I have a question about this no lube thhn, all the ads and the promo video I've seen show this wire being pulled in underground conduits. Now it seems that it is only listed as thhn and not the standard thhn,thwn,mtw. So wouldn't be against code to install a listed wire for dry and damp locations in a wet location?

Yes if thats true
 
Here is a thread where Southwire's SimPull was discussed:

New Sim-pull condcutors



The "Cliff Notes" are that SImPull is dual rated as THHN and THWN...

APPLICATIONS
Southwire SIMpull? THHN or THWN-2* conductors are primarily used in conduit and cable trays for services, feeders, and
branch circuits in commercial or industrial applications as specified in the National Electrical Code 2 . When used as Type
THHN, or T90 Nylon conductor is suitable for use in dry locations at temperatures not to exceed 90 ?C. When used as Type
THWN-2* or TWN75, conductor is suitable for use in wet or dry locations at temperatures not to exceed 90 ?C or not to
exceed 75 ?C when exposed to oil or coolant

A rep(?) from Southwire posted ( #36 )this:
DaveMercier said:
Southwire, after reviewing the numerous posts in this forum, has decided to change the large print on SIMpull THHN to make it clear that it is rated for both wet and dry locations. Going forward, the large print on SIMpull THHN will also include THWN-2.

A little background about the "large" print on the conductor ?
The large print was added to help installers and inspectors to quickly identify the cable size. This was in response to complaints that the required NEC/UL print is typically too small to be easily read. The required NEC/UL print legend will continue to be printed on the opposite side of the "large" print on the cable.

The thread was a good read...give it an eyeballing
 
As far as I know, it is not dual rated at this time which means it is only for dry locations.

We used this stuff last week and it does contain small lettering on the opposite side stating that it is THHN/THWN rated.

I actually started that thread a month or so ago when the stuff first showed up on the job. I wondered about the big lettering that only mentioned THHN. I'm glad to hear that Southwire has agreed to include THWN in big lettering also. This will end any confusion come inspection time.
 
I just finished running power for a new color copier being installed tomorrow morning and I discovered that the 2C12 NM that I was installing was SIMpull. My wholesaler was out of 2C12 so I grabbed the cheapest box at Rona. It worked out to $0.85/ft - I could have bought it off the rack for $1.25/ft. For 'normal' 2C12 NMD90 my wholesale cost is $0.36/ft.
I was kinda scratching my head on the purpose of 'lubed' NM, and didn't notice any difference pulling through joists. I'm wondering how much of the cost overhead is retail markup, and how much is due to the Silicone IMpregnated nylon. I do like the purdy yellow color though.
