Yeah even punched holes are typically too large for the o-ring to cover. I mean I of course understand having some slop and play for easier makeup, but the whole system just needs to be completely re-engineered if you really want reliable sealing.
No, that will not pass inspection. The only way I have every seen pass all inspections is to do it the that electrofelon descibed, with a myers hum and RT connector.
Sealing locknuts have the same listing at a conduit hub. The use of a raintight connector with a conduit hub is also not compliant as there are no raintight connectors, that I am aware of, that are marked on the box as being suitable for use with fittings having female threads. In addition the hub is only listed for use with RMC.
You must not do jobs where you have to wrap an existing building with exterior lighting or do roofs with a dozen or two HVAC units - or you do and you are fortunate that they have the budget for RGS.No, I never use EMT outside.
That's why it's all nonsense to think you can enforce something just because they say it's supposed to work.

Right if it's something where a few drips of water won't matter. For example the nipple between a CT cabinet and the meter socket. No I'm not going to use a Myers hub on the side of the CT can for the 1" nipple. A 3R tap box below a meter is another one. I'll probably just use a rigid nipple and a ceiling lock nut, I don't see the need for a Meyers hub. I'm always going to arrange the splices such that they can't be dripped on and water won't surface tension down the conductor to the splice. EMT rain right couplings are another. There are already code sections that deal with water in conduits such as raceways shall be allowed to drain and conductors rated for wet locations. So I am using the rain tight fittings to pass my inspection, and I'm not concerned about some water in the conduit. So I'm going to make a call on what to use based on the importance of keeping water out. Yes of course there are situations I would definitely use a Myers hub.
. Right. So assume water will get in, allow for drainage with weep holes and such and arrange splices to be clear of drips and such, and use what fittings you need to pass your inspection.So what actually are we saying here?
I say, no matter what you do it's hard to keep the water out.

I don't think I said that. I just said hubs were not listed for anything other than RGS.
I think I pretty much responded to this.
Correct, many times it does not matter.
