Is it kosher according to the NEC to use such PVC conduit fittings as
pull elbows and LB conduit bodies outdoors on a 220-volt circuit? The
ones I have are not marked as being suitable for wet locations. Are
there some that are so marked?

If I can't use such fittings, how do I make 90-degree bends and T-joints
and also route conduit through a (wood) fence from one side to the other?

Yes, PVC and it's associated fittings can be used in wet locations. Be sure
the conductors you use inside the PVC are rated for wet locations as well

Any borg or electrical supply house will carry PVC conduit
specifically designed for exterior use. It'll be UF rated, water
proof, etc. It's usually grey. Look in the electrical section of a
borg, not the plumbing section. T'hey'll also have all the fittings
and connectors you need, including connectors that will allow you to
make turns and to connect the PVC to metal boxes. You'll need to pick
up special glue for this type of PVC.

I have the ordinary grey "Carlon" brand PVC conduit and fittings I was
intending to use (and the primer and cement), but then I read a claim
that for use in "wet locations" (which surely includes anywhere outside
-- but also underground, I understand) the fittings must be so marked.
The diecast metal outlet boxes I bought *are* so marked, so that made me
think that the other fittings are *not* OK for outdoor use.

If they are exterior-rated, that would normally be expected to be noted
if there is any actual rating stamped on them. How are they marked? Is
there a part number to verify against?

They have the Carlon and UL logos. The covers of the pull elbows are
marked '3/4" PULL ELBOW' and 'E990-E'; they have a synthetic rubber
gasket the same size as the cover. The LB conduit bodies are marked on
the inside with "PVC", the volume and the conductor capacity; they have
a sealing ring around the edge of the cover; a sticker on the outside
has "E983E" and the UPC bar code.

I don't have the Carlon catalog memorized ( ) -- look 'em up if
you're uncertain. Sounds like they would most likely be exterior-rated
from the description.
