If the price of steel goes up anymore, you may want to buy a nice chain and hang it around your neck instead. [Linked Image]

Check the manufacturers box label to see if it listed for a wet location. If it is not then you cannot use it outside.

nesparky's got the answer.

I don't think these have a raintight listing, just concrete tight.
I couldn't find any listed as raintight.

BTW, a good place to find this kind of info is: http://database.ul.com/cgi-bin/XYV/template/LISEXT/1FRAME/index.htm

The controversy is new; untill UL questioned its' classifications, they were.
Under the new criteria, only EMT fittings to 1" have so far been listed.
I'm not even sure if the controversy extended to anything but EMT fittings. Logic might say 'yes,' but the UL statements were pretty specific in singling out EMT fittings.

As to your question: Generally, yes. The exception is when used on the top surface of a box, panel, etc. In that situation, it is necessary to use a Myers' hub. If, as is the case with most service equipment, you are connecting to a raised hub, they're fine. (The concern is that pooled water will seep in at the point where the fitting meets the sheet metal. A Myers' hub has a gasketed face.)

John,
Did you find any listed as raintight?

West-Southern Inner-Northeast ...
I’m out of the loop these days, but in the 1980-1990 decades, in 2½-4-inch size, the only listed raintite fittings were made by “ETP Berger” and they were a compression-gland type connector/coupling with a very visible black-rubber boot as part of the gland nut. At that time, all other 2½-4-inch compression fittings were listed concrete-tite, but not raintite. ETP now seems to be part of OZ-Gedney, and I can’t find this type of fitting in their online catalog. Does anyone remember these? ETP even made raceway and elbows with integral 2½-4-inch booted-raintite couplings swaged on one end.

Note that 2½-4-inch EMT and rigid-metal conduit have the same outside diameters, but threadless fittings for either are not intended {or listed} to be interchangeable.
