Would like to add that those instructions also include limitations enumerated within the listing standard. E.g. the part of UL 514(B) that says, to paraphase, that a fitting with non-standard male threads shall be supplied with a locknut and shall only be used to connect to a sheet metal enclosure.
I'm still going to make the case that isn't clearly what is meant by the code when it says "instructions included in the listing". The listing is not the standard. If the manufacturers are failing to provide instructions they should be providing then that's between them and the NRTL, and doesn't create a code violation by the installer.
Years ago I worked at two places that had nightly high pressure wash downs and always used quality Thomas & Betts rain tight fitting on EMT conduit with no major water intrusion problems. We tried to avoid entering top of NEMA 4 boxes and start stop stations. I never trust any die cast flimsy fittings. Appears somebody dropped the ball when they transitioned to so called rain tight gathered fittings. Retired but still have a collection of T&B 1/2 to 1"" EMT rain tight fittings that I will use when I get an EV vehicle.
