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.
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 the maximum temperature rating of type XHHW insulation when used in a wet location?
The maximum temperature rating of a XHHW type insulation is 75 degrees Celsius or 167-degree Fahrenheit, when used in wet locations.
Is XHHW-2 rated for direct burial?
1 Type XHHW/XHHW-2 cable shall not be used in direct burial applications. 3.4. 1 The ampacity of Type XHHW/XHHW-2 cable shall be determined in accordance with Table 310.16 of the National Electrical Code®. The installation should not exceed the temperature ratings of the terminations and equipment.
Is XHHW-2 rated for 1000v?
Type XHHW-2 is permitted to be used in wet or dry locations at temperatures not to exceed 90°C. Type XHHW-2 is permitted for 600-volt and 1000-volt applications. Suitable for applications requiring low-leaking circuits and a dielectric constant of 3.5 or less.
Why would you use type XHHW-2 over Type XHH 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 does XHHW-2 mean?
High Heat-Resistant Water-Resistant
XHHW-2, or XLPE High Heat-Resistant Water-Resistant, Wire is a general-purpose wire suitable for use in conduit, raceways, feeders, and branch circuits. It is also often found in power distribution systems in industrial, commercial, and residential buildings. It features XLPE (Cross-linked Polyethylene) insulation.
What is XHHW used for?
XHHW Wire Overview XHHW is an alphabetism or initialism which stands for “XLPE (cross-linked polyethylene) High Heat-resistant Water-resistant.” XHHW is a designation for a specific insulation material, temperature rating, and condition of use (suitable for wet locations) for electrical wire and cable.
