Copper xhhw-250-blk-37str-cu-1000r Xhhw Cable 250 Kcmil

Product Description

The COPPER xhhw-250-blk-37str-cu-1000r is a 250 KCMIL stranded copper XHHW building wire supplied on a 1000-foot reel. It carries a 600-volt rating and a 90 degrees C temperature rating, making it appropriate for power distribution wiring in conduit and cable tray installations. The conductor is built from 37-strand copper, which provides flexibility during pull-in compared to solid or lower-strand-count alternatives. Licensed electricians install this wire as part of service entrance, feeder, and branch circuit work in commercial and industrial projects.

This wire is intended for use in conduit or cable tray systems supporting services, feeders, and branch circuits in commercial and industrial applications. The 250 KCMIL size is commonly specified for medium-to-large feeder runs where ampacity and voltage-drop requirements exceed what smaller conductors can meet. The black insulation color is standard for phase identification in multi-conductor feeder assemblies. The 1000-foot reel format suits larger projects where pulling long continuous runs is required.

Key Features

• 250 KCMIL stranded copper conductor for high-ampacity feeder and service applications
• 37-strand construction improves pull-in flexibility in conduit
• 600-volt rating suits standard commercial and industrial power distribution circuits
• 90 degrees C temperature rating supports use in higher-ambient environments
• XHHW insulation rated for use in conduit and cable tray installations
• RoHS compliant

Compatibility

Suitable for use in conduit and cable tray systems for services, feeders, and branch circuits in commercial and industrial applications. Designed as a standard XHHW-2 style stranded copper building wire for use where 250 KCMIL conductors are specified.

Installation Notes

Installation must be performed by a licensed electrician in accordance with applicable NEC requirements for conductor sizing, conduit fill, and termination torque specifications per the equipment manufacturer. De-energize all circuits and verify absence of voltage before pulling or terminating conductors. Use appropriate wire-pulling lubricant when pulling 250 KCMIL conductors through conduit to avoid insulation damage. Terminate only in lugs or connectors rated for 250 KCMIL stranded copper conductors.
