Burndy GAR3904BU Mechanical Ground Connector, Conductor to Water Pipe

Burndy GAR3904BU Mechanical Ground Connector, Conductor to Water Pipe

The Burndy GAR3904BU is a mechanical grounding connector engineered to join a conductor directly to a water pipe grounding electrode. Rated for 4-4/0 AWG conductors and sized to fit 2-1/2"-3-1/2" pipe, this connector uses a 3/8" stud along with silicon bronze hardware to form a secure, corrosion-resistant mechanical connection. It is built for grounding and bonding applications where a dependable conductor-to-pipe connection is required in commercial and industrial electrical systems, service entrance grounding, and water pipe grounding electrode installations.

Key Features

• Conductor Range: Accommodates 4 AWG through 4/0 AWG copper conductors, covering solid and stranded conductor sizes for flexible grounding and bonding work.
• Pipe Size: Fits 2-1/2"-3-1/2" water pipe, matching the connector to standard water pipe grounding electrode diameters.
• Stud Size: A 3/8" stud provides a secure, code-recognized mounting point for the conductor termination.
• Durable Construction: Copper alloy body construction resists corrosion and supports long-term reliability in grounding and bonding environments.
• Silicon Bronze Hardware: Silicon bronze hardware delivers long-term mechanical integrity and corrosion resistance at the connection point.
• Mechanical Connection Type: Conductor-to-pipe mechanical design simplifies field installation without specialized crimping tools.
