Is it legal to run flexible conduit outdoors?
My intent is to go from a breaker box on my deck into a tool shed I
built at one end of it to power one light. My intended route is along
the framework under the deck which is elevated about 2 feet off the
ground.

NEC 2008 says....
(FMC Flexible Metal Conduit)
348.12 Uses Not permitted. FMC shall not be used in the Following:
(1) Wet locations.
(2) in Hoistways, other than permitted in 620.21
(3) In storage battery rooms
(4) In any hazardous (classified) location except as permitted by other
articles in this code.
(5)Where exposed to materials having a deteriorating effect on the
installed conductors, such as oil or gasoline.
(6) Underground or embedded on poured concrete or aggregate.
(7) where subject to physical damage.
So no, not legal if used outdoors. Use PVC schedule 80 instead.
Cheers

With some kind of "plastic" insulation overlay it's used all over
Arizona for connecting a local breaker box to objects with some
vibration, such as air conditioning units and pool pumps.
For RH's use though, I would use PVC... but paint it with a good latex
paint, otherwise the UV will deteriorate it.

Yes, there is a special outdoor flex cable, metal covered by grey
plastic. I used it to go from my junction box on the outside of my
house to the sauna's sub-panel for my sauna and pool and other outdoor
electrical. If you want to use rigid for some runs (any you do, if
you are going any distance. That stuff is expensive!) then use
schedule 80, the grey stuff, not the white stuff. It is UV resistant.
When in doubt, follow the NEC! ;-)

That’s called LFMC (Liquidtight Flexible metal conduit), which is
allowed outdoors. And more expensive than Schedule 80.
And called out for connecting pool pumps and such.

Rustoleum's "Painters Touch" paint has very good UV tolerance. Painted
the Screen frames on Moms house about 10 years ago, and they are still
holding up. Also Glidden Endurance is THE Paint for outdoors. Not
available in the big chain stores, only the little guys carry it.

This is called in most fields "Seal tite/tight" or "Liquid tight"
But the non jacketed types should not be out side or in corrosive areas.
PVC pipe for underground runs should be used.

Depends. Where are you? And, do you mean FMC or LFMC?
Here (US) LFMC is acceptable for use in wet, above-grade
locations (I think you also need compression fittings on
each end of the conduit).

LFMC should be OK, there (check your local codebook).
I would advise a coating of paint just to cut down
on the inevitable deterioration that continuous sun exposure
*will* cause (most unpainted LFMC around here is "toasted"
on one side :> ). Almost any latex paint will do...

Why flex? Its expensive. Particularly the stuff permitted outdoors. If
its exposed, you probably should use EMT (metal conduit) with couplings
approved for wet locations. If the distance is considerable, you might
be able to transition to PVC under the deck. Your local inspector might
consider the 2 foot access as suitably protecting the conduit from
damage (and UV). That might save you a few bucks (keep in mind that the
wet location pull boxes and fittings at the transitions will eat up your
savings pretty fast.

Some have assumed metallic conduit in their answers. Instead,
use liquidtight _nonmetallic_ flexible conduit, such as Carflex:

Wonderful stuff, easy to work with and code compliant for you.

Is it legal to run flexible conduit outdoors?
My intent is to go from a breaker box on my deck into a tool shed I
built at one end of it to power one light. My intended route is along
the framework under the deck which is elevated about 2 feet off the
ground.
NEC 2008 says....
(FMC Flexible Metal Conduit)
348.12 Uses Not permitted. FMC shall not be used in the Following:
(1) Wet locations.
(2) in Hoistways, other than permitted in 620.21
(3) In storage battery rooms
(4) In any hazardous (classified) location except as permitted by other
articles in this code.
(5)Where exposed to materials having a deteriorating effect on the
installed conductors, such as oil or gasoline.
(6) Underground or embedded on poured concrete or aggregate.
(7) where subject to physical damage.
So no, not legal if used outdoors. Use PVC schedule 80 instead.
Cheers
With some kind of "plastic" insulation overlay it's used all over
Arizona for connecting a local breaker box to objects with some
vibration, such as air conditioning units and pool pumps.
For RH's use though, I would use PVC... but paint it with a good latex
paint, otherwise the UV will deteriorate it.

Apart from the assumption the NEC applies to the OP, for the record I used
(in the UK) Kopex IP65 pliable plastic conduit to bring meter tails from an
outside box over the wall into my consumer unit. This met the IEE wiring
regs as the cable route required no explicit mechanical protection (by which
the IEE mean armoured cable, copper clad pyro cable or steel conduit).
However the Kopex tube is tough and does afford quite a lot of protection:

(Ignore the messy local wiring the last one - temp circuit now gone).

Some have assumed metallic conduit in their answers. Instead,
use liquidtight _nonmetallic_ flexible conduit, such as Carflex:

Wonderful stuff, easy to work with and code compliant for you.

Just out of interest, don't you have anything like this in the USA:
http://www.tlc-direct.co.uk/Products/SW2dot5slash2.html
It is what we would use and can be run anywhere - surface clipped, under
ground without piping, buried in the building structure.
The steel wire armouring is of course earthed hence the protection, both
electrical and mechanical.
