Copper XHHW Wire
About Copper XHHW Wire
We stock XHHW electrical wire in our NH warehouse and throughout the USA due to our manufacturer’s stocking locations. We have the ability to drop ship our XHHW and THHN THWN wire when necessary. XHHW is a sunlight resistant electrical wire due to its cross-linked polyethylene insulation. It’s commonly used in conduit and raceway underground but can not be directly buried in the ground without conduit. Its temperature rating goes up as high as 90°C and the voltage rating is 600 volts on all sizes listed above.
