XHHW-2 Wire is commonly used in a variety of industrial applications, including use in conduits, raceways, feeders, and branch circuits. Another location where this type of building wire can be found is within the distribution systems of commercial, industrial, and residential buildings. This form of wiring is superior to similar wiring with PVC cabling because it will not emit toxic smoke when it burns, which is more common with other cabling using PVC. The coating of XHHW building wire is also much more durable than nylon coatings used in inferior wiring systems, enabling it to be more flexible during wire pulls. XHHW wire also is more durable in low temperatures and features better electrical properties.

While XHHW wire can be used up to 90 degrees Celsius (194 degrees Fahrenheit) in dry conditions, it can only be used up to 75 degrees Celsius (167 degrees Fahrenheit) in wet conditions. The XHHW 2 wire cable standard requires that the cable be XPLE insulated, water resistant, and usable in both wet and dry conditions up to 90 degrees Celsius (194 degrees Fahrenheit). These are available to meet multiple voltage requirements.

It is important to understand the differences between types of XHHW wire and their applications. Copper wiring is generally considerably heavier than its counterpart, aluminum wire. However, Copper conducts electricity much better, making it a more effective and expensive solution. Aluminum, on the other hand, is much lighter than Copper. However, with XHHW wire, this comes at a cost, as aluminum is less conductive than copper. While both forms of wiring offer considerable flexibility, it is critical to ensure that the wiring selected is the one most suitable to your installation requirements. Furthermore, in some localities, aluminum wiring may not be approved whereas copper wiring may be. Therefore, it is crucial when selecting the correct cabling to make certain to verify that the wiring selected meets any applicable standards or codes stipulated for your application.
