I found this at a pizza parlor. The ½” EMT is outdoors, totally exposed to the elements. Notice the set-screw connector; it is a potential for water to enter the pipe.

Here's a copy of an update I just got from UL regarding EMT "raintight":

Quote
Steel City® / Thomas & Betts, Inc. now has their EMT compression connectors, catalog numbers TC-111A-RT and TC-711A-RT in the 1/2 inch trade size, TC-112A-RT and TC-712A-RT in the 3/4 inch trade size, and TC-113A-RT and TC-713A-RT in the 1 inch trade size, Listed for "wet locations" or "rain tight" applications. The installation instructions for all three trade size connectors state, "Tighten gland nut until thread bottoms out." These connectors employ a knockout gasket to exclude water.

They also have their EMT couplings, catalog numbers TK-111A-RT in the 1/2 in. trade size, TK-112A-RT in the 3/4 trade size, and TK-113A-RT in the 1 in. trade size, Listed by UL for this application. The installation instructions for the 3/4 trade size couplings specify torquing the compression nuts to 600 in-lbf and 770 in-lbf for the 1 inch trade size couplings. All fittings are provided with solid compression rings (not split) to exclude water. Steel City® / Thomas & Betts, Inc. joins O-Z/Gedney LLC and Bridgeport Fittings Inc. as the third company Listed by UL for "wet location" and "rain tight" applications.

The standard EMT compression fittings are not listed for wet locations...S

The irony, of course, being the use of set screw connectors and couplings - not even the "old, leaky, formerly rain-tight" compression connectors.

I do have to wonder why the standards changed so drastically. I could understand if they drew a vacuum inside the pie while it withstood hurricane force wind & water, but couldn't a simple gasket of some type (neoprene?) have done the same thing as a complete re-engineer?

Oh, wait..... re-engineer = new inventory to replace old = $ for manufacturers.

At least he knew how to BEND the pipe. That is a lost art nowdays.

Who wants to bet water will pool on that step around the EMT & it'll be full of holes in 5-10 years.... Hope theres at least a ground wire in there if that happens

Amen to that! [Linked Image] Not often you find someone with the skills to create an aesthetically pleasing EMT installation & then they don't even know what fittings to use! [Linked Image] unless this falls under the "Last job before the weekend" clause!

There may be a whole stacks of those bends in various states piled up somewhere. These is the ones that made it.

Maybe he thought this was a DAMP location because it is protected by the "OVERHANG"!
I get that one alot relating those in-use covers.

before we jump to conclusions there maybr direct buried cable in the conduit and it is just being used for mechanical protection.

UGH! [Linked Image]

That would be guaranteed to get all sorts of people in a tizz in the UK - especially on a commercial property.

I just _hate_ to see conduit run like that - even though the bend is nice...
