Burndy GAR3903 Copper Alloy Mechanical Grounding Connector

Burndy GAR3903 Copper Alloy Mechanical Grounding Connector for Water Pipe

The Burndy GAR3903 is a mechanical grounding connector engineered to bond copper conductors directly to metallic water pipe, creating a dependable grounding electrode connection for electrical systems. Machined from copper alloy for long-term conductivity and corrosion resistance, this connector accepts conductors from 4 AWG up to 4/0 AWG, fits 1-1/4" to 2" pipe, and uses a 3/8" stud to deliver a secure mechanical clamp. It gives electricians a straightforward, single-conductor way to establish a code-compliant bond between grounding conductors and water piping systems in both new installations and service upgrades.

Key Features

• Wide Conductor Range: Accommodates 4 AWG to 4/0 AWG copper conductors, covering both solid and stranded wire for flexible grounding applications.
• Pipe Compatibility: Sized to fit 1-1/4" to 2" water pipe, allowing a direct connection to common metallic plumbing used as a grounding electrode.
• Durable Copper Alloy Construction: The copper alloy body resists corrosion and maintains reliable electrical conductivity over the life of the installation.
• 3/8" Clamping Stud: A 3/8" stud provides a solid mechanical clamp that keeps the conductor firmly seated against the pipe surface.
• Single-Conductor Design: Purpose-built as a cable-to-ground-rod, pipe, or tube connector for bonding one grounding conductor at a time.
• Mechanical Set-Type Connection: Installs with common hand tools, without the need for exothermic welding equipment, for fast field terminations.
