Yes, I know that you can also read the section as saying only the hot tub manufacturer could use LFMC, but the code doesn't really apply to the construction and manufacturing of equipment, but rather to the installation of this equipment. In my opinion, you are permitted to use up to 6' of LFMC in the feeder to the hot tub.

Re: Using sealtite rather than conduit
Am I missing something here?????LFNC is conduit and as long as it is installed acordingly why can`t you exit a building in nm, change to LFNC
strap it witin 12 in. of box then strap it every 3 ft.........This would be a feed to the spa panel
and imho it would comply......

Re: Using sealtite rather than conduit
Don,
I agree that 6' of LFMC could be used in the field to connect a listed packaged spa or hot tub with a factory assembled and installed panelboard and were just supplying the feeders. From the original post we don't know if this is a factory supplied sub panel he is feeding or if this is a field installed and assembled sub panel. If the sub panel came with the hot tub I would say use the wiring methods in 680.42 but if this is a field installed and assembled sub panel that will have circuits installed to supply the hot tub and possibly other circuits I would say you need to use 680.25. Do you agree?

Re: Using sealtite rather than conduit
The original question is refering to feeding a subpanel. Section 680.25 specifically limits you to certain wiring methods. If this is an outdoor Spa, then you will follow Parts 1 & 2 of Art 680.
680.42(C) is the wiring method permitted for connection the the Spa equipment, not the subpanel.
Allen you post is correct for wiring to a Spa, but to the Subpanel it would not comply if it is an outdoor Spa.
