    I'm adding a new outdoor outlet, which I plan to run a new circuit from my main panel along the side of the house preferably with surface mount EMT.

    The connector transition from the in-wall wiring to the surface mount EMT is where I am having trouble figuring it out. I've seen a LB type connector used with SCH40/80 for electrical where they drill a hole in the wall and the LB transitions from in-wall to surface mount conduit. The issue I am having is I only see EMT LB connectors available with set screws, which aren't appropriate for outdoor/wet locations.

    Is there something else I could use other than a LB connector that would work with EMT and be suitable for a wet/outdoor location?

    I suppose I could use SCH40/80, but I have to go around a corner and I hate using those giant pre-formed giant sweeping 90deg connectors, that's why I was hoping to use EMT.

    Thanks in advance!

    The pros will chime in to add or change my answer if I am wrong, but I always use EMT compression connectors/couplers when using emt outdoors or moist/wet areas. use or remove the nut on it and screw it into the LB to go around your corner.

    You could use a single gang Bell box and a blank cover. That said if you are only finding LBs with set screw connectors you are either looking at the wrong thing or looking in the wrong place.

    Thanks for the responses guys, I was trying to think this all through in my head and I should have just went down to the hardware store before I posted.

    I went down to Home Depot and all their EMT LBs are set screw only, but the Rigid LBs are threaded and I can use them with a liquid tight compression connector. That will work perfectly!

    Thanks.

    A 3/8" NMB connector will thread into a 1/2" LB. If this will not get you far enough into the wall, then you could use a short 1/2" ridged nipple, with a 1/2" coupling, and thread the 3/8" NMB connector to it.
