Value Collection B20 Bare Copper Bus Bar Wire 20 Awg

Product Description

The VALUE COLLECTION B20 is a bare copper bus bar wire supplied in a 79-foot length at 20 AWG, with a diameter of 0.032 inches. Manufactured to ASTM B3 standards, it is made from pure copper, delivering reliable electrical conductivity for grounding, bonding, and bus bar fabrication work. Electricians, panel builders, and electrical contractors use this wire in applications requiring a soft, uncoated copper conductor. The bare finish allows for direct termination without stripping insulation, making it well suited for shop fabrication, custom bus bar assemblies, and low-voltage wiring projects.

This wire is used in residential and commercial electrical work where bare copper conductors are required. Common applications include grounding electrode conductors, neutral bus connections, panelboard fabrication, and transformer secondary connections. At 20 AWG, it is appropriate for low-current circuits, instrumentation wiring, and bonding jumpers in control panels. The 79-foot spool length suits both bench fabrication and field work without excessive waste.

Key Features

• Pure copper construction conforming to ASTM B3 for consistent conductivity and ductility
• Bare finish allows direct termination without insulation removal
• 20 AWG gauge with 0.032-inch diameter for low-current and instrumentation applications
• 79-foot length provides sufficient stock for panel fabrication or multiple small runs
• Soft-drawn copper wire bends and forms easily for bus bar shaping and routing

Compatibility

Designed as a general-purpose bare copper conductor suitable for use in bus bar assemblies, grounding systems, and control panel wiring where ASTM B3 soft-drawn copper wire at 20 AWG is specified.

Installation Notes

Installation of bare copper bus bar wire should be performed by a licensed electrician in accordance with the National Electrical Code (NEC). De-energize and lock out all circuits before making connections. Use appropriate terminal hardware rated for the conductor size and application. Avoid kinking or sharp bends that could reduce the cross-section and compromise conductivity.
