What do you guys think about this... Bridgeport makes a line of conduit fittings that used to be U.L. listed as being watertight. Should an inspector have an issue with installing a compression type connector like this outdoors on a conduit riser that is entering the bottom of a panel where it is shielded from direct rain? This might be a trick question...
Why do I ask???
3" diecast Bridgeport EMT/IMC/Rigid connector = $15.
3" Rigid connector = $130 - $180.

Are you referring to a 'Myers hub' as your Rigid connector?

======

I've never seen diecast connectors ever given a RT listing. Steel, yes.

The newer RT connectors don't differ much: just an additional seal, AFAIK.

I've seen inspectors tolerate Greenfield/ flex ( not Sealtite ) for THWN-2 taps to HVAC condensers -- in residential situations.

In which case, might D.C. S.S. connectors also pass for your application?

BTW, at 3", DCSS fit both RMC/IMC and EMT.

The connector is a 3" D.C. compression connector that fits EMT/IMC/RGS and is the older style without plastic gaskets.
Since the fitting is under the panel it would be at most an
occasional damp location. I was wondering if would be code compliant to use the die-cast fitting since it is placed so as to prevent moisture from entering. 314.15 only addresses wet locations as far as the U.L. listing requirement is concerned. BTW, The rigid is being used to thwart copper thieves and is overkill for conductor protection in this case.

Sounds like the local AHJ determines if the underside of the panel requires a watertite connector or not.

Based on his decission, that would be your answer.

Asking him before you spend $$$.

Good advice. I tried calling a couple times but couldn't get through. Double locknut threaded rigid connections under a panel or box outside never seem to raise an eyebrow. The meter panels have weep holes in them anyways so it shouldn't be an issue.
