The raintight fitting debate has been done to death, and we all agree that the rubber washer is useless.
That said, what do folks do when entering the top of an enclosure through a hub, for instance?
I had to enter a enclosure through the top with a 2" EMT conduit, and the enclosure came with a 2.5" KO and Myers hub (shop screwed up on the punch size). I had to use a threaded reducing bushing to adapt the Myers hub down to the needed 2" EMT fitting. I ended up using read Loctite 603 retaining compound (thicker and more gap filling than threadlocker) and making up the whole assembly wrench tight before the Loctite set. It worked well, and seems to keep the rain out of the threads.
I was told as an apprentice that Loctite is an insulator, but my meter begs to differ. No measurable resistance across the threads after assembly. That makes sense, as the Loctite should fill the gaps in the threads and not interfere with the metal-to-metal contact at the thread faces.
I know exterior conduits are considered wet locations, but it still seemed prudent to keep water entry out of the top of the enclosure.
Thoughts?
