Is Thhn the same as XHHW?
THHN/THWN-2 is a thermoplastic product, while XHHW-2 features thermoset insulation. THERMOPLASTIC: Cheaper than Thermoset. Nylon Coating – Required for the Insulation System’s Rating.
Can Thhn wire be used in cable tray?
Cable types that are not presented in the table include single-conductor building wire types such as THHN/THWN, XHHW and RHH/RHW. Article 392 does allow these types to be installed as power conductors if they are larger than 1/0 and marked for use in tray.
Is XHHW-2 cable tray rated?
CME – XHHW/XHHW-2 CT, XLPE Insulated, Cable Tray Rated, 600 V, Aluminum Catalog Item.
What does XHHW-2 stand for?
Cross-Linked Polyethylene
XHHW-2. X = Cross-Linked Polyethylene (XLPE) HH = High Heat-Resistance. W = Water Resistance. Temp Rating: 90° C in dry locations and 75° C in wet locations.
Is XHHW more flexible than Thhn?
Flexibility. Even though its jacket is thicker and more protective, XHHW is also more flexible than THHN wire. The XLPE insulation of the XHHW allows the cable to bend and flex better than the THHN’s PVC insulation—so XHHW is much easier to work with during the installation process.
What is the difference between Thhn and THWN 2?
Both THHN and THWN wires are used in a variety of installations. Thermoplastic high-heat resistant nylon-coated wire, or THHN, is a common wire used for connecting branch circuits and appliances. Its counterpart is called THWN (or THWN-2).
Is XHHW rated for cable tray?
Suitable for installation in channels, ducts, wireways, cable trays, and raceways. Approved for direct burial in wet or dry locations and outdoors in cable trays where sunlight-resistant rating is required.
What is Thhn PVC tray cable?
Our Tray Cable (THHN-PVC) consists of a strong durable jacket rated for direct burial that is filled with multiple conductors of THHN wire. Being that it is rated for direct burial, you do not need a conduit. Many of our Tray Cables also come with a ground wire.
