The newest generation of XHHW wire is Cross-Linked Polyethylene High Heat-resistant Water-Resistant (XHHW-2). It is used in raceways, feeder, and circuit wiring, while its main designation is for use in residential, commercial, and industrial buildings
Manufactured with copper or aluminum conductors, this wire is either solid or stranded cable. A larger size wire is stranded to maintain flexibility.
XHHW-2 is approved for use up to 600 volts and rated by UL for 90 degrees Celsius in dry and wet locations. The previous generation of XHHW had a lower temperature rate. It was only approved up to 75 degrees Celsius in wet environments, making the new XHHW-2 generation a more desirable product
