3/0 AWG XHHW/XHHW-2 Copper Building Wire– Main Feeder for Large Commercial and Industrial Power Systems

This 3/0 AWG XHHW/XHHW-2 copper building wire delivers the capacity required for main feeders in large-scale electrical systems. Engineered with a high-purity copper conductor (solid or stranded option) and XLPE cross-linked polyethylene insulation, it meets UL 44 standards. Offered in 600V, 1000V, and 2000V voltage classes. XHHW-2 insulation supports 90°C operation in dry and wet environments, providing long-term resistance to moisture, elevated temperatures, and chemical exposure commonly encountered in power distribution infrastructure.

Large cross-section effectively supports substantial continuous loads with minimal voltage drop. Stranded construction provides flexibility during conduit pulling and tray routing. The 3/0 AWG rating offers capacity for multiple downstream circuits. XLPE insulation ensures long service life and reduces maintenance concerns. Multiple color options available for phase identification in complex installations.

XHHW wire is UL certified, with certification number UL-US-2561137-0. The cable fully meets the stringent requirements of the North American market for building wires in terms of material selection, structural design, electrical performance, and safety standards, providing a solid guarantee for project compliance.

XHHW wire is primarily used for service entrance, feeder, and branch circuit wiring in building electrical systems, and is widely used in commercial buildings, industrial facilities, and large residential projects.
