What is difference between XHHW and XHHW-2?
THHN/THWN-2 is a thermoplastic product, while XHHW-2 features thermoset insulation….HOW TO KNOW THE DIFFERENCE.
| THHN/THWN-2: | XHHW-2: |
|---|---|
| T = Thermoplastic | X = Cross-Linked Polyethylene (XLPE) |
| HH = High Heat Resistant | HH = High Heat Resistant |
| W = Water Resistant | W = Water Resistant |
| N = Nylon Jacket | (Not Required) |
What is Type XHHW-2?
XHHW Wire Overview This type of insulation is used for both copper and aluminum conductors which are either solid or stranded, depending on size. XHHW-2 insulation, which is similar to XHHW, is suitable for use in dry or wet locations up to 90° C (194° F).
What is XHHW wire rated for?
XHHW-2 is rated up to 90° C in both wet and dry environments. THHN is rated up to 90° C in dry environments only. Dual-rated THHN/THWN carries a 75° C wet-environment rating. The 0.004” nylon jacket on the THHN is hydroscopic (that is, it absorbs moisture), which prohibits its use in wet locations at any temperature.
Where can XHHW wire be used?
XHHW wire is generally used in residential, commercial and industrial buildings and installations for the purpose of power distribution. The cable is manufactured in both copper and aluminum conductors and typically ran in conduit or other approved raceways for services, feeder and circuit wiring.
Is XHHW-2 rated for underground?
Registered. You can’t run type SE cable underground. You don’t have any problem running individual XHHW conductors in PVC underground.
Is XHHW-2 wire sunlight resistant?
SPECIFICATIONS: Sunlight Resistant (all sizes and colors). VW-1 available in all sizes. Type XHHW-2 conductors are primarily used in conduit or other recognized raceways for services, feeders, and branch circuit wiring, as specified in the National Electric Code (NEC). XHHW-2 conductors are rated for 600 volts.
Is XHHW wire UV resistant?
Sunlight Resistant in all colors. Use of lubrication is not mandatory to install QI® XHHW/ XHHW-2 conductors in the raceways. Complete cable is Lead Free and RoHS compliant.
Can XHHW be used in conduit underground?
Can Seu cable be buried?
SE cables simply can’t be buried, conduit or no conduit.
What’s the difference between THHN and XHHW wire?
THHN wire comes with a dual rating: THHN / THWN, which means it’s appropriate for both dry and wet applications. XHHW and XHHW-2 XHHW-2 wire is the next generation XHHW wire. While its main use is for residential, commercial and industrial buildings, it is also used in raceways, feeder and circuit wiring.
What’s the temp of a XHHW 2 wire?
XHHW-2 is approved for use up to 600V and is UL Listed for 90° C (194° F), in both dry and wet locations. The previous generation of XHHW had a lower temperature rating, approved up to 75° C in wet environments, making the next generation XHHW-2 wire a more useful and an ‘all environment’-type product.
What’s the difference between XHHW and xhh-2 insulation?
According to Underwriters Laboratories (UL) Standard 44, XHHW insulation is suitable for use in dry locations up to 90° C (194° F), or wet locations up to 75° C (167° F). XHHW-2 insulation, which is similar to XHHW, is suitable for use in dry or wet locations up to 90° C (194° F). • CSA c22.2. No38
Which is the next generation of XHHW wire?
XHHW-2 wire is the next generation XHHW wire. While its main use is for residential, commercial and industrial buildings, it is also used in raceways, feeder and circuit wiring.
