Bare Copper bare500mcmstr37sdmr 500 Kcmil Bare Copper Wire

Product Description

The BARE COPPER bare500mcmstr37sdmr is a 500 kcmil, 37-strand soft drawn bare copper conductor sold cut to length. Soft drawn stranding produces a highly flexible cable that pulls easily through conduit and bends around obstacles without kinking. At 0.766 inches outer diameter and a weight of 1,544 pounds per thousand feet, this conductor is sized for high-ampacity feeder and grounding applications. Electricians and electrical contractors specify bare copper in this size range for equipment grounding conductors, grounding electrode conductors, and exposed bus work in switchgear, substations, and industrial facilities.

This conductor is suited for commercial and industrial electrical installations where a large-gauge bare copper ground or feeder is required. Typical applications include main service entrance grounding, lightning protection bonding, substation grounding grids, and direct-burial grounding runs where the installation code permits bare copper. The cut-to-length format eliminates waste on job sites where a standard 1,000-foot reel is not required.

Key Features

• 500 kcmil conductor size for high-ampacity grounding and feeder applications
• 37-strand configuration provides increased flexibility compared to solid or low-strand-count conductors
• Soft drawn copper construction allows easier bending and routing in tight spaces
• Bare copper finish with no insulation or jacket — suitable for grounding and bonding runs
• 0.766 inch outer diameter for conduit fill calculations
• Cut-to-length availability reduces material waste on custom-length runs

Compatibility

Designed as a general-purpose bare copper conductor for use in grounding, bonding, and exposed bus applications in commercial and industrial electrical systems where 500 kcmil bare copper is specified.

Installation Notes

Installation of 500 kcmil bare copper conductors should be performed by a licensed electrician in accordance with applicable NEC requirements for grounding electrode conductors and equipment grounding conductors. Verify conduit fill compliance using the 0.766 inch outer diameter before pulling. De-energize and lock out all circuits before making terminations. Use appropriately rated compression lugs or irreversible crimp connectors rated for 500 kcmil bare copper — do not use mechanical set-screw connectors unless they are specifically listed for bare copper at this size.
