coming into top of 3R wireway outside

[firebird1988]

So, Working on a client project. I have a wire trough outside. A Double Throw Safety Switch will be installed above with a outdoor rated breaker panel. Part number DT223URH-NP on the double throw safety switch.
The wire through will have zero splices or lived components. my understanding is that I need rain tight fittings and was going use Myers hub.
Sigma ProConnex™ 2" Rigid Insulated Raintight Hub
Model Number: 02-54075.

Now am I wasting clients' money trying to make it waterproof even tho there is zero splices or lived components inside this wire trough? Now on the backside of the wire trough will entry into the house which will have live components with same level of the wire trough but that pipe will be sealed with duck putty.

Make it as raintight as you can. The bottom of those collect dirt which turns to mud then rust.

And there can be issues with water from condensation inside. Seal all conduit runs into though,
What type of wireway/trough are you using?

IMO your plan of using Myers hubs is fine. You could also use sealing locknuts with rigid nipples.

any service conductors involved ??

Treat the outside like no rain will get in, and the inside like it will.

Interestingly, there doesn't seem to be a specific code requirement to use a "weatherproof" conduit entry on the top of a 3R wireway. 376.10(3) says permitted In wet locations where wireways are listed for the
purpose. Do the instructions dictate entry methods? I have never thought to look.

Yes exactly.

Treat the outside like no rain will get in, and the inside like it will.

Using a wire way which is a raceway. 376.22
225. 22 applies. raceways arranged to drain. Usually there is a couple holes in the bottom corner or the 3r metal wire way.
In Artical 100:
Location wet
Raintight.
Very well said Larry.
If you don't mind I'm going to use that one at work. You will get the credit.

 

[LarryFine]

Yes exactly.

Very well said Larry.

I love it when you guys get me.

If you don't mind I'm going to use that one at work. You will get the credit.

By all means, please do.

Well, it's raining in Tulsa today.
Wonder today's topic will be.

I'm going to end with your statement Larry.
Thank you

Ok, I'm slower than most.

Can you expand on this?

Treat the outside of the gutter like no rain will get in, and the inside of it like it will?

In other words, do what you can and should to prevent rain entry, but do what is necessary to allow the inevitable leakage to escape, all the while keeping energized components above any non-sealed holes.

So actually, "Treat the outside like rain will get in and treat the inside like it will also".

I think he means "Take steps on the outside to keep rain out, but take steps on the inside to handle rain getting in."

Yep, it just a fun play on words.

If you have rain getting in you didn't do a very good job of taking steps to keep the rain out.

Maybe, "Take steps on the outside to keep the water out, but take steps on the inside to handle any water that may have gotten in."

A difference between compression and rain tight compression could be one example.

Out side install:
2" EMT into a hub or using a sealing locknut on top of the 3R metal wire way using compression versus rain tight compression.

2" EMT entering the bottom of the wire way.

I know we all do it but not sure the threads on an EMT connector is made to be screwed into a hub.

Tulsa, I dont quite follow. Regular compression EMT connector would not compliant outside no matter how you dress it up with a hub or sealing locknut (both of which are technically not compliant to use on a EMT connector). Why not just use a RT EMT connector right into the top by itself?
