Bare Copper bare250mcmstr19sdmr 250 Mcm Copper Wire

Product Description

The BARE COPPER bare250mcmstr19sdmr is a 250 MCM (250 kcmil) bare soft drawn copper conductor with 19-strand construction, supplied in cut-to-length format. Soft drawn copper offers greater flexibility than hard drawn wire, making it well suited for grounding electrode systems, bonding applications, and bare overhead or underground distribution work. The 19-strand configuration improves flexibility and handling compared to solid conductors of the same gauge. With an outer diameter of 0.542 inches and a linear weight of 772 pounds per thousand feet, this conductor is sized for high-current grounding, bonding, and utility distribution use cases.

This bare copper conductor is used in commercial and residential electrical installations where an uninsulated copper conductor is required. Typical applications include grounding electrode conductors, ground rings, equipment bonding jumpers, and neutral conductors in certain overhead distribution configurations. It is available cut to length, which is practical for contractors pulling specific runs without waste from a standard reel. Electricians and utility linemen are the primary installers of this product.

Key Features

• 250 MCM (250 kcmil) conductor size for high-current grounding and bonding circuits
• 19-strand soft drawn copper construction for improved flexibility and easier pulling
• Bare uninsulated finish suitable for direct burial, grounding, and bonding applications
• 0.542-inch outer diameter for conduit fill and lug sizing reference
• Cut-to-length availability reduces scrap on fixed-run installations
• Linear weight of 772 pounds per thousand feet for load and sag calculations

Compatibility

Designed as a standard bare copper grounding and bonding conductor compatible with compression lugs, mechanical connectors, and grounding clamps rated for 250 MCM copper conductors. Verify connector and lug ratings before installation.

Installation Notes

Installation of grounding electrode conductors and bonding jumpers must comply with applicable NEC article requirements for sizing, routing, and protection. De-energize all circuits and verify absence of voltage before making connections to any grounding or bonding system. Use only compression or mechanical connectors listed and rated for bare copper conductors at 250 MCM. Licensed electricians or qualified utility personnel should perform all installations in accordance with local adopted codes.
