Would you use this in a raceway that is located in a wet location?



I am going to say no.

I would in a heartbeat.
What about 310.8(C)?
(C) Wet Locations. Insulated conductors and cables used
in wet locations shall comply with one of the following:
(1) Be moisture-impervious metal-sheathed
(2) Be types MTW, RHW, RHW-2, TW, THW, THW-2,
THHW, THWN, THWN-2, XHHW, XHHW-2, ZW
(3) Be of a type listed for use in wet locations
1 and 3
Whatever.
Actually now that I think about it I would strip it. I have a vacation coming up.

You only need to comply with just one.
Notice in the picture is has "Oil resistant" on the insulation.
Although THW is accepted, would not the insulation also show "moisture resistant"?

Crap,, I missed that.:jester:
I got a service later this week and was wanting to use this up. Found a lot of it in the material trailer.

We normally used copper for everything. I am using AL now for services.

Thanks. My DA miss read.
The W in THW means it is listed for wet locations. Do you even electric, bro?
I don't get it. It's THW, why not?
I have been so used to just getting THHN-2 copper.

I saw this in the trailer and was not sure.

I know now.:thumbsup:

I do, I don't know everything though.

Somewhere I thought that the conductors needed to be sun light resistance also for service risers.

You'll also notice that the THHN you use is cross-listed as THWN, as the W again notates listed for wet locations. If it was just THHN, it would be a code violation to install it in a wet location.

I saw once a table that listed what the lettering meant. I thought it was in the NEC is where I saw it. I tried to find it again briefly and gave up.

The only one I can remember it MTW.

Even within a raceway?
...YES....now buy us beer....
It shows you are a J-man. You have to admit you ask some pretty basic questions sometimes. Did you lie on your personal info?
