Looking for THWN-2 Wire?

Does your job or home improvement project require THWN-2 wire?

If so, you’ve came to the right place!

Occasionally, customers purchasing THHN for the first time ask if  our wire is THHN/ THWN-2 dual rated?  The answer is, yes.

All of the THHN wire Wire & Cable To Go supplies comes THHN/THWN-2 dual rated.  Matter of fact, most THHN wire made in the USA these days is dual rated with THWN-2.

Curious what THWN means?

Thermoplastic Heat and Water-Resistant Nylon Coated

(-2) indicates its rated 90 degrees for both wet or dry locations.

If you see the THWN without a -2 at the ends it means its rated 75 degrees for both wet or dry locations
